Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list.

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair!

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.

3 Ways Diabetes Can Affect Your Vision and Eyes

Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.

But First, What Is Diabetes?

Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.

Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.

What’s the Link Between Vision and Diabetes?

Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.

If you start to notice blurry vision, make an appointment with Dr. Richard E. Hults as soon as possible.

The 3 Ways Diabetes Impacts Vision

Cataracts

While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.

Glaucoma

Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.

Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.

Diabetic Retinopathy

Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.

Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.

The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact Dr. Richard E. Hults & Assoc., Inc in Canton to set up your eye doctor’s appointment today.

Diabetes and Your Eyes

Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.

Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.

What is Diabetes?

Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.

How Does Diabetes Affect The Eyes?

Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.

In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.

The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.

Diabetic Retinopathy

As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.

The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.

Signs and Symptoms of Diabetic Retinopathy

The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:

  • Blurred or fluctuating vision or vision loss
  • Floaters (dark spots or strings that appear to float in your visual field)
  • Blind spots
  • Color vision loss

There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.

A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.

Retinal Detachment

Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.

Diabetic Macular Edema (DME)

Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.

Treatment for Diabetic Retinopathy and Diabetic Macular Edema

While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.

Prevent Vision Loss from Diabetes

The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

 

Women and Diabetes – World Diabetes Day

November 14th is World Diabetes Day. This year, the theme of World Diabetes Day is women and diabetes – our right to a healthy future. The goal of this campaign is to promote awareness of the importance of equal and affordable access for all women, whether they are at risk or already living with diabetes, to the treatments, medications, technology, education and information they need to prevent diabetes and to obtain the best possible outcome of the disease.

Here are some facts about women and diabetes around the World:

  • 199 million – the number of women living with diabetes to date.
  • 313 million – the projected statistic for the year 2040.
  • 2.1 million – the number of female deaths due to diabetes per year.
  • 9 – diabetes is the ninth leading cause of death in women on a global scale.
  • 60 million – which is 2 out of 5 diabetic women, are of reproductive age, which increases the risk of early miscarriage, vision loss and having malformed babies.
  • 10 – women with type 2 diabetes are ten times more likely to develop coronary heart disease.

Much of these incidences of diabetes occur in women lacking access to proper medical care, education, physical activity and information they need to prevent and manage the disease. If more efforts and monies were put toward improving this situation, these numbers could drop significantly.

Pregnant women with hyperglycemia and gestational diabetes are also a major cause of concern. Limited access to screening tests, pre-pregnancy planning services, education and medical care could also improve the outcome of both the mother and the baby in these cases. The majority of instances of gestational diabetes occur in women from low and middle-income countries or households with limited access to maternal care.

Here are some additional facts about diabetes and pregnancy:

  • 1 out of 7 – the number of births worldwide affected by gestational diabetes.
  • 1 out of 2 – the number of women with gestational diabetes that develop type 2 diabetes within 5-10 years after giving birth.
  • 1 out of 2 – the number of cases of gestational diabetes that are found in women under 30 years of age.

Diabetes and Your Eyes

Diabetes damages many systems in your body including your eyes and vision. Most individuals with diabetes will eventually develop some extent of retinopathy or eye disease due to the consistently high levels of glucose in the blood which damage the blood vessels in the eye. Diabetic retinopathy can be a devastating disease that can leave you with permanent vision loss or blindness. It is a leading cause of blindness worldwide. Diabetes also speeds up the formation of cataracts and other ocular diseases which can lead to further vision loss and complications.

Women who have been diagnosed with diabetes prior to becoming pregnant have to be especially careful during pregnancy. It is much more difficult to regulate blood sugars during pregnancy, and more rapid progression of diabetic retinopathy can occur if one is not careful. Keeping track of diet and exercise, and taking medications as directed, can prevent or delay the impact of diabetes on the eyes.

In addition to poorly managed blood sugar levels, additional factors that contribute to developing diabetic retinopathy are high blood pressure, high cholesterol, Hispanic or Native American descent, smoking, pregnancy, and the length of time you have the disease. The condition can be managed with regular eye exams in combination with steps to control blood sugar levels.

It’s important to note that diabetes sometimes causes symptoms of vision fluctuation (good days and bad days with vision or focusing) but many times the damage is asymptomatic in its early stages. This is why it is essential to have regular checkups even when you have no pain or vision symptoms.

If you or someone you know has diabetes, regular eye exams are essential to monitor and prevent vision loss. Stay informed and spread awareness about this challenging condition. You can help be part of the change to improve the lives of women and people all over the world that suffer from diabetes and the serious complications that come with it.

November is Diabetes Awareness Month

father 20waving 20with 20child

Diabetes is a growing health crisis in North America as an estimated 29 million Americans and 3.4 million Canadians are currently living with the disease. Chances are it affects you or someone you know. November has been dedicated as a time to spread awareness about the disease, its risk factors and the effects it has on your body, your daily life and the lives of your loved ones.

Diabetes and Your Eyes

Diabetes is a systemic disease that causes fluctuations in glucose (blood sugar) levels which can affect blood vessels throughout the body including those in your eyes and visual system. People with diabetes are at higher risk for blindness than the general population, however with regular eye exams and proper care, most of the complications are minor and treatable.

Minor changes in glucose levels could result in complications such as blurred or double vision, floaters or even visual field loss. These conditions are usually quite treatable. Diabetics are also at greater risk for developing eye diseases such as glaucoma (40% increase risk) and cataracts (60% increased risk). With early detection, both of these conditions can be treated and the majority of vision restored.

Diabetic eye disease often has NO noticeable symptoms or pain, so comprehensive eye exams that include dilating the pupils are essential to detect signs of diabetes. Online vision assessments will not detect diabetic eye disease.

The condition that is the most concerning risk of diabetes is called diabetic retinopathy which can lead to blindness if not diagnosed and treated.

What You Need to Know About Diabetic Retinopathy

Diabetic retinopathy occurs when the tiny blood vessels or capillaries in the back of the eye develop weakened vessel walls. If not treated, the vessels leak fluid and become blocked. This can progress to hemorrhages in the retina, and over time the eye does not receive enough oxygen and nutrients. As a result, new fine blood vessels start to grow. These proliferating vessels leak and can cause further bleeding, scarring and potentially lead to blindness. A special zone in the central retina called the macula is especially susceptible to diabetes. Diabetic macular edema (when fluid seeps into the macula) can cause permanent vision loss if not promptly detected.

There are treatments for stopping the progression of the disease such as laser therapy or intraocular injections, although once damage to vision has occurred, it is often permanent. This is why the condition must be diagnosed and treated early on.

All diabetics should have a regular comprehensive eye exam to catch any early signs of diabetic retinopathy or other vision threatening conditions. Because risk factors vary, speak to your eye doctor about how often you should have an exam. Risk factors for diabetic retinopathy include:

  • Length of time living with diabetes
  • Uncontrolled blood sugar levels
  • High blood pressure
  • Smoking
  • Alcohol consumption
  • Pregnancy
  • Genetics

Although blindness from diabetes is preventable it is still a leading cause of blindness among working-age adults. If you or someone you know has the disease, make sure that proper eye care is a priority.

Do You Know the Facts About Diabetic Eye Disease?

woman in thought

If you or a loved one suffers from diabetes, awareness of the threat of vision loss due to diabetic eye disease should be a top priority. Don’t wait until it is too late to learn about the risks.

Here are eight true and false questions about diabetic eye disease to test your knowledge. If you have any questions, contact your eye care professional to find out more.

1) Diabetic Retinopathy is the only eye and vision risk associated with diabetes.

FALSE: People with diabetes have a higher risk of not only losing sight through diabetic retinopathy, but also a greater chance of developing other eye diseases such as cataracts and glaucoma. People with diabetes are 40% more likely to develop glaucoma and this number increases with age and the amount of time the individual has diabetes. Diabetics are also 60% more likely to develop cataracts and at an earlier age than those without diabetes. Additionally, during the advanced stages of diabetes, people can also lose corneal sensitivity and develop double vision from eye muscle palsies.

2) Diabetic retinopathy can cause blindness.

True: In fact, diabetes is the leading cause of blindness in adults age 20 to 74.

3) With proper treatment, diabetic eye disease is reversible.

FALSE: Although early detection and timely treatment can greatly reduce the chances of vision loss from diabetic eye disease, without prompt and preventative treatment measures, diabetic eye disease can result in permanent vision loss and even blindness. Currently, there is no cure that reverses lost eyesight from diabetic retinopathy; however, there are a variety of low vision aids that can improve quality of life for those with vision loss.

4) People who have good control of their diabetes and their blood glucose levels are not at high risk for diabetic eye disease.

FALSE: While studies do show that proper management of blood sugar levels in diabetics can slow the onset and progression of diabetic retinopathy, there is a still a higher risk of developing diabetic eye disease. Age and length of the disease can be factors for eye diseases such as glaucoma and cataracts. The risk of diabetic retinopathy can be influenced by factors such as blood sugar control, blood pressure levels, how long the person has had diabetes and genetics.

5) You can always prevent diabetic eye disease by paying attention to the early warning signs

FALSE: Oftentimes there aren’t any early warning signs of diabetic eye disease and vision loss only starts to become apparent when the disease is already at an advanced and irreversible stage.

6) A yearly, dilated eye exam can help prevent vision loss through diabetic eye disease.

TRUE: Diabetics should get a dilated eye exam at least once a year. Since diabetic eye disease often has no symptoms, routine eye exams are critical for early detection and treatment. Everyone with diabetes should get an eye examination through dilated pupils every year, because it can reduce the risk of blindness from diabetic eye disease by up to 95%.

7) Both type 1 and type 2 diabetes are at risk of developing diabetic eye disease.

TRUE: Everyone with diabetes – even gestational diabetes – is at risk and should have a yearly eye exam. In fact, 40% to 45% of those diagnosed with diabetes have some stage of diabetic retinopathy.

8) Smoking increases the risk of diabetic eye disease.

TRUE: In addition to getting regular eye exams, stop smoking, partake in daily physical activity, maintain a healthy weight and control blood sugar, blood pressure and cholesterol: they all help reduce the risks of eye disease.

Whatever your score on the quiz above, the most important take-away is that if you have diabetes, even if you aren’t having any symptoms of vision loss: make an appointment for a comprehensive, dilated eye exam every year. It could save your sight.

What You Should Know about Diabetes and Your Vision

couple 20walking 20away

Diabetes affects people of all ages, races and genders. An estimated 25.8 million Americans or 8.3 percent of the population suffer from the disease, according to data published by the Centers for Disease Control and Prevention in 2011. In fact, diabetic eye disease is the leading cause of new cases of blindness among adults in the North America.

If you or someone you care for has diabetes, here are 6 things you need to know about how it impacts eyes and vision.

  1. What is diabetic eye disease?
    Diabetic eye disease is most commonly associated with diabetic retinopathy, which is characterized by damage to the blood vessels of the retina and can lead to blindness. According to the National Eye Institute, it can also cause premature cataracts and glaucoma.
  2. How does it impact vision?
    In diabetic retinopathy, the small blood vessels that nourish the retina at the back of the eye become weak as a result of fluctuating sugar levels in the bloodstream. This causes bleeding at the back of the eye, reduced circulation and less oxygen and nutrients reaching the retina. As a result, new fragile blood vessels are produced to compensate. However, the abnormal blood vessels can start leaking fluid and small amounts of blood into the retina, causing vision loss. In the worst cases, the retina can scar or detach, causing permanent vision loss.
  3. What are the symptoms?
    At first, someone with diabetic retinopathy may not experience any noticeable symptoms. That is why early detection is crucial and diabetics should have a dilated eye exam at least once a year to screen for diabetic retinopathy. In most cases, by the time you realize something is wrong, the disease is so far advanced that lost vision can’t be restored.In its advanced stage symptoms may include:

    • Fluctuating vision
    • Eye floaters and spots
    • The development of a shadow in your field of view
    • Blurry vision, or double vision
  4. Who is at risk?
    Anyone who has diabetes type 1 or type 2 has a greater chance of developing vision loss. Even gestational diabetes and pre-diabetes increase the risk of diabetic eye disease. An estimated 40 to 45 percent of Americans diagnosed with diabetes have some degree of diabetic retinopathy, according to the NEI. That is why anyone with diabetes should have a comprehensive dilated eye exam at least once a year. The longer you have diabetes, the more likely it is to have an effect on your vision.Race and family history can also put you at risk for the disease. If you are of Hispanic, African, Asian, Pacific Island, or Native American descent, you are more likely to develop diabetes. Lifestyle – including your weight, diet and how active you are – also plays a role in the development and management of diabetes, as well as its effect on the eyes.
  5. How is diabetic eye disease treated?
    There are effective medical treatments, including injections into the eye to prevent leaking blood vessels and laser treatment to prevent and reduce vision loss as a result of diabetes, but early detection and treatment are vital!
  6. What steps can I take to reduce diabetes related vision loss?
    Make sure to keep your blood sugar levels under control and monitor your blood pressure and cholesterol. Speak to your doctor about what your target goals should be to prevent further deterioration. Often, when diabetes causes damage to the eyes, it is also an indication of the damage occurring in the kidneys and other areas in the body with small nerves and blood vessels, too. Exercise, maintain a healthy diet and keep your cholesterol levels low. Schedule eye exams yearly or as often as your eye doctor and medical doctor advise.

Knowing the risks and symptoms of diabetic retinopathy is not enough. If you or a loved one has diabetes, don’t take chances. The only real way to safeguard your vision is by making your eye health a priority.

Take a diabetes risk test.

A Closer Look at Diabetic Eye Disease

Are you aware that having diabetes increases your chances of contracting several eye-related diseases? These conditions include diabetic retinopathy, cataracts and glaucoma, and also a number of other conditions that, even though they may be seemingly unrelated to your sight, can effect your vision.

Diabetic retinopathy, which occurs when high blood glucose levels cause harm to the network of blood vessels in the retina. It can also lead to blindness in adults.

A pretty familiar result of old age, cataracts, which lead to a clouding of the eye’s lens, and the subsequent worsening of vision, usually develop sooner in diabetes sufferers.

Your odds of developing glaucoma, another condition that can lead to vision impairment, double when you suffer from diabetes. This condition forms due to escalating pressure in the eye, resulting in damage of nerves in the eye and loss of vision.

All diabetes sufferers, type 1 or 2, are at increased risk of diabetic eye disease. The risk is even higher if the diabetes isn’t adequately controlled. Other risks include:

  • High blood pressure
  • High cholesterol
  • Smoking
  • Obesity
  • Duration of the disease
  • Age
  • Bad diet and exercise habits
  • Race í research suggests that African-Americans and Hispanics may be at higher risk of developing diabetic retinopathy and vision loss.

Symptoms of diabetic eye diseases usually change with blood sugar levels. These often include:

  • Double vision
  • Eye pain
  • Blurred vision and blind spots
  • Seeing floaters, or shadow in the field of view
  • Trouble with near vision
  • Corneal abrasions

Unfortunately, these symptoms are more than warning signs. The onset of diabetic eye disease can actually occur before its symptoms do.

Detecting the condition before these symptoms surface can make all the difference when it comes to avoiding irreversible vision loss. Because of this, people with diabetes are strongly encouraged to go get a yearly eye exam to keep tabs on the health of their eyes. If you have diabetes, make sure you are educated about the risks and prevention of diabetic eye disease. Annual eye exams, coupled with good lifestyle choices, can make the difference between losing vision and seeing well for years to come.

Know the Risks of Diabetic Eye Disease

While many people have heard of diabetes, they may not be informed about the impact that it can have on your eyes. Diabetes is a disease that affects the metabolic process that results in elevated levels of glucose in the blood either due to insufficient production of insulin or because the body’s mechanism to utilize insulin is disrupted.

The threat of vision loss is increased when diabetes is not controlled. Diabetic eye disease can come in a number of forms.

The most serious diabetic eye disease is one that can lead to damage to the blood vessels that lead to the retina. This condition is a primary cause of blindness in adults and is called diabetic retinopathy.

Located at the back of the eye, the retina is a necessary component for proper vision. Damage to the retina can result in irreversible vision loss. While controlling diabetes can reduce the chances of developing diabetic retinopathy, it does not entirely eliminate the risk and consequently it is essential to have your eyes checked each year if you have diabetes.

Glucose levels that change regularly can also affect vision. Since glucose levels have an impact on your lens’s ability to maintain sharp focus, this can result in blurred vision that varies with blood sugar levels.

Diabetics are at greater risk to develop cataracts, a condition in which the lens of the eye becomes clouded, which impacts vision. Cataracts are a common condition that comes with aging, but happens at an earlier age in diabetics.

Glaucoma, which is caused by increased pressure in the optic nerve, can cause vision loss. Diabetics are two times more likely to develop glaucoma.

Having control of your diabetes is the best form of prevention for any of the eye and vision problems associated with the disease. As well as controlling levels of glucose through diet and/or insulin, it’s important to exercise and refrain from smoking. Additionally, it is imperative to schedule regular yearly retinal exams with an eye doctor to detect any possible problems at the earliest stages. Even though often vision loss that results from any of these conditions cannot be reversed, early diagnosis and treatment can often stop continuing damage and disease progression.

Diabetes: A Leading Cause of Vision Loss

Did you know that diabetes is the number one causal factor of impaired sight among men and women between age twenty and seventy-four? In the past four years alone, over four million people in North America living with diabetes were diagnosed with diabetic retinopathy. Of this group, 70,000 had severe diabetic retinopathy, which may result in a complete vision loss.

While not every individual is at risk of diabetes related vision loss, it is essential to understand the connection between the disease and blindness.

Having a diagnosis of diabetes is the first risk factor. One way to find out if you have diabetic retinopathy is to have your optometrist test your vision yearly. The longer the disease remains undiagnosed, the greater the risk of diabetes related vision loss. Quick treatment is necessary to halting further deterioration.

Women who are expecting that are afflicted with gestational diabetes have a better likelihood of developing diabetic retinopathy. It is advisable to schedule a complete dilated eye examination after diagnosis as well.

You may ask yourself why all the panic? Wouldn’t there be tell tale symptoms if you were going blind?

The answer surprisingly is, not necessarily. There are different forms of diabetic retinopathy, and only those which are in the acute stages are obvious. Advanced diabetes might have no signs. Macular edema is another diabetes caused disease which results in severe vision loss, which may appear without obvious signs. This is why early discovery is the key to preventing lasting loss.

An extensive analysis will detect evidence of diabetic retinopathy. There are individual parts to this exam which will show the standard signs, such as damaged nerve tissue, swelling of the retina, and leaky blood vessels. Want to know what are the steps in a comprehensive vision exam?

The eye doctor will perform an examination of visual acuity by means of an eye chart that is used to assess how well you can see at varying distances. This is similar to the visual acuity tests given by optometrists, if you require corrective lenses.

To give a dilated eye exam, the optometrist puts drops in your eyes to amplify the size of your pupils. Though not a favorite of most people, it can save you a loss of autonomy later on. This measure makes it possible to monitor a larger section of the inside of your eyes to look for specific signs that indicate the presence of diabetic retinopathy. The fleeting discomfort will probably save your eye sight.

It is important to value your sight. Even a little hesitation can cause severe damage. If you have been diagnosed with diabetes, it is imperative to schedule a vision exam with your eye doctor once a year without fail.
