Diabetic Eye Exams: Why They’re Important 

Eye exams are important for your eye health, especially if you have diabetes. Several diabetes-related eye diseases can significantly impact your eye health and vision. If you have diabetes, why are regular eye exams so important?

Continue reading to learn more about how diabetes can affect your eye health and why diabetic eye exams are important.

How Can Diabetes Affect Your Eye Health & Vision? 

Diabetes can have a significant impact on your eye health. Blood vessels in the retina support your eyes, but they are sensitive to damage caused by high blood sugar.

When your blood glucose levels are too high, your blood vessels can become damaged, leading to swelling and leaking fluid in the eye. Several diabetes-related eye diseases develop from issues with the blood vessels in your eyes.

Blurred vision is common when your blood sugar levels become temporarily elevated, but this effect usually resolves itself with time. Besides your glucose levels affecting your vision, diabetes increases your risk of several eye diseases, including diabetic retinopathy, diabetic macular edema, cataracts, and glaucoma.

Diabetic Retinopathy

You’re at risk of diabetic retinopathy if you have type 1 or type 2 diabetes. This conditions symptoms are difficult to notice because they may not appear until your vision is affected.

There are two stages of diabetic retinopathy, nonproliferative and proliferative diabetic retinopathy. Nonproliferative diabetic retinopathy occurs when tiny bulges protrude from blood vessel walls within your eye. These bulges may break and leak fluid and blood into the retina.

When blood vessels become blocked, the disease has entered an advanced stage. This stage is known as proliferative diabetic retinopathy. These blocked blood vessels stop oxygen flow to the retina, causing new, abnormal vessels to develop as a replacement.

Diabetic Macular Edema

Diabetic macular edema develops from diabetic retinopathy. This condition occurs when leaking fluid causes the center of the retina (the macula) to swell, causing eventual vision loss. It’s one of the most common causes of vision loss for those with diabetic retinopathy.

Cataracts

cataract is the clouding of your eye’s lens. This condition is usually age-related, but someone with diabetes has an increased risk of developing cataracts.

Having cataracts affects your ability to see clearly, with your vision feeling as if you’re looking through a foggy window. While the early stages of cataracts may not affect your vision, this condition progresses with time.

Many people receive cataract surgery when vision is significantly affected.

Glaucoma

Glaucoma is a group of eye conditions that cause damage to your optic nerve. Many forms of glaucoma raise the pressure inside your eye, damaging the optic nerve and leading to potential vision loss.

Your risk of developing glaucoma is 40% higher if you have diabetes. This disease has little to no symptoms until your vision is affected, so early diagnosis is key to protecting your vision.

Diabetes increases your risk of several eye conditions, many of which have limited warning signs. If you have diabetes, regular examinations are vital for your eye health.

The Importance of Diabetic Eye Exams 

While everyone needs eye exams, consistent examinations are crucial for someone with diabetes. Diabetes increases your risk of several eye diseases, and many of them may not show symptoms until vision loss occurs.

Because these symptoms are hard to identify alone, you need an annual eye examination to determine if any issues are present. Without an annual exam, you may put yourself at risk of vision loss and other complications.

The earlier your eye doctor finds a problem, the earlier they can begin to treat it. A diabetic eye exam slightly differs from a standard examination; there is a focus on your eye health.

If you have diabetes, what can you expect during a diabetic eye exam?

What to Expect During Your Exam

A diabetic eye exam begins similarly to a standard eye exam. You’ll go through several preliminary tests, such as chart readings, cover tests, and a slit lamp exam to check your overall eyesight.

After preliminary tests, your optometrist will complete a dilated eye examination. After dilating your eyes, your eye doctor will look at the structure of your eye, including the retina, optic nerve, and surrounding blood vessels.

These tests can help your optometrist determine if you’re at risk of any diabetes-related eye diseases. If you have any relevant symptoms, you’ll receive a customized treatment plan to effectively manage or prevent an eye condition from worsening.

Diabetes can seem tricky to manage, but your optometrist is here to help. An annual diabetic eye exam allows your eye doctor to diagnose any potential problems and offer recommendations to manage your diabetes effectively.

Visit Your Optometrist Annually 

Visiting your eye doctor every year may feel tedious, but it’s the best way to help protect your vision. Diabetic retinopathy, diabetic macular edema, cataracts, and glaucoma can all lead to vision loss, and you may not notice any symptoms.

With an annual diabetic eye exam, you can help protect your eye health and vision from potential complications. If you need an eye exam, contact your optometrist today.
