Diabetes and Eye Health: What Blood Sugar and Blood Pressure Do to Your Eyes

Diabetes and eye health are closely linked. High blood sugar and high blood pressure (hypertension) can damage the tiny blood vessels in your eyes.

Left untreated, that damage can cause lasting vision problems. This guide covers how it happens, what to watch for and how to protect your sight in The Villages.

Diabetes and Eye Health: How They Connect

High blood sugar can damage the small blood vessels in the retina. The retina is the light-sensing layer at the back of your eye.

This damage is called diabetic retinopathy. Early on, it often has no symptoms, but over time it can cause vision loss.

Diabetes can also lead to other eye problems:

• Cataracts: The lens of the eye clouds, so your vision blurs.
• Glaucoma: Pressure builds up in the eye, which harms the optic nerve.
• Diabetic macular edema: Fluid collects in the part of the retina that gives sharp vision.

Keeping your diabetes in check helps protect your eyesight.

Tip: A regular diabetic eye exam can find diabetic retinopathy early, even before you notice symptoms. Book your eye exam with us today.

Who Is at Risk?

If you have Type 1 or Type 2 diabetes, your risk of eye problems is higher. Some things also add to the risk, including having diabetes for many years, swings in blood sugar and high cholesterol. Our guide to diabetic eye disease has more detail.

How High Blood Pressure Affects Your Eyes

High blood pressure strains your heart and arteries, and it also affects the blood vessels in your eyes. Eye problems linked to hypertension include:

• Hypertensive retinopathy: Damage to the retina from long-term high blood pressure.
• Choroidopathy: Fluid buildup under the retina.
• Optic neuropathy: Nerve damage from poor blood flow.

Uncontrolled blood pressure can harm your eyes over time, even if you take good care of the rest of your health.

An active Villages lifestyle helps, but age still raises the chance of high blood pressure. Regular eye exams catch small problems before they grow.

Warning Signs That Need a Call

Diabetes and high blood pressure can both cause subtle changes in your eyes. Look out for:

• Blurry or changing vision

• Spots or floaters

• Loss of side vision

• Trouble focusing, especially in low light

If you notice any of these, call your eye doctor soon.

Why Routine Eye Checks Matter for Diabetes and Eye Health

A good eye check for people with diabetes includes:

• Retinal imaging: This looks for early signs of retinopathy.
• Pressure tests: These help rule out glaucoma.
• Macular checks: These look for fluid buildup.

Studies suggest that people who keep up with eye exams and manage their diabetes and blood pressure are better able to protect their vision. Our dilated eye exams give a clear view of the back of the eye.

Tips for Protecting Diabetes and Eye Health

These steps protect your vision while you manage diabetes or hypertension.

1. Manage your numbers. Check and control your blood sugar and blood pressure often, so you can spot changes early.

2. Build healthy habits. Eat a balanced diet, exercise and get enough sleep.

3. Wear the right eyewear. Keep your prescription eyeglasses up to date so you see well.

4. Care for dry eyes. Many people with diabetes have dry eyes, which cause irritation, grittiness and changing vision. A good first step is artificial tears, which are lubricating eye drops.

   See the National Eye Institute page on dry eye or our page on dry eye treatment.

5. Quit smoking. Smoking speeds up the damage from both diabetes and high blood pressure, so quitting protects your eyes.
