Diabetes and Eye Problems

How diabetes affects your eyes

High blood sugar (glucose) is the main problem. Diabetes is when your body doesn’t properly make or use insulin. This raises blood sugar. This can cause fluid loss in your eye areas that aid you in focusing. Sometimes you may not notice any symptoms or blurry vision for several days or weeks. It will usually return to normal after your glucose levels are lower.

Long-term effects of high glucose

High blood sugar levels can cause damage to the blood vessels behind your eyes. These vessels can leak fluid, causing swelling, pressure, and other problems. If you have high glucose levels, damage may begin before symptoms of diabetes appear elsewhere in your body. Four diabetes-related eye problems can result in macular edema (retinopathy), macular edema (glaucoma), and cataracts.

Diabetic Retinopathy in Early Diabetic Retinopathy

Early nonproliferative diabetic nephropathy (NPDR) is a condition in which blood vessels bulge out of the back of your eye and leak into the retina’s inner lining. Your nerve endings might swell, too. At first, symptoms may not be apparent. If you are concerned about your eye health, consult your doctor. It is important to manage it early.

Advanced Diabetic Retinopathy

The blood vessels in the back of your eyes begin to close. They’re not damaged, but new ones can grow in your retina. They can get into your vitreous, the jelly-like substance that lies in the middle and back of your eye. It is possible to see streaks or dark spots that appear to be floating in your field of vision. Scar tissue can form if you don’t seek treatment immediately. This can lead to severe complications, including the possibility of separating the retina from your back eye.

Diabetic Macular Emma

Sometimes, fluid can build up in the macula of the retina. It is essential to drive, read, recognize faces and drive cars. If your macula becomes larger, your vision may be blurred or lose all or part of its clarity. DME is available to approximately half of those who develop diabetic retinopathy.


There are many types of pressure, but all pressure is your optic nerve that connects to the brain. Sometimes you may not notice any symptoms or lose your side vision. Because it occurs slowly, you may not notice. It can cause permanent vision loss if you don’t address it.


A cataract is a cloudy lens that makes your eyes look blurry. This blocks light and makes everything look hazy. This can be accelerated by poor blood sugar control. Diabetes is more likely to cause cataracts, and they will usually develop earlier. Although surgery can remove the cloudy lens and replace it with an artificial one, diabetic retinopathy can sometimes worsen if you don’t have good blood sugar control.

Diagnosis for Diabetic Eye Disease

If you think you may have diabetes, your doctor will test your eyes and measure your eye pressure. The doctor will use medicated eye drops to widen the pupils (the part of your eyes that allows light in) so that they can see the back of the eye. A dye might be injected into your arm by the doctor. This dye may show signs of leakage in your small blood vessels. After the exam, your vision may be blurred for a few hours.

Early Treatment

Your doctor may recommend more frequent eye exams to ensure your eyes are healthy. Diabetes management may be the only option. You’ll usually keep track of your blood sugar, cholesterol and blood pressure and attempt to control them. You can get help with prescription medication, exercise, better-eating habits, and quitting smoking.

Laser Treatment

Panretinal Photocoagulation uses a laser for areas of the retina where blood vessels are abnormal. Focal treatment is a less common procedure that uses a laser to close blood vessels and prevent them from growing. These surgeries can prevent vision loss from becoming worse.
