Diabetes and Eyesight

Diabetes is a disease that affects the way we process food for energy and growth. With all forms of diabetes—type 1, type 2 and gestational diabetes—the body has trouble converting sugar in the blood into energy, resulting in a host of potential health problems.

What exactly causes diabetic retinopathy?

Diabetic retinopathy is caused by poorly controlled blood sugars or occasionally, having diabetes for many years.

What is the first sign of diabetic retinopathy?

Often there are NO symptoms. Diabetes related vision changes can occur so gradually until the damage is so progressed that vision cant’ be restored.

Is diabetic retinopathy preventable or reversible?

Diabetic retinopathy is certainly preventable with proper blood sugar control, but once the retinal damage occurs, it can be treated but not reversed.

How often should diabetics get eye exams?

Diabetics need to get their eyes examined every year.

What are the four stages of diabetic retinopathy?

There are various stages of the retinal damage: mild, moderate, severe, and proliferative retinopathy. Each is defined by the amount of blood and protein leaking into the retina and the extent of the retina affected.

 

Can eye damage caused by diabetes be reversed?

The eye damage cannot be reversed. The leaky vessels can be treated, but the damage is permanent. Also, diabetics are twice as likely to develop both cataracts and glaucoma

Diabetes increases the likelihood that common diabetes-related vision problems or diseases might occur:

  • Diabetics are prone to developing cataracts (a clouding of the eye’s lens) at an earlier age.
  • People with diabetes are almost 50% more likely to develop glaucoma, an eye disorder that damages the optic nerve often marked by an increase of internal eye pressure.
  • Macular edema (and macular degeneration) are more common in diabetics due to malfunctioning blood vessels in the middle region of the retina responsible for central, sharp vision.
  • Most notably, diabetes can result in diabetic retinopathy; an eye disease that affects the blood vessels in the all-important retina. Nearly 45 percent of Americans diagnosed with diabetes have some stage of diabetic retinopathy.

That’s why there’s no separating diabetes and vision. If you have diabetes, then you should understand vision problems that increase in likelihood as a result of the disease.

Diabetes Statistics

Over 21 million people in the United States have diabetes, with an estimated additional 6 million people unaware they have a form of the disease. What’s more, an estimated 54 million Americans ages 40 to 74 have prediabetes, a condition that puts them at risk for developing type 2 diabetes. According to a recent American Optometric Association survey, diabetes is the leading cause of new cases of blindness among adults ages 20 to 74.
