Facts About Diabetic Retinopathy

Diabetes is the major cause of blindness in adults ages 20-74.

Diabetic Retinopathy is the largest example of diabetic eye disease.

Up to 24,000 Americans lose their sight yearly due to diabetic retinopathy.

(Chous, 2006)

Risks

Anyone with diabetes is at risk of diabetic retinopathy.

Approximately 45% of diabetic Americans have diabetic retinopathy.

Four Stages of Diabetic Retinopathy

1. Mild Nonproliferative Retinopathy

2. Moderate Nonproliferative Retinopathy

3. Severe Nonproliferative Retinopathy

4. Proliferative Retinopathy(National Eye Institute, 2006)

Mild Nonproliferative Retinopathy

Microaneurysms are the first occurrences of diabetic retinopathy. This happens when the tiny blood vessels of the retina begin to swell.

Moderate Nonproliferative Retinopathy

Moderate---This is a progressive eye disease and damage to the blood vessels grows. The blood vessels become blocked.

Severe Nonproliferative Retinopathy

Severe---Blood supply is blocked causing the eye to signal the need for new blood vessels. Parts of the retina are deprived of blood and nourishment.

Proliferative Retinopathy

Proliferative---The retina sends signals so new blood vessels are created. These blood vessels are abnormal and more likely to hemorrhage due to the thin walls of the vessel. The walls of these vessels are weak and soon begin to hemorrhage.

Diabetic Retinopathy is caused when chronic high blood sugar damages the small blood vessels nourishing the retina. This will eventually affect both eyes. (National Eye Institute 2003)

In the latest stage of diabetic retinopathy, vision loss is characterized by blurriness, spots, and sometimes blindness.

Functional Implications Difficulty with fine details Visual fluctuations Seeing rippled images Blurred, hazy or double vision Some loss of field vision Difficulty seeing at night or in low light Sensitivity to light or glare Trouble focusing images

Treatment Patient Education It is NOT inevitable. Diabetic Retinopathy has

few symptoms but can be treated if diagnosed early.

Controlling blood sugar Laser photocoagulation---laser beams seal vessels

and stop new blood vessel growth Vitrectomy---removes blood and scar tissue to

allow light refraction (Juvenile Diabetes Research Foundation International,

2007)

Research

The National Eye Institute is conducting research with hopeful drugs that may stop the retina from sending alarm signals to promote new vessel growth.
