Diabetic eye disease is a diabetes complication that affects eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina).

The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.

What causes diabetic eye disease?

Chronically high blood sugar from diabetes is associated with damage to the tiny blood vessels in the retina, leading to diabetic eye disease. The retina detects light and converts it to signals sent through the optic nerve to the brain. Diabetic eye disease can cause blood vessels in the retina to leak fluid or hemorrhage (bleed), distorting vision. In its most advanced stage, new abnormal blood vessels proliferate (increase in number) on the surface of the retina, which can lead to scarring and cell loss in the retina.

Diabetic Eye Disease Treatment:

Diabetic eye disease Treatment is to prevent it. Strict control of your blood sugar will significantly reduce the long-term risk of vision loss. Treatment usually won’t cure diabetic eye disease nor does it usually restore normal vision, but it may slow the progression of vision loss. Without treatment, diabetic eye disease progresses steadily from minimal to severe stages.

The laser is a very bright, finely focused light. It passes through the clear cornea, lens and vitreous without affecting them in any way. Laser surgery shrinks abnormal new vessels and reduces macular swelling. Treatment is often recommended for people with macular edema, proliferative diabetic eye disease (PDR) and neovascular glaucoma.

With laser surgery for macular edema, tiny laser burns are applied near the macula to reduce fluid leakage. The main goal of treatment is to prevent further loss of vision by reducing the swelling of the macula. It is uncommon for people who have blurred vision from macular edema to recover normal vision, although some may experience partial improvement.

Diabetic Eye Disease Surgery:

Diabetic eye disease surgery is removal of the vitreous gel (vitrectomy). Vitrectomy does not cure the disease. But it may improve vision in people who have developed bleeding into the vitreous gel (vitreous hemorrhage), retinal detachment, or severe scar tissue formation.
