Diabetic retinopathy is a condition occurring in persons with diabetes which causes progressive damage to the retina, the light sensitive lining at the back of the eye. It is a serious sight-threatening complication of diabetes. Diabetic retinopathy is the result of damage to the tiny blood vessels that nourish the retina. They leak blood and other fluids that cause swelling of retinal tissue and clouding of vision. The condition usually affects both eyes. The longer a person has diabetes, the more likely they will develop diabetic retinopathy. If left untreated, diabetic retinopathy can cause blindness.
Symptoms of Diabetic Retinopathy
Seeing spots or floaters in your field of vision
Having a dark or empty spot in the center of your vision
Difficulty seeing well at night
Treatment of Diabetic Retinopathy
Laser treatment (photocoagulation) is usually very effective at preventing vision loss if it is done before the retina has been severely damaged.
Surgical removal of the vitreous gel (vitrectomy) may also help improve vision if the retina has not been severely damaged.
Sometimes injections of an anti-VEGF (vascular endothelial growth factor) medicine or an anti-inflammatory medicine help to shrink new blood vessels in proliferative diabetic retinopathy.
