How does diabetic retinopathy cause vision loss?
Frequently Asked Questions About Eye ConditionsFragile, abnormal blood vessels can develop and leak blood into the center of the eye, blurring vision. This is proliferative retinopathy and is the fourth and most advanced stage of the disease. Fluid can leak into the center of the macula, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This condition is called macular edema.
Related QuestionsI had laser treatment because of my diabetic retinopathy, but my vision is still blurry. Why?
Frequently Asked Questions - Retina Vitreous Center PA - Oph...Focal laser treatment of diabetic macular edema is best performed before central vision is affected. Once the center of the macula is swollen, laser often results in some improvement, but the vision may be permanently impaired to some degree. This is why regular retinal exams are important. Additionally, poor blood flow (ischemia) in the macula often damages the vision. There is no treatment for macular ischemia.

Related QuestionsWhat are the different types of diabetic retinopathy?
Diabetic Retinopathy FAQ - AllAboutVision.comDiabetic retinopathy is classified as either nonproliferative (background) or proliferative. Nonproliferative retinopathy is the early stage, where small retinal blood vessels break and leak. In proliferative retinopathy, new blood vessels grow abnormally within the retina. This new growth can cause scarring or retinal detachment, which can lead to vision loss. The new blood vessels may also grow or bleed into the vitreous humor, the transparent gel filling the eyeball in front of the retina.

General Frequently Asked Questions Fromer Eye Centers Catara...Diabetic retinopathy is a complication of diabetes that weakens the blood vessels that supply nourishment to the retina (the light-sensitive lining in the back of the eye where vision is focused). When these weak vessels leak, swell or develop thin branches, vision loss occurs. In its advanced stages, the disease can cause blurred or cloudy vision, floaters and blind spots – and, eventually, blindness. This damage is irreversible.Related Questions

FAQ | Newman and Taub Vision Center - Your resource for Dall...Diabetic retinopathy is a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina. In some people with diabetic retinopathy, retinal blood vessels may swell and leak fluid, while in others, abnormal new blood vessels grow on the surface of the retina. These abnormal vessels can bleed causing vision loss from scarring and retinal detachment. Diabetic retinopathy cannot be completely avoided, but the risk can be greatly reduced.Related Questions
FAQ's on Diabetic Eye DiseaseThe part of the eye most commonly affected by diabetes is the retina. Because of blood vessel damage, the retinal circulation becomes compromised leading to a cascade of events that destroy the retina and vision. The earliest stage of diabetic retinopathy is the "non-proliferative" stage, with the formation of microaneurysms and tiny hemorrhages in the retinal tissue. At this level, there is usually no noticeable visual change.Related Questions
