Diabetic retinopathy is a complication of diabetes affecting the eyes. It occurs when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Over time, these damaged blood vessels can leak fluid or bleed, causing vision problems and potential blindness if left untreated.
Initially, diabetic retinopathy might not show any symptoms. As it progresses, symptoms can include blurred or distorted vision, floaters (spots or dark strings in vision), impaired color vision, and eventually, vision loss.
Managing blood sugar levels through proper diabetes management, regular eye exams, and, in more advanced cases, treatments like laser surgery, injections, or vitrectomy can help prevent or slow the progression of diabetic retinopathy.« Back to Glossary Index
