Diabetic retinopathy is a serious eye condition and a leading cause of vision loss in people with diabetes. It occurs when the tiny blood vessels in the retina become damaged from high levels of blood sugar. Symptoms of diabetic retinopathy can include blurred vision, difficulty seeing colors, floaters, and loss of vision. Diagnosis of diabetic retinopathy usually involves a comprehensive eye exam, including dilation of the pupils, ultrasound and optical coherence tomography (OCT). Treatment options for diabetic retinopathy can include laser surgery, injection of medications, and more advanced treatments such as vitrectomy. Early diagnosis and treatment are the key to preventing vision loss due to diabetic retinopathy.
