Diabetic Retinopathy Home A-Z Health Information Health Library A-Z Diabetic Retinopathy Overview Diabetic retinopathy is an eye disorder arising when elevated blood sugar levels cause damage to the blood vessels in the retina. It can result in vision problems and blindness if left untreated. Symptoms Blurred vision, dark spots, and difficulty in seeing colours. Diagnosis Comprehensive eye evaluation, including dilated eye exams and imaging tests. Treatment Depends on the severity and may include laser therapy, injections, or surgery to prevent vision loss. Managing blood sugar levels, cholesterol levels, and blood pressure is the best way to prevent and prolong the progression of diabetic retinopathy. Regular eye exams are crucial for early detection and treatment.If you have diabetes, make sure to have a yearly eye check-up with dilation, even if your vision appears to be normal. If you experience sudden changes related to your vision, for e.g., blurriness, dark spots, or haziness, please contact your ophthalmologist immediately.
