Symptoms of the disease range from no symptoms to blindness. Blurry vision is the most common symptom of diabetic retinopathy. It is our goal to examine and diagnose patients with diabetic retinopathy before symptoms develop.
Blurry vision results from abnormal accumulation of fluid in the macula, the functional center of the retina. With time, the normal blood vessels of the retina become leaky. Fluid leaches out of the normal retinal blood vessels and pools in the retina. When fluid accumulates in the macula, called diabetic macular edema, the vision becomes blurred. The more leakage and fluid accumulation, the blurrier the vision.
Advanced diabetic retinopathy can be associated with floaters. Bleeding into the vitreous, called a vitreous hemorrhage, can occur in cases of proliferative diabetic retinopathy, the advanced stage of the disease that may cause blindness.
