Diagnosis

Characteristics of diabetic retinopathy can be detected with an ophthalmoscope during a dilated eye examination. Adults over 30 who have diabetes should have an annual dilated eye beginning at diagnosis. People who are diagnosed with diabetes before age 30 and have had the disease at least five years should also have a yearly eye exam. Once retinopathy develops, more frequent exams may be necessary.
A test called fluorescein angiography, which involves the injection of dye into blood vessels in the arm followed by a series of photographs of the back of the eye, may be needed to stage the disorder and guide treatment.
