Almost all patients with glaucoma have no symptoms until the late stages of the disease. Thus glaucoma can only be detected by regular eye examinations, and it remains a leading cause of blindness in the U.S. because of its insidious nature. However, most patients diagnosed with glaucoma can be treated with eyedrops alone to prevent vision loss.
MACULAR DEGENERATION is the leading cause of blindness in people over age 65. It affects approximately 10% of senior adults, but fortunately the great majority of those with macular degeneration have the milder form of the disease, which usually does not cause substantial loss of vision.
DIABETIC RETINOPATHY Diabetes can damage the eye in several ways, and diabetic retinopathy often occurs without any symptoms in its early stages. Everyone with diabetes should have a complete eye exam at least once a year, because if diagnosed and treated early enough, the great majority of visual loss from diabetes can be prevented.
