What Is Diabetic Eye Care for Seniors?
Diabetes threatens vision through several eye complications. Understanding diabetic eye care helps seniors with diabetes protect their sight through prevention and early treatment.
How Diabetes Affects Eyes
Diabetic retinopathy damages blood vessels in the retina. High blood sugar weakens vessel walls. Vessels leak fluid or bleed, and abnormal new vessels may grow. This progressive damage threatens vision.
Diabetic retinopathy is the leading cause of blindness in working-age adults. Seniors with long-standing diabetes have high rates. Early stages have no symptoms, making screening essential.
Diabetes increases cataract risk. Cataracts develop earlier and progress faster in diabetics. Clouding of the lens impairs vision but is treatable with surgery.
Glaucoma risk increases with diabetes. Pressure buildup damages the optic nerve. Diabetics have double the glaucoma risk of non-diabetics.
Diabetic macular edema occurs when fluid leaks into the macula, the central vision area. Swelling causes blurred central vision. This can occur at any stage of diabetic retinopathy.
Risk Factors for Diabetic Eye Disease
Duration of diabetes matters most. The longer you have diabetes, the higher the risk. Most people with diabetes for 20 years have some retinopathy.
Blood sugar control affects eye disease. Higher average blood sugars increase risk. Tight control reduces development and progression of retinopathy.
Blood pressure and cholesterol contribute. Controlling these cardiovascular risk factors protects eyes as well as heart.
Pregnancy can worsen diabetic retinopathy. Pregnant diabetics need more frequent eye examinations.
Screening and Prevention
Annual dilated eye exams are essential for all diabetics. Examination detects retinopathy before symptoms develop. Early detection enables treatment before vision loss.
Medicare covers annual diabetic eye exams. This preventive benefit costs beneficiaries nothing. There is no excuse to skip screening.
Blood sugar control is the most important prevention. Keeping A1C levels in target range significantly reduces retinopathy risk and progression.
Blood pressure and cholesterol control protect eyes. Managing cardiovascular risk factors benefits vision.
Treatment
Laser treatment seals leaking vessels and destroys abnormal growth. Multiple sessions may be needed. Laser treatment preserves vision but cannot restore already lost sight.
Anti-VEGF injections reduce abnormal vessel growth and leakage. Medications injected into the eye control diabetic macular edema and proliferative retinopathy. Ongoing treatment may be needed.
Vitrectomy surgery removes blood from the eye and treats advanced retinopathy. This may be needed when bleeding does not clear or when scar tissue threatens the retina.
