Diabetic eye disease is a group of eye problems that can be caused by diabetes, including diabetic retinopathy [REH-tin-AH-puh-THEE], macular edema [MAH-kyoo-LUHR uh-DEE-muh], cataracts [KAT-uh-rakts], and glaucoma [glaw-KO-muh]. These conditions can cause vision problems or blindness, so it’s important to keep your diabetes under control and get regular eye exams to look for problems.
