Most people are surprised to learn that early signs of serious medical conditions affecting your body can be detected in the eyes. Heart disease, diabetes, cancer, high blood pressure, multiple sclerosis, autoimmune diseases, sexually transmitted diseases, and even Alzheimer’s disease can be detected in the eye. That’s because the blood vessels and nerves in our eyes are reflective of the state of the rest of the body. A routine eye exam can do more than save your eyesight, it can also save your life.

Take for example Barbara Krupar, a 65-year-old retiree from Ohio who went to her ophthalmologist after experiencing some disturbing changes in her vision. When Nicole Bajic, MD, examined her, she detected possible early warning signs of a stroke, and recommended Barbara go to the emergency room immediately to have her head and neck imaged. The ER physician determined that the carotid artery in her neck was 85 percent blocked. She was at imminent risk of suffering a stroke. The exam likely saved her life.
