What is the most common cause of retinopathy?

The most common cause of retinopathy is diabetes. Diabetic retinopathy occurs when high blood sugar levels damage the blood vessels in the retina, which is the light-sensitive tissue at the back of the eye. Over time, these damaged blood vessels can leak fluid or bleed, leading to vision impairment. Diabetes can cause changes in the retina even before other symptoms appear, making it a significant concern for individuals with long-standing or poorly controlled diabetes.

While high blood pressure, genetic factors, and aging can also contribute to various forms of retinopathy or eye issues, diabetic retinopathy is specifically the most prevalent type, particularly in the context of chronic disease management. Individuals with diabetes are regularly monitored for this condition as part of their overall health care.
