Retinopathy is a general term for damage to the retina, the light-sensitive tissue at the back of the eye. This damage can manifest in various ways and is often caused by underlying systemic diseases or other ocular conditions. The retina's delicate network of blood vessels is particularly vulnerable to changes in blood sugar levels, blood pressure, or inflammation.

Diabetic retinopathy is one of the most common types, occurring in people with diabetes. High blood sugar levels can damage the small blood vessels in the retina, causing them to leak fluid, bleed, or close off. This can lead to the growth of abnormal new blood vessels, which are fragile and prone to bleeding. Symptoms may include blurred vision, floaters, and dark or empty spots in vision.

Hypertensive retinopathy is caused by high blood pressure. Sustained high blood pressure can damage the retinal blood vessels, leading to narrowing, leakage, or even rupture. This can result in vision changes ranging from mild blurring to significant vision loss.

Other forms of retinopathy include retinopathy of prematurity (ROP), which affects premature infants, and sickle cell retinopathy, associated with sickle cell disease. Each type has specific causes and mechanisms of damage, but all can potentially lead to impaired vision and blindness if left untreated. Early detection and management of the underlying condition are crucial for preventing or slowing the progression of retinopathy. Regular eye examinations are recommended for individuals at risk.
