Sudden Vision Loss? It Could Be an Eye Stroke

An eye stroke, medically known as retinal artery or vein occlusion, is a critical condition where the retina's blood supply is obstructed. This blockage deprives retinal cells of vital oxygen and nutrients, potentially causing rapid and irreversible vision loss. Retinal occlusion is categorized into two main types: Retinal Artery Occlusion (RAO), affecting blood supply to the retina, and Retinal Vein Occlusion (RVO), where blood drainage is impaired. Symptoms are typically sudden and painless, including blurred vision, dark spots, or a shadowed visual field.

Risk factors for eye strokes include high blood pressure, diabetes, high cholesterol, heart disease, smoking, and age over 50. The blockage often results from a blood clot or plaque buildup. Immediate medical attention is vital for managing an eye stroke. Treatment focuses on restoring blood flow and addressing underlying causes to prevent further incidents. Long-term eye health is supported by managing chronic conditions, maintaining a heart-healthy diet, avoiding smoking, and staying physically active.
