What is a major risk factor associated with the development of retinal artery occlusion?

High blood pressure, or hypertension, is a well-established major risk factor for retinal artery occlusion. This condition occurs when the blood flow to the retina is obstructed, often leading to sudden vision loss. Hypertension can damage the blood vessels, making them more prone to clotting, which is a significant mechanism behind retinal artery occlusion. When blood pressure is elevated, there is increased strain on the vascular system, contributing to the development of atherosclerosis or the formation of blood clots.

In contrast, while excessive screen time, lack of physical activity, and hypertension primarily in young adults may have some correlation with overall health and well-being, they do not carry the same level of direct risk for retinal artery occlusion as systemic hypertension does. Excessive screen time can lead to digital eye strain, but it has not been linked to arterial occlusion. Similarly, a sedentary lifestyle can contribute to various health problems, including hypertension and cardiovascular disease, but it is not a primary risk factor specifically for retinal artery occlusion.
