Central Retinal Vein Occlusion: An Overview
Central Retinal Vein Occlusion (CRVO) is a significant retinal vascular disorder characterized by the blockage of the main vein responsible for draining blood from the retina. This condition can lead to sudden, painless vision loss and is a major cause of visual impairment, particularly in older adults.

This blockage is often due to a thrombus (blood clot) and can be influenced by several factors, including vessel damage, venous stasis, and hypercoagulability, collectively known as Virchow’s triad.
