Normal vision vs. Central Retinal Venous Occlusion

Overview


Central Retinal Vein Occlusion (CRVO) is a vascular disorder that affects the eye, particularly the retina. In CRVO, there is a blockage or obstruction in the central retinal vein, which is responsible for carrying deoxygenated blood away from the retina. This blockage can lead to a buildup of pressure in the blood vessels, causing fluid leakage and various complications that can affect vision.



Types of CRVO


CRVO is generally classified into two main types:  


Non-ischemic CRVO

In this form, blood flow to the retina is still partially maintained despite the blockage. While vision loss can occur, it may not be as severe as in ischemic CRVO.  


Ischemic CRVO

This type involves a more severe blockage, leading to a significant reduction in blood flow to the retina. Ischemic CRVO is associated with a higher risk of vision loss and complications.
