Description
Disease characterized by decreased visual acuity resulting from venous occlusion of any etiology
Etiology
Etiology
- Ischemic CRVO:
- 20–25% of cases
- Blocked venous return leads to backflow in capillaries, hemorrhage, and macular edema.
- Limited space at lamina cribrosa predisposes to thrombosis due to slow flow and vessel wall changes
- Theorize that arteriosclerotic changes in the adjacent artery may impinge upon the vein.
- Blood viscosity also thought to play a role
- Nonischemic CRVO:
- Milder, incomplete occlusion
