Retinal Vein Occlusions (RVOs)

Branch Retinal Vein Occlusion (BRVO) occurs when one of the small branches of the retinal vein gets blocked. The pressure caused by the blockage of blood flow through these small branches leads to small retinal hemorrhages, swelling, and other damage around the site of the blockage. If not treated soon, the retina will be deprived of oxygen and nutrients leading to loss of vision in the affected area.

Central Retinal Vein Occlusion (CRVO) occurs when the central vein of the retina is blocked. CRVOs are generally grouped into two categories: ischemic and non-ischemic. Ischemic CRVOs are more serious than non-ischemic CRVOs. The ischemic form can produce other complications in other areas of the eye as well as the retina. Non-Ischemic CRVOs usually have a better visual prognosis than the ischemic form, however, there is still the possibility of the non-ischemic form turning into the ischemic form. CRVOs may produce a sudden painless loss of vision in the affected eye.

Factors contributing to an RVO :

High blood pressure

Diabetes

Chronic Open-angle glaucoma

Atherosclerosis

Thrombus

Syphilis

Lymphoma

Leukemia

Multiple myeloma
