Hemi-central retinal vein occlusion

Abstract

Hemi-central retinal vein occlusion (hemi-CRVO) is a retinal vascular accident that involves venous drainage from approximately one-half of the retina and often occurs as a result of a systemic disease. Hemi-CRVO can manifest one of two types: ischemic or nonischemic. Two major complications associated with this disease are macular edema and neovascular glaucoma. Though, at this time, treatment of central retinal vein occlusion is controversial, management of the underlying systemic disease is imperative. This paper presents a case of hemi-CRVO and discusses various clinical aspects of the disorder including predisposing factors, diagnosis, and management. © 1993.
