[Occlusion of the central retinal vein in young adults: risk factors and visual prognosis].

Retrospective study of 15 cases of central retinal vein occlusion in young patients. A research for risk factors was performed. 4 patients had a systemic disease, and 6 had thrombophilic hematological conditions like blood hyperviscosity and increased platelet aggregation. No inflammatory disease was found. The visual prognosis was good in 7 out of 12 patients with a follow-up of more than 3 months. Chronic macular edema and neovascular glaucoma were responsible for the bad visual prognosis in 5 cases.
