Purpose: A study of various ocular & systemic risk factors in Retinal Vein Occulation (RVO) at Tertiary Eye Care Centre. Methods: A prospective study included 50 eyes of 50 patients, in period of September 2010 to August 2012.INCLUSION CRITERIA: 1.Age>25years, 2. All newly diagnosed cases of Vein Occlusion. EXCLUSION CRITERIA: 1) Age<25years 2) All other ocular diseases causing significant visual impairment. A detailed history, ophthalmic & systemic examinations with all necessary investigations- as and when required were done. Results: In our study, RVOs were more common in males-26(52%) & in 56-65 years of age group -16(32%). BRVOs were more common than CRVO- Nonischemic (26%)>Ischemic (24%). In risk factors –most common was hypertension –in 38(76%) patients. Followed by descending order, Hyperlipidemia 27 (54%)> Diabetes Malitus16 (32%)> Tobacco14 (28%)>HyperHomocystinemia4 (8%)> severe Alcohol2 (4%).The complications were more in Ischemic than Nonischemic-CRVO>BRVO-they were Macular edema 43(86%)>Neovascularization at Iris-14(28%)> Neovascularization at Angle-10(20%)> Neovascular Glaucoma-4(8%). Conclusions: RVOs are more common with increasing Age, in Males & most common risk factor is Hypertensive. Most common cause for vision loss is Macular Edema- Ischemic>Non-Ischemic.
