Baseline Characteristics and Risk Factors for Retinal Vein Occlusions

ABSTRACT

Introduction: Venous obstructive disease of the retina iscausing significant visual morbidity affecting quality of lifeof patient. Incidence of CRVO is 0.8 per 1000 persons and 4.4per 1000 persons for BRVO. RVO most commonly affects thevenous blood supply of entire retina [CRVO] or a quadrantdrained by one of the branches [BRVO] less commonlysuperior or inferior half of retina alone is affected [HRVO].Study Aimed to study demographic characteristics and riskfactors of Retinal Vein Occlusions (Both CRVO and BRVO)Material and methods: This is a cross sectional observationstudy. It included 208 patients [64 CRVO patients and 144BRVO patients]at Retina department, Sarojini Devi EyeHospital, Hyderabad. Study was conducted for 1 year and 7months.Results: Hypertension stands alone as the most significantrisk factor (P Value is 0.005). Other factors studied likeUrban Background, Lack of physical Activity, Diabetes,Hyperlipidemias, CVA, CAD etc. though were present in goodnumbers in the cases studied but they were not statisticallysignificant.Conclusion: Hypertension, Diabetes and Raised SerumLipids are significant risk factors for Retinal Vein Occlusionsin South Indian population
