Major risk factor is hypertension 20(40%), Diabetes alone is a risk factor in 14% followed by Dyslipidemia, CAD and CVA.

Conclusion: The incidence of RVO is more in the age group of 61-70yrs(48%).Study shows male preponderance(64%)and females(36%).Incidence of CRVO 32%,HRVO 8%,BRVO 60%.Greater risk factor association is with HTN,DM,Hyperlipidemia and glaucoma.Age is an independent risk factor.
