Abstract
BACKGROUND: In the world approximately 16 million are affected by RVO. Prevalence rate for BRVO is 0.5% to 2% and for CRVO is 0.1% to 0.2%. About 2/3rd patients are associated with hypertension, 1/3rd with hyperlipidemia and 5% with diabetes mellitus. Hence an early identification and control of underlying risk factors will help to prevent the occurrence of RVO. AIM OF THE STUDY: To evaluate the risk factors affecting visual outcome in patients with retinal vein occlusion attending a tertiary eye care hospital. MATERIAL AND METHODS: Study Design: Bidirectional observational study. Sample Size: 50 patients. Source of Data: A cohort of patients, with retinal vein occlusion, attending Ophthalmology Outpatient Department in Tirunelveli Medical College for a period of One year from December 2017 to January 2019. Inclusion Criteria: 1. All patients with CRVO >30 yrs of age. (Both male & female) 2. All patients with BRVO >30 yrs of age. (Both male & female) 3. All patients with HRVO >30 yrs of age. (Both male & female) Exclusion Criteria: 1. Patients with ocular ischemic syndrome. 2. Patients with arterial occlusive disorders. METHODOLOGY: 50 patients with retinal vein occlusion were enrolled in the study after getting informed written consent.A detailed history, systemic examination, and ocular examination done. Necessary investigations done to determine various risk factors affecting visual outcome in retinal vein occlusion disorders. RESULTS: ◈ Systemic hypertension is the most important risk factor affecting the visual outcome. A good control of blood pressure is important for a favourable visual prognosis. ◈ Hyperlipidemia has a positive correlation with the development of RVO. ◈ Association with diabetes mellitus is not significant. ◈ Smoking, elevated serum homocysteine, elevated ESR, elevated CRP are associated with RVO, but not a significant risk factor. ◈ Ischemic maculopathy on FFA is an indicator of poor visual prognosis. CONCLUSION: Hence, the study concludes that early identification of systemic diseases and their control in retinal vein occlusion patients, results in good visual outcome.
