Patients and Methods: Sixty-six eyes of 65 patients diagnosed as RVO in our clinic between January 2002 and April 2003 were involved. All cases underwent a detailed ophthalmological examination including fundus fluorescein angiography (FFA). Detailed medical history from every patient was obtained and necessary consultations to detect possible risk factors were required. Visual acuity at presentation and last control, treatment and follow-up period were recorded.
Results: Out of 65 patients with RVO, 36 (55.4%) were female and 29 (44.6%) were male with an average age of 61.6 years. 38 eyes (57.5%) had branch retinal vein occlusion (BRVO), 20 (30.3%) had central RVO, 5 (7.6%) had hemispheric RVO and 3 (4.6%) had macular RVO. The most common BRVO type was upper temporal BRVO and the most common risk factor was hypertension. When all eyes with RVO were grouped into two as central and branch RVO and visual prognosis was investigated, visual acuity was observed to increase in branch RVO group while vision decreased in central RVO group with follow-up.
Conclusion: RVO is generally observed in older age group and is associated with systemic disorders, primarily with hypertension. Among our cases, upper temporal BRVO was the most common type of RVO.
