³S.B. Ankara Ulucanlar Göz Eğitim ve Araştırma Hast., 2. Göz Kliniği, Ankara, Doç. Dr. Purpose: To investigate etiology, age, gender, follow-up time, accompanying eye examination findings, and outcomes of treatments in cases with branch retinal vein occlusion.
Material and Methods: Eighty four eyes of 78 patients with branch retinal vein occlusion that were followed-up in Turkish Ministry of Health Ankara Ulucanlar Eye Education and Research Hospital Retina Clinic between 2008 and 2010 were retrospectively evaluated in this study. A complete ophthalmological examination including visual acuity, intraocular pressure with applanation tonometry, biomicroscobic examination findings, dilated pupil examination of the posterior segment, optic coherence tomography, and fluorescein angiography were evaluated at baseline and during follow-up period.
Results: There were 40 male (51.2%) and 38 female (48.8%). The average age of patients was 61.1 years (35-83 years). Mean follow up period was 7.9 months (6-24 months). Eighty four eyes of 78 patients were involved. Nine patients (11.6%) had bilateral involvement. Hypertension in 47 eyes (55.9%), diabetes mellitus in 15 eyes (17.9%), cardiovascular disease in 4 eyes (4.7%), hematologic problems in 3 eyes (3.6 %), and vasculitis in 1 eye (1.2%) were detected as etiologic causes. No causes were found in 14 eyes (16.7%). Argon laser photocoagulation alone in 27 eyes (32.1%), intravitreal triamcinolone injection with argon laser photocoagulation in 15 eyes (17.9%), intravitreal triamcinolone injection alone in 8 eyes (9.5%), intravitreal bevacizumab injection with argon laser photocoagulation in 7 eyes (8.3%), intravitreal bevacizumab injection alone in 3 eyes (3.6%), intravitreal bevacizumab and intravitreal triamcinolone injection with argon laser photocoagulation in 2 eyes (2.4%) were used. Twenty two eyes (26.2%) followed without treatment.
Conclusion: Based on the results that were obtained in this series, hypertension was the most common cause in cases with branch retinal vein occlusion. Unilateral involvement was seen in these cases in general. There is an affirmative effect of the argon laser photocaoagulation and intravitreal drug injection to the prognosis in selected cases.
