| Aims: To investigate the subtypes of branch retinal vein occlusion (BRVO) and study the prevalence of systemic disorders associated with each subtype. Settings and design: An observational retrospective study conducted from 2017 to 2019. Methods and material: The study included patients with BRVO of different subtypes (superotemporal, inferotemporal, macular, and nasal BRVO). Data collected from the patients included age, sex, laterality of the affected eye, and history of medical diseases. The patients were thoroughly examined, and fundus fluorescein angiography and spectral domain optical coherence tomography were performed. All data were statistically analysed using SPSS software. Results: Eighty-one eyes of 78 patients were included in this study. Superotemporal BRVO was observed in 28 eyes (34.6%), inferotemporal BRVO was observed in 27 eyes (33.31%), and macular BRVO was observed in the remaining 25 eyes (30.9%). There were 13 (46.4%), 14 (51.9%), and 11 (44%) men in the superotemporal, inferotemporal, and macular BRVO groups, respectively (P= 0.843). Overall, 10 (35.7%), 15 (55.6 %), and 11 (44%) right eyes were affected in the superotemporal, inferotemporal, and macular BRVO groups, respectively (P= 0.569). Macular edema occurred in 23 (82.1%), 23 (85.2%), and 22 (88%) patients in the superotemporal, inferotemporal, and macular BRVO groups, respectively (P= 0.837). Conclusions: Superotemporal, inferotemporal, and macular BRVO are common subtypes of BRVO, and all have similar risk factors, regardless of sex or eye preference. | ||||
