Risk Factors of Branch Retinal Vein Occlusion

Aims and Objective - The aim of the present study is to identify risk factors associated with different retinal vascular occlusive diseases (RVOD), such as central retinal artery occlusion (CRAO), hemi-retinal artery occlusion (HRAO), branch retinal artery occlusion (BRAO), cilioretinal artery occlusion (Cilio-RAO), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and hemi-retinal vein occlusion (HRVO). Patients and Method - A cross-sectional study on 114 consecutive subjects, aged 24-96 years who have attended at the outpatient department of ophthalmology at Shyam Shah Medical College, Rewa, MP, were included in the study. The Duration of study was January 2016 to December 2017. Only patients with CRAO, BRAO, HRAO, Cilio-RAO, CRVO, BRVO, and HRVO were included in the study. Other retinal vascular disorders such as diabetic vaso-occlusive disease, anterior and posterior ischemic and non-ischemic neuropathy, hypertensive retinopathy, sickle cell retinopathy, retinal telangiectasia, retinopathy of prematurity, were excluded from study. Results - We have included 114 patients, 64 cases (56.14%) males, 50 (43.85%) females, aged 56+/-8 years (range 24-96 years). Bilateral retinal vascular occlusive disorders were seen in only 4 cases (3.5%). Two patients have bilateral CRVO followed by one case of bilateral BRVO and one case of bilateral CRAO. Out of 114 patients, branch retinal vein occlusion was seen in 62 cases (54.38%), followed by central retinal vein occlusion in 36 cases (31.57%), CRAO in 8 cases (7.01%), and hemi- retinal vein occlusion in 4 cases (3.50%). Hypertension was the most common, (40 cases, 35.08%) risk factor identified for retinal vascular occlusive disorders followed by diabetes 24 cases (21.05%), combined diabetes and hypertension in 22 cases (19.29%), and atherosclerosis in 18 cases (15.78%). Conclusions - Retinal vascular occlusive diseases have systemic as well as ocular risk factors. Understanding of these risk factors is essential for proper treatment of RVOD. Timely identification of risk factors for RVOD may helpful in decreasing ocular and systemic morbidity in these patients.

Purpose To describe a case of branch retinal vein occlusion (BRVO) in a patient who tested positive for the 20210 A allele of the prothrombin (PT) gene. Methods A 48-year-old man had visual loss in the right eye secondary to BRVO confirmed by ophthalmoscopy and fluorescein angiography. His medical history was not remarkable for common risk factors for retinal occlusive diseases. Results Laboratory tests for hypercoagulability were positive for PT 20210 A variant. The patient's family tested negative for the PT variant. Conclusions Laboratory tests for coagulopathy, including the PT 20210 A variant, should be added to the examination of patients with central or BRVO, especially if most common risk factors for thrombosis have been excluded.

For years, branch retinal vein occlusion is still a controversial disease in many aspects. An increasing amount of data is available regarding classification, pathogenesis, risk factors, natural history, and therapy of branch retinal vein occlusion. Some of the conclusions may even change our impression of branch retinal vein occlusion. It will be beneficial for our doctors to get a deeper understanding of this disease and improve the treatment skills. The aims of this review is to collect the information above and report new ideas especially from the past a few years.

Vein Occlusion

Background: Many large case series about demographic characteristics and association of branch retinal vein occlusion (BRVO) with systemic diseases have been published in the western population. However this pattern of demographic characteristics in the developed countries may not be representative of epidemiology of disease in the developing countries because of the real paucity of reports from these areas. The study is therefore aimed at evaluating demographic characteristics, to identify the common systemic or ocular risk factors and common clinical presentation of BRVO patients. Methods: Hundred consecutive newly diagnosed cases of BRVO were included in this study. A complete ophthalmic evaluation was done after obtaining informed consent. A complete history both ocular and medical with emphasis on hypertension, diabetes and symptoms concerning glaucoma were taken.Results: Out of 100 patients 80 were males and 20 were females. Average age of total patients was 62. Commonest mode of presentation was diminution of vision in 80 patients followed by floaters in 10 patients. About 10 patients were asymptomatic at the time of presentation. Out of 100 patient 80 were hypertensives, 10 were diabetics and deranged lipid level was found in 38 patients. Raised imtraocular pressure (IOP) was found in 10 patients, shorter axial length in 40 and no other ocular association was found in 50 patients. Conclusions: From this study we conclude that it is a disease of elderly age group and hypertension, hyperlipidaemia, shorter axial length are associated risk factors in patients with BRVO and must be looked for in such cases.
