“…2,9,12,28 In our study group, about 10% patients had ocular hypertension which is not significant with actual 90% CI and considered it not to be a risk factor. 3,9,11,12 In our study group in 40% shorter axial length was found with a mean axial length of 22.41 mm. 29 Various studies have suggested that eyes with shorter axial length have a smaller disc and a narrower sclera canal, hence retinal vessels are enclosed within a limited space.…”

“…These findings are in conformity with study done by many authors. 3,5,9,[16][17][18][19] In our study we noted that out of 100 patients 80 were males (80%) and 20 (20%) were female patients. Our study on BRVO showed male preponderance which is in concordance with the study done by Jhonson et al, Rath et al as they reported higher rates in males.…”

“…5,13,17,[20][21][22][23][24] Association of diabetes and BRVO was observed in 10% which is similar to other studies conducted elsewhere. 2,3,5,9,12,28 It was noted that 38% of patients in the study group had a deranged lipid profile which is significant with actual 90% CI. This is in accordance with Blue mountain eye study which had reported hyperlipidaemia was an important associated systemic condition contributing 35% of cases.…”

“…Branch retinal vein occlusion (BRVO) is around three times more prevalent than central retinal vein occlusion and the fifth most frequent cause of blindness. [2][3][4] A western Australian report estimates that annual incidence of blindness due to BRVO is 0.41 %. 5 RVO is an obstruction of the retinal venous system by a thrombus, vasculitis or by the external compression of the vein wall and the most common region of BRVO is at the arteriovenous crossing where the artery and vein share a common adventitial sheath.…”

INTRODUCTIONRVO has been recognized as a distinct entity described as "retinal apoplexy, by Leibreich in 1854 and "haemorrhagic retinitis" by Leber in 1877. 1 Retinal vein occlusions (RVO) are the second commonest cause of reduced vision amongst retinal vascular diseases. Branch retinal vein occlusion (BRVO) is around three times more prevalent than central retinal vein occlusion and the fifth most frequent cause of blindness.2-4 A western Australian report estimates that annual incidence of blindness due to BRVO is 0.41 %. 5RVO is an obstruction of the retinal venous system by a thrombus, vasculitis or by the external compression of the vein wall and the most common region of BRVO is at the arteriovenous crossing where the artery and vein share a common adventitial sheath. 6,7 BRVO typically occurs in the middle aged and elderly patients (>50 yrs) with male predominance. [8][9][10][11][12] The predominant risk factors are cardiovascular diseases, diabetes, primary glaucoma and hyperlipidaemia. [7][8][9][10][11] Hypertension being the predominant risk factor among cardiovascular diseases. Neither high body mass index nor use of oestrogen or birth control pills showed any significant association with BRVO. 13,14 On Pubmed search it was found that there is paucity of Indian data regarding demographic characteristics, ABSTRACTBackground: 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.

“…In a study conducted in central India, RVOs were detected in 0.8% of the adults examined, with branch vein occlusions being approximately seven times more common than central vein occlusions [2].There are two variants: non-ischemic and ischemic [3]. The causes for visual loss are macular edema and ischemia.…”

Purpose: To study the efficacy and safety of Posterior SubTenon Triamcinolone acetonide (PSTT) in the treatment of macular edema in retinal vein occlusions. The efficacy is studied by anatomical and visual improvements. Methods: This study was a prospective interventional case series. 24 eyes of 24 patients (13 male and 11 female) with recent onset non-ischemic RVO (Retinal Vein Occlusion) underwent Posterior Sub-Tenon Triamcinolone (PSTT). Of the 24 eyes treated, 18 eyes were of BRVO (Branch Retinal Vein Occlusion) and 6 were CRVO (Central Retinal Vein Occlusion). All the eyes received 40 mg of Triamcinolone Acetonide (TA) in 1ml through posterior sub-tenon route. All the eyes were examined at baseline and after four weeks of being injected with TA. Changes in the best corrected visual acuity {letters of ETDRS (Early Treatment Diabetic Retinopathy Study) chart} and Central Macular Thickness (CMT) were studied. A gain of more than 5 letters was considered as effective. The eyes were examined for raised IOP (Intra-Ocular Pressure) and other complications.Results: Out of the 24 eyes 19 (79%) showed an improvement of more than 5 letters after a month of treatment. All the patients exhibited a certain degree of decrease in CMT. The mean BCVA increased from 30.08±10.16 to 40.21±8.93 (p<0.05). The mean CMT decreased from 575.08±131.55 to 282.08±163.99 (p<0.05).
