One of the most common forms of visual impairment and reduction in overall visual acuity is branch retinal vein occlusion (BRVO), second only to diabetic retinopathy (Rogers et al., 2010; Sun et al., 2013). Unlike central retinal vein occlusion (CRVO) which is a similar macular disease, BRVO is extremely more prevalent and generally only affects a smaller portion of the retina (Osborne et al., ...

We present a rare and unusual avulsed vessel in a patient with branch retinal vein occlusion (BRVO). Fundus examination of the right eye showed BRVO and a long avulsed vessel. Fluorescein angiography clearly defined an avulsed vessel communicated directly with an inferotemporal branch retinal vein at the optic disc. The coexistence of BRVO and avulsed vessel is extremely rare, to our knowledge ...

A 41-year-old woman presented with a short history of blurred vision. She had a 6-year history of refractory hypertension which had been treated with a variety of drug regimens. She was found to have bilateral branch retinal vein occlusion. Retinal vein occlusion is a recognised complication of hypertension but simultaneous involvement of both eyes is extremely rare. Following this episode, blo...

PURPOSE To apply M-CHARTS for quantitative measurements of metamorphopsia in eyes with acute branch retinal vein occlusion (BRVO) and to elucidate the pathomorphology that causes metamorphopsia. METHODS This prospective study consisted of 42 consecutive patients (42 eyes) with acute BRVO. Both at baseline and one month after treatment with ranibizumab, metamorphopsia was measured with M-CHART...

I n this issue of Acta, Crafoord et al. (2008) report on sheathotomy in the treatment of branch retinal vein occlusion (BRVO), as did Wrigstad & Algvere (2006) and Shimura et al. (2007) in recent reports in Acta. While Crafoord et al. suggest that sheathotomy may be beneficial, they also point out that it is difficult to distinguish between the effect of the sheathotomy and that of the vitreous...

Branch and hemisphere vein occlusion were produced in rhesus monkeys by argon laser photocoagulation. The following observations were made: (1) Immediately after occlusion there was venous dilatation, delayed filling of the artery, delayed drainage by the occluded vein, and capillary leakage. (2) Two patterns of evolution were identified within the first week. In some animals the fundus changes...

years; range 41-77 years. There were 16 (35.6%) male patients and 29(64.4%) female patients. Thirty-eight (84.4%) patients (40 eyes) had central retinal vein occlusion (CRVO), 7 (15.6%) patients (8 eyes) had branch vein occlusion (BRVO), and 29 (60.4%) eyes (all CRVO) had ischaemic vein occlusion. Twenty-eight (58.3%) eyes were blind, while 18 (37.5%) had visual impairment. Twenty-five (55.6%) ...

BACKGROUND Ocular vascular occlusions following intraocular procedures are a rare complication. We report a case series of patients with retinal vascular occlusions or anterior ischemic optic neuropathy (AION) after anterior and posterior segment surgery and demonstrate possible risk factors. METHODS Observational case series. RESULTS In ten patients, vascular occlusions were observed withi...
