“…Jensen observed that the artery lay anterior to the vein at the majority of BRVO crossing sites and postulated that the predilection of BRVO for the superotemporal quadrant was due to the greater number of crossings in this quadrant [ 11 ]. Others have recently confirmed Jensen's observation of a greater percentage of artery-anterior-to-vein crossings at the BRVO sites [7,19] and of a greater number of crossings in the superotemporal quadrant [8]. A histopathologic study confirmed the importance of the AV crossing at the site of the BRVO [10].…”

Branch retinal vein occlusion (BRVO) is often associated with arteriosclerosis. Typically the occlusion occurs at an arteriovenous crossing. We report a case of a previously healthy patient who developed a BRVO. Funduscopy and fluorescein angiography suggested an intravascular thrombus as the cause of the occlusion. The investigations performed were positive for systemic hypertension and hyperlipidaemia. After 2 months, fundus examination revealed disappearance of the intravascular thrombus, resolution of the macular edema and improvement of thevisual acuity. Certain physiological characteristics of the retinal circulation associated with hyperlipidaemia and systemic hypertension appear to favour thrombus formation.

“…In approximately 60-70% of eyes that are unaffected by BRVO the artery has been reported to be anterior to the vein whereas in 98-99 % of eyes with BRVO it crosses the vein [9][10][11] .…”

“…Increased rigidity of the crossing artery induced by arteriolar sclerosis may increase the risk of occlusion. Studies investigating the vulnerebility of A/V crossing sites to BRVO have reported focal thickening of the venous basement membrane and hyperplasia of extracellular matrix and adventitia at A/V crossings [15][16][17][18][19] .…”

Retinal vein occlusion (RVO) is the second most common vascular disease after diabetic retinopathy. Although its high frequency, mechanisms underlying RVO and optimal treatment strategies are still controversial. There are various treatment modalities for retinal vein occlusion including observation, systemic treatments, intravitreal agents, laser photocoagulation, fibrinolytic treatment and surgical approaches. Despite most of the treatment strategies are directed at secondary complications of RVO that affect vision including macular edema and retinal neovascularization, some treatment options also have the ability to create a bypass around the obstructed retinal vein and to decrease the raised venous hydrostatic pressure. The aim of this review is to describe the outcomes of fibrinolytic and surgical treatment modalities for RVO.
