Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and- second only to diabetic retinopathy as the most common retinal vascular cause of visu...

   Introduction: Retinal vein occlusion  is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).  Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

introduction : laser therapy prevents complications of proliferative diabetic retinopathy (pdr), central retinal vein occlusion (crvo) and branch retinal vein occlusion (brvr), but its effect on visual acuity is controversial. this study evaluated the effect of laser on visual acuity in these patients. materials and methods: this interventional study conducted before–after treatment and evaluat...

RETINAL detachment or the appearance of retinal cysts after the occlusion of large retinal vessels has rarely been described in the literature, although Duke-Elder (1940) mentioned cystic degeneration as invariably following obstruction of the central retinal vein. Norn (1961) described a case of a central retinal cyst which followed a thrombosis of the central retinal vein. Arques (1960) repor...
