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 transthoracic...

purpose: to evaluate total plasma homocysteine level during the acute phase of central retinal vein occlusion (crvo) compared with a matched healthy group in iranian population, and determine whether hyperhomocysteinemia is also a risk factor for crvo. methods: a study group contains 54 patients presenting with crvo in recent one month, acute phase of the decease, was compared for fasting total...

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 vein occlusion is one of the vascular disorders affecting vision. Branch retinal vein occlusion and central retinal vein occlusion are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and is second only to diabetic retinopathy as the most common retinal vascular cause of visual impairment. The origin of b...

introduction: there are two basic types of vein occlusion, branch retinal vein occlusion (brvo), in which one of the branches of the main vein is blocked, and central retinal vein occlusion (crvo) in which the main vein of the eye is blocked.  vein occlusions are associated with various illnesses and often occur in elderly. the etiological causes of these diseases in the young people remained c...

purpose: to assess the effectiveness of intravitreal injection of triamcinolone acetonide on macular edema associated with branch retinal vein occlusion (brvo). design: a prospective noncomparative interventional case series. patients & methods: fourteen eyes of 14 patients with macular edema associated with brvo were enrolled. in all patients after thorough ophthalmic examination, 4 mg triamci...

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...

A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...

purpose : to evaluate the effectiveness of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography in macular edema associated with nonischemic central retinal vein occlusion (crvo). design : a prospective interventional case series. patients & methods : twenty eyes of 25 patients with nonischemic crvo and macular edema with visual acuity o...

OBJECTIVES To describe the 15-year incidence of retinal vein occlusion (central retinal vein occlusion and branch retinal vein occlusion) and associated risk factors. METHODS A population-based study where branch retinal vein occlusion and central retinal vein occlusion were detected at baseline (n = 4068, 1988-1990) and three 5-year follow-up examinations by grading 30 degrees color fundus p...
