purpose: to determine the frequency of risk factors for retinal vein occlusion (rvo) in patients referred to a private clinic in rasht during 1995-2001. methods: this cross-sectional study was conducted on all patients with rvo who were referred to the clinic. sex, age, hypertension (htn), cardiovascular diseases (cvd), diabetes mellitus (dm), hypercoagulable states, glaucoma, smoking, hyperlip...

purpose: to investigate aqueous humor nitric oxide (no) levels in patients with branch retinal vein occlusion (brvo) and central retinal vein occlusion (crvo) and to compare these with age-matched controls. methods: eight consecutive patients with brvo and 16 patients with crvo were included in this study. aqueous humor specimens were obtained within 21 days of diagnosis. samples of aqueous hum...

data suggest that the multifocal electroretinography (mferg) may have a role in the assessment of patients with central retinal vein occlusion (crvo). to explore the mferg responses in patients with crvo. mferg responses were recorded at 61 discrete retinal locations from both eyes of 25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. the latencies and amplitudes of ave...

central retinal vein occlusion (crvo) is the third most common blinding vascular retinal disorder. as there is no proven treatment for crvo, we performed this study to evaluate the effectiveness of radial optic neurotomy (ron) on visual acuity in eyes with crvo. this study was designed as an interventional case series. pars plana vitrectomy with ron was performed in 18 eyes of 16 patients with ...

purpose: to compare repeated intravitreal injections of bevacizumab (ivb) with triamcinolone acetonide (ivt) for treatment of acute branch retinal vein occlusion (brvo). methods: this randomized clinical trial included, 86 eyes with recent onset (less than 12 weeks) brvo. participants were randomly assigned to two treatment groups: the ivb group (43 eyes) consisted of patients who received mont...

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...

uncontrolled hypertension is well- known to give rise to systemic complications involving multiple central organs. artherosclerosis leads to damage of the retinal vessels wall, contributing to venous stasis, thrombosis and finally, occlusion. retinal vein occlusions compromise vision through development of ischaemic maculopathy, macular oedema, and rubeotic glaucoma. laser photocoagulation rema...

   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...

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...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...
