Seventeen patients with central retinal vein occlusion aged 40 or under were reviewed. Ocular involvement was characteristically unilateral, with moderate degrees of retinal haemorrhage, little retinal ischaemia, and a tendency to optic disc swelling. Visual prognosis was good. Follow-up showed that most patients have good general health and no involvement of the fellow eye. There was little ev...

OBJECTIVE The objective of the following study is to determine the incidence of retinal vein occlusion (RVO) and identify the risk factors in RVO in patients presenting to a tertiary hospital in Rivers State. MATERIALS AND METHODS The medical records of consecutive patients with RVO who presented to the retina clinic of the eye Department of University of Port Harcourt Teaching Hospital over ...

PURPOSE To evaluate the efficacy and safety of intravitreal ranibizumab for branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) in daily clinical practice. METHODS A prospective study enrolling all patients diagnosed with BRVO or CRVO who received intravitreal ranibizumab therapy at our department. RESULTS Fifty-seven patients had BRVO and 49 had CRVO. By 12 month...

PURPOSE To report the efficacy of grid photocoagulation combined with intravitreal bevacizumab (IVB) for macular edema recurring after previous IVBs associated with retinal vein occlusion (RVO). METHODS This retrospective study consisted of 19 eyes with branch retinal vein occlusion (BRVO) and nine eyes with central retinal vein occlusion (CRVO), which were treated with grid photocoagulation ...

Central retinal vein occlusion (CRVO) is a retinal vascular disorder that may cause severe visual impairment. When CRVO occurs the venous blood flow is impeded with elevated intraluminal pressure upstream to the occlusion. The increased hydrostatic pressure causes extravasation of fluid to the extracellular space that compromises arterial perfusion inducing retinal hypoxia. This will release va...

PURPOSE To evaluate the usefulness of focal macular electroretinography (fmERG) for evaluation of macular function in eyes with central retinal vein occlusion (CRVO). METHODS fmERG recordings were made prospectively in 24 patients with unilateral CRVO. The amplitudes and latencies of the a-wave, b-wave, and photopic negative response (PhNR) were compared with other biological parameters, incl...

Accepted 9 November 2008 Published Online First 15 December 2008 ABSTRACT Aims: The aim of the study was to evaluate functional and anatomical changes after intravitreal bevacizumab (AvastinH) in eyes with persistent macular oedema secondary to branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO). Methods: Twenty-nine consecutive eyes with macular oedema secondary to BR...

Introduction Retinal vascular obstruction is rare in young patients; however, it is a significant cause of blindness, especially retinal vein occlusion (RVO), the most common acquired retinal vascular pathology in adults(1). RVO is divided in central (CRVO), hemicentral (HRVO) and branch retinal vein occlusion (BRVO). The reported prevalence of RVO is 5.2/1000 for all types, with 4.42 for BRVO ...

AIM To determine whether a newly identified thrombophilia factor, activated factor VII (FVIIa), is associated with retinal vein occlusion (RVO). METHODS 54 consecutive cases with RVO seen between March and September 1999 were included in the study. 22 cases had central retinal vein occlusion (CRVO) and 32 had branch retinal vein occlusion (BRVO). Ophthalmoscopic examination with detailed medi...

Purpose. To describe a patient with two episodes of deep venous thrombosis and factor V Leiden mutation who presented with central retinal vein occlusion (CRVO) despite prophylactic use of warfarin sodium (Coumadin). Methods. A case report of a 44-year-old woman with a history of recurrent deep venous thrombosis and Factor V Leiden mutation was placed on lifelong prophylactic therapy with warfa...
