“…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]. In our case, we observed, at the site of the occlusion, an intravascular white material occluding the vessel's lumen without any sign of ocular inflammation.…”

“…The occlusion invariably appears to occur at an arteriovenous (AV) crossing point [9,10]; thickening of the arterial wall and the presence of a common adventitia of the artery and the vein at AV crossings seem to play a role in the pathogenesis of the BRVO [10,16], The major risk factor is arteriosclerosis (age, systemic hypertension, diabetes mellitus, smoking, hyperlipidaemia). Other predisposing factors, such as blood dyscrasias, lympho-proliferative disorders, periphlebitis (sarcoidosis, Behcet's disease, retinal infections), hyperopia and open-angle glaucoma have been described [1-3, 12, 15, 17].…”

“…Frangieh et al demonstraram, através de estudos histopatológicos, a presença de trombos no local da oclusão em oito pacientes com obstrução venosa retiniana, com conseqüente esclerose moderada a grave em quase todas as arteríolas envolvidas (5) .…”

“…Frangieh et al demonstraram, através de estudos histopatológicos, a presença de trombos no local da oclusão em oito pacientes com obstrução venosa retiniana, com conseqüente esclerose moderada a grave em quase todas as arteríolas envolvidas (5) . As oclusões de ramo da veia central da retina ocorrem no setor temporal em 98% dos casos, e 66% destes acometem a arcada temporal superior (4) .…”
