The prevalence of primary open angle glaucoma (POAG), male sex, laterality, fellow eye involvement, smoking, and hypertension in the five subgroups of retinal venous occlusion (RVO) classified according to the site of occlusion. The proportions were compared among four subgroups (NS-RVO excluded) using the χ2 test. No = number of cases; AV-RVO, arteriovenous crossing RVO; OC-RVO, optic cup RVO; NONHS-RVO, optic nerve sited RVO without ONHS; ONHS-RVO, optic nerve sited RVO with ONHS; NS-RVO, “No site” RVO.
