INCIDENCE OF RETINAL VEIN OCCLUSION AT THE GLAUCOMA CLINIC OF HIROSHIMA-UNIVERSITY

We prospectively surveyed the incidence of retinal vein occlusion (RVO ) at the glaucoma clinic of Hiroshima University between 1986 and 1991 . Among 433 glaucoma patients, 18 (4.2%) subsequently presented with R VO, 9 had central retinal vein occlusion (CRVO) and 9 exhibited branch retinal vein occlusion (BRVO). Seven of 87 (8.1%) patients with prima ry angle closure glaucoma exhibited RVO, showing the highest incidence among glaucoma types. The incidence of RVO detected by the general ou tpatient clinic was 0.59% during the same period. The BRVO/CRVO ratio in the glaucoma clinic was 1.0, while it was 4.3 in the general outpat ient clinic. Glaucoma is an important risk factor for the development of RVO, especially CRVO.
