Abstract

Forty three eyes with vitreous hemorrhage caused by branch retinal vein occlusion had been underwent pars plana vitrectomy and followed-up over 6 months. The eyes were classified into 4 groups according to intraoperative fundus findings-group 1; vitreous hemorrhage only, group 2; vitreous hemorrhage with fibrovascular proliferation, group 3; vitreous hemorrhage with traction retinal detachments, group 4; vitreous hemorrhage with rhegmatogenous retinal detachments. Analysis was focused on the clinical characteristics and postoperative outcome in each group. The durations of vitreous hemorrhage were longer significantly in group 2 and group 3. The vision improved postoperatively in 35 of 43 eyes(81.3%). The percentage of postoperative visual improvements was 100%(18 of 18 eyes) in group 1, 85.7%(12 of 14 eyes) in group 2, 66.6%(4 of 6 eyes) in group 3, and 20$(1 of 5 eyes) in group 4. The preoperative ultrasono-graphic findings of retinal status were accorded with intraoperative retinal findings in 74.4% of eyes.
