黄斑浮腫のある網膜静脈分枝閉塞症の発症から6か月以内の新鮮例への治療方針を5年前に設定し,これによる65眼での成績を評価した。軽度黄斑浮腫15眼は保存的に治療し,中等度黄斑浮腫22眼には光凝固を行い,高度黄斑浮腫28眼中24眼には硝子体手術を行った。最終視力は61眼全例で0.3以上,54眼(89%)で0.5以上,47眼(77%)で0.7以上であった。高度黄斑浮腫24眼中14眼(58%)で0.7以上の視力が得られた。高度黄斑浮腫のある網膜静脈分枝閉塞症新鮮例に対して硝子体手術を行うことで,高率の視力改善が期待できることを示す所見である。
We reviewed 65 eyes of early-stage branch retinal vein occlusion treated according to our guideline estblished 5 years ago. Fifteen eyes with mild macular edema received conservative treatments, 22 eyes with medium-grade macularedema received photocoagulation, and 24 out of 28 eyes with severe macular edema received vitrectomty. The final visualacuity in 61 eyes was 0.3 or better in 61 eyes (100%), 0.5 or better in 54 eyes (89%), and 0.7 or better in 47 eyes (77%) . Visual acuity of 0.7 or better was attained in 14 of 24 eyes following vitrectomy for severe macular edema. The findingsshow that improvement of visual acuity can be expected at a high rate even in eyes with severe macular edema whentreated by early vitrectomy.
