(P−1-99) 網膜中心静脈閉塞症に黄斑浮腫が生じ,視力が0.1以下の11眼に対して硝子体手術を行った。黄斑浮腫は7眼で6か月以内に消失した。視力は6眼で改善した。網膜中心静脈閉塞症が発症してから6か月以内に手術を行った7眼では5眼で視力が改善し,7か月以降の4眼では1眼で視力が改善した。この差は有意であった(p<0.05)。視力低下が強い黄斑浮腫を伴う網膜中心静脈閉塞症では,早期の硝子体手術によって浮腫の改善と視力の向上が得られることを示す症例群である。
We performed vitreous surgery on 11 eyes in which the visual acuity was reduced to 0.1 or less due to central retinal vein occlusion with macular edema. Macular edema resolved in 7 eyes within 6 months of surgery. Visual acuity improved in 6 eyes. Visual acuity improved in 5 out of 7 eyes when surgery was performed within 6 months after onset. It improved in 1 out of 4 eyes when surgery was performed later. The difference was significant (p < 0.05). The findings show that early vitreous surgery may induce resolution of macular edema and improved visual acuity in eyes with markedly reduced visual acuity due to central retinal vein occlusion with macular edema.
