Macular puckerに対する硝子体手術の経験

Outcome of vitreous surgery for macular pucker

　Macular puckerに対する硝子体手術の6症例7眼を経験した。Macular puckerの原因は，特発性のもの3例3眼，網膜剥離手術に続発したもの2例2眼，ターソン症候群に続発したもの1例2眼であった。手術によって5眼に視力が改善した。術後の視力回復経過を詳細に検討したところ，術後1か月から2か月の間に急激な視力上昇がみられ，3か月以降では大きな変動がなかった。術後視力は，網膜上膜の形態学的変化から予測できず，螢光眼底撮影による網膜の器質的変化の検索が重要であった。

We treated 7 eyes of macular pucker with closed vitrectomy.Macular pucker was idiopathic in 3 eyes, secondary to retinal detachment surgery in 2 eyes and consequent to Terson's syndrome in 2 eyes. During the process of membrane peeling, retinal hemorrhage developed in 3 eyes and retinal hole in one. These complications did not affect thefinal vision. Nuclear cataract developed in one eye, necessitating later cataractsurgery.

Out of the 7 eyes in the series, the visual acuity improved in 5, remained unchanged in 1 and dete-riorated in 1. Improvement in visual acuity was rapid during the initial 3 months after surgery.Thevisual acuity became stationary from the fourth month on. The postoperative visual acuity was more dependent on the cystoid macular edema rather than the thickness of epiretinal membrane.
