硝子体，白内障，眼内レンズ同時手術後，最高視力に達するまでの期間

Interval between maximum visual acuity and simultaneous surgery with vitrectomy and cataract surgery

　硝子体手術と眼内レンズ挿入術を同時に行った411眼につき，術後の最高視力が得られるまでの期間を検討した。全例では平均8.3か月であり，黄斑上膜85眼で8.2か月，分層黄斑円孔30眼で7.3か月，可糖尿病黄斑浮腫47眼で6.0か月，その他の黄斑浮腫36眼で7.3か月，黄斑円孔126眼で10.1か月，増殖糖尿病網膜症54眼で8.4か月，網膜下病変17眼で5.8か月，硝子体出血16眼で7.5か月であった。有意差が，黄斑円孔と糖尿病黄斑浮腫間（p＝0.0026），糖尿病黄斑浮腫と増殖糖尿病網膜症間（p＝0.05）にあった。年齢とは相関しなかった。最高視力の値と相関する因子は，最高視力が得られるまでの期間（R²＝0.02）と年齢（R²＝0.074）であった。

We evaluated 411 eyes regarding the interval between maximum visual acuity and simultaneous triple surgery with vitrectomy, phacoemulsification-aspiration and intraocular lens implantation. The interval averaged 8.3 months in the whole group. It was 8.2 months in epiretinal membrane 85 eyes, 7. 3 months in lamellar macular hole 30 eyes, 6.0 months in diabetic macular edema 47 eyes, 7.3 months in nondiabetic macular edema 36 eyes, 10.1 months in macular hole 126 eyes, 8.4 months in proliferative diabetic retinopathy 54 eyes, 5.8 months in subretinal lesions 17 eyes and 7.5 months in vitreous hemorrhage 16 eyes. It was not correlated with age. Significant differences were present between macular hole and diabetic macular edema (p = 0.0026), and between diabetic macular edema and proliferative diabetic retinopathy (p = 0.05). The value of maximum visual acuity was significantly correlated with the duration after surgery and age.
