緑内障・白内障同時手術の成績

Outcome of simultaneous surgery for glaucoma and cataract

　過去23か月間に緑内障と白内障同時手術を行った26眼を検索した。術式は，マイトマイシンC併用線維柱帯切除術，水晶体超音波乳化吸引術，折りたたみ眼内レンズ挿入術である。同時期にマイトマイシンC併用線維柱帯切除術を単独で行った41眼を対照とした。Kaplan-Meier法で解析した術後6か月以上での眼圧調整率は，同時手術群では83.3％，単独手術群では78.0％であり，両群間に差はなかった（p＝O．698）。同時手術群では77％で2段階以上に視力が改善した。今回の手技による緑内障と白内障同時手術は有用であると結論される。

We reviewed 26 eyes which underwent simultaneous surgery for glaucoma and cataract during a 23-month period. The surgical modality comprised trabeculectomy with mitomycin C, phacoemulsification-aspiration and intraocular lens implantation. Another series of 41 eyes treated by trabeculectomy with mitomycin C alone served as control. All cases were followed up for 6 months or longer after surgery. Life-table analysis after Kaplan-Meier showed the probability of control of intraocular pressure to be 83.3% in the combined surgery group and 78.0% in the trabeculectomy group. There was no difference between the two groups (p=0.698) . The corrected visual acuity improved in 77% of eyes in the combined surgery group. The findings show the effective-ness of combined surgery for glaucoma and cataract.
