自己閉鎖創を用いた白内障・緑内障同時手術の成績

Results of simultaneous self-sealing surgery for cataract and glaucoma

　白内障，開放隅角緑内障合併症例10例13眼に，マイトマイシンC併用線維柱帯切除術に線維柱帯切開術を併用し，自己閉鎖創白内障手術を行った症例の短期手術成績を検討した。経過観察期間は6〜15か月（平均8.7か月）であった。術後6か月での視力は，0.5以上が11眼（85％），このうち3眼（27％）は術後3日以内，6眼（55％）は術後6日以内の早期に達した。術性乱視は軽微で，術後2〜3か月以降は比較的安定した。術後6か月では，全例が無治療で平均眼圧は9,92mmHg，濾過胞は12眼（92％）にみられた。本術式は，自己閉鎖創白内障手術の利点と線維柱帯切除術の効果が期待され，安全かつ有用な手術法と思われた。

We treated 13 eyes with cataract and open-angle glaucoma by combined self-sealing phacoemul-sification and trabeculectomy with trabeculotomy. The follow-up period ranged from 6 to 15 months, median 8.7 months. Corrected visual acuity of 0.5 or better was achieved in 11 eyes, 85%, at 6 months after surgery. Surgically induced astigmatism was minimum and stabilized within 2 to 3 months postoperatively. Intraocular pressure of 21 mmHg or less without medication was attained in all the eyes and averaged 9.9 mmHg. Visible bleb was present at 6 months in 12 eyes, 92%. Above results show the safety and efficacy of our combined surgical procedure for cataract and glaucoma.
