点眼麻酔下の小切開白内障手術後早期の眼圧経過

A postoperative intraocular pressure following small-incision cataract surgery under instillation anesthesia

（展示31）　点眼麻酔下の小切開白内障手術予定者で，緑内障などの術後眼圧上昇の危険因子がない61例62眼で，術前後の眼圧を測定した。眼圧降下のための治療は行わなかった。術前の眼圧は，14.9±2.2mmHg（平均±標準偏差）であり，術後3,6,10,24時間後，2日後，3日後の眼圧は，それぞれ18.2±3.6,17.9±3.4,17.1±3.2,15.0±2.8,13.7±2.4,13.1±2.1mmHgであり，経過中30mmHgを越えた症例はなかった。術後早期の眼圧上昇は，年齢，眼軸長，超音波操作時間，手術所要時間，切開方法のいずれとも相関しなかった。

We measured the intraocular pressure (I013) in a consecutive series of 62 eyes before and after small-incision cataract surgery under instillation anesthesia. Eyes with glaucoma were excluded from the study. No case was given antiglaucomatous treatment. The TOP averaged 14.9 ± 2.2 mmHg before surgery. It averaged 18.2 ± 3.6, 17.9±3.4, 17.1 ±3.2, 15.0 ± 2.8, 13.7 ± 2.4, 13.1 ± 2.1 mmHg respectively at 3, 6, 10, 24 hours, 2 days and 3 days after surgery. No eye showed elevation of IOP over 30 mmHg. The rise of IOP during the immediate postoperative period was not correlated either with age, axial length, duration of ultrasound application, duration of surgery or method of incision.
