慢性閉塞隅角緑内障に対する水晶体摘出の影響

Course of chronic primary angle closure glaucoma following cataract surgery

（18-P3-8）　超音波吸引術と眼内レンズ挿入術を行った55症例60眼を検討した。全例に慢性閉塞隅角緑内障があった。年齢は平均67.4±4.9歳であつた。術後の眼圧には，術前の眼圧と前房深度との影響が大きかった。術前にPAS indexが75％以下または前房深度2.00mmの27眼中26眼で，全身的薬物投与なしで20mmHg以下の眼圧コントロールが得られた。上記の条件を満たす慢性閉塞隅角緑内障の白内障に対しては，超音波吸引術と眼内レンズ挿入術が第一選択になると結論される。

We reviewed 60 eyes in 55 patients which underwent cataract surgery by phacoemulsification and intraocular lens implantation. All the eyes had also chronic primary angle closure glaucoma. The ages averaged 67.4 ± 4.9 years. The postoperative intraocular pressure (IOP) was influenced by preoperative TOP and anterior chamber depth. Success rate in TOP control was correlated with preoperative TOP, anterior chamber depth and PAS index. Postoperative IOP control below 20 mmHg without systemic medication was achieved in 26 out of 27 eyes which showed 75% or less in PAS index or 2.00 mm in anterior chamber depth before surgery. Cataract surgery by phacoemulsification and intraocular lens implantation is indicated to eyes with chronic primary angle closure glaucoma only when above features are satisfied.
