要約 目的:複数の薬物で加療中の原発開放隅角緑内障に,ブリモニジン点眼を追加した短期経過の報告。対象と方法:眼圧コントロールが不良な原発開放隅角緑内障40例53眼を対象とした。男性31眼,女性21眼で,平均年齢は67.9±12.7歳,平均眼圧は18.3±3.1mmHgであった。全例がプロスタグランジン関連薬,β遮断薬,炭酸脱水酵素阻害薬などを点眼中であった。0.1%ブリモニジン酒石酸塩の点眼を1日2回これに追加し,6か月後までの経過を追った。結果:追加点眼開始から1か月後,3か月後,6か月後の眼圧の平均下降率は,それぞれ8.3%,6.9%,8.2%であった。20%以上の眼圧降下は,それぞれ25%,32%,23%にあった。12眼では効果が不十分なため,1眼ではふらつきのために点眼を中止した。結論:複数の薬物で加療中の原発開放隅角緑内障に対し,ブリモニジン点眼の追加により,約20%の症例で眼圧が下降した。
Abstract. Purpose:To present a report on short-term hypotensive effect of brimodinine added to multiple medications for primary open-angle glaucoma(POAG). Cases and Method:This retrospective study was made on 53 eyes in 40 cases of POAG that failed to respond to multiple medications. The series comprised 31 male and 21 female eyes. The age averaged 67.9±12.7 years. Intraocular pressure(IOP)averaged 18.3±3.1 mmHg. All the cases had been receiving topical treatment with prostaglandins, beta-blocker and carboxyl anhydrase inhibitor. Additional instillation of 0.1% brimonidine was started twice daily. Cases were followed up for 6 months. Results:Averaged IOP decreased by 8.3%, 6.9% and 8.2% after 1, 3 and 6 months of treatment. IOP decreased by 20% or over in 25%, 32% and 23% of eyes respectively. Instillation of brimonidine was discontinued in 12 eyes due to insufficient hypotensive effect and in one eye due to dizziness. Conclusion:IOP decreased in 20% of eyes after instillation of brimonidine added to multiple mediations for POAG.
