要約 目的:川崎医科大学附属病院眼科での緑内障に対するリパスジルの使用状況とその効果の報告。
対象と方法:2016年7月までの18か月間にリパスジル点眼液を処方された54例82眼を対象とした。男性43眼,女性39眼で,年齢は27〜91歳,平均64.6±15.2歳であった。病型は原発開放隅角緑内障(POAG)29眼,正常眼圧緑内障(NTG)18眼,落屑緑内障10眼,ステロイド緑内障8眼,その他17眼であった。投与開始前の眼圧は9〜31mmHg,平均17.5±0.5mmHg,点眼スコアは3.5±1.0であった。10%以上の眼圧下降があった場合を有効と判定し,投与3か月後の効果の有無につき,患者背景を検討した。
結果:投与開始から3か月後の時点で67眼が継続投与中であり,38眼が有効,29眼が無効であった。有効群は無効群よりも有意に年齢が低かった(p=0.013)。病型別では,ステロイド緑内障とPOAGに有効例が多く,落屑緑内障に少なかった。6か月間投与を続けた56眼の平均眼圧は,投与前16.6mmHg,1か月後15.0mmHg,3か月後14.5mmHg,6か月後14.2mmHgと有意に下降した。副作用で12眼が治療を中断し,うち10眼が6か月後であった。
結論:多剤併用緑内障患者でもリパスジル点眼で眼圧が下降した。投与開始から6か月の間段階的に眼圧が下降した。副作用は6か月間の投与で多く生じた。
Abstract Purpose:To report the status and effect of ripasudil ophthalmic solution for glaucoma.
Cases and Method:This retrospective study was made on 82 eyes of 54 cases who were treated by ripasudil ophthalmic solution during 18 months through July 2016. The series comprised 43 male and 39 female eyes. The age ranged from 27 to 91 years, average 64.6±15.2 years. There were 29 eyes with primary open-angle glaucoma(POAG), 18 eyes with normal-tension glaucoma, 8 eyes with steroid glaucoma, and 7 eyes with other types of glaucoma. Intraocular pressure(IOP)before treatment with ripasudil ranged from 9 to 31 mmHg, average 17.5±0.5 mmHg. Medication score averaged 3.5±1.0. Treatment was evaluated as effective when IOP decreased by 10% or more at 3 months of treatment.
Results:A total of 67 eyes continued treatment with ripasudil 3 months after start, of which 38 were evaluated as effective and 29 eyes were ineffective. Lower age was significantly associated with effective response(p=0.013). Treatment was more effective for POAG and steroid glaucoma than capsular glaucoma. IOP averaged 16.6 mmHg before treatment, 15.0 mmlig at 1 month, 14.5 mmHg at 3 months, and 14.2 mmHg at 6 months. Treatment was discontinued in 12 eyes, of which 10 discontinued after 6 months of treatment.
Conclusion:IOP decreased even in eyes receiving multiple medications. IOP showed step-wise decrease during 6 months of treatment with ripasudil. Young patients showed more response. Side effects tended to develop after 6 months of treatment.
