要約 目的:緑内障患者の実態を調査し,さらに2016年に行った前回調査との比較を行うこと。
対象と方法:本調査の趣旨に賛同した78施設に2020年3月8〜14日に外来受診した緑内障,高眼圧症患者5,303例5,303眼を対象とした。緑内障病型,手術既往歴,使用薬剤を調査した。
結果:病型は正常眼圧緑内障51.1%,原発開放隅角緑内障30.9%,続発緑内障8.2%などであった。使用薬剤数は平均1.8±1.3剤で,無投薬10.2%,1剤41.5%,2剤23.0%,3剤14.2%などであった。1剤使用例はプロスタグランジン(PG)関連薬66.7%,β(αβ)遮断薬22.1%などであった。2剤使用例はPG/β配合剤42.8%,PG関連薬とβ(αβ)遮断薬併用13.3%,炭酸脱水酵素阻害薬/β遮断薬配合剤12.0%などであった。
結論:前回調査と比較し,1剤使用例はPG関連薬が有意に減少し,2剤使用例はPG/β配合剤が有意に増加し,PG関連薬とβ遮断薬併用が有意に減少した。
Abstract Purpose:We investigated the current status of glaucoma patients and compared it to a previous survey in 2016.
Patients & Methods:A total of 5,303 patients(5,303 eyes)with glaucoma or ocular hypertension who had visited from March 8 to 14 in 2020 at 78 institutions with the approval of the survey were included in this study. The type of glaucoma, history of surgery, and number of medications were investigated.
Results:The diagnosis was normal-tension glaucoma in 51.1% of subjects, primary open-angle glaucoma in 30.9% of subjects, secondary glaucoma in 8.2% of subjects, and others. The mean number of medications was 1.8±1.3:no current medications in 10.2% of subjects, a single medication in 41.5% of subjects, two medications in 23.0% of subjects, three medications in 14.2% of subjects, and others. The breakdown of patients receiving a single medication was prostaglandin(PG)analogs in 66.7% of patients, β(αβ)-blockers in 22.1% of patients, and others. The breakdown of patients receiving two medications was PG/β fixed combination in 42.8% of patients, PG analogs and β(αβ)-blockers in 13.3% of patients, carbonic anhydrase inhibitor/β-blocker fixed combination in 12.0% of patients and others.
Conclusion:Compared to the previous survey, the number of patients taking PG analogs significantly decreased among those receiving a single medication. In contrast, the number of patients taking the PG/β fixed combination significantly increased and the number of patients taking PG analogs and β-blockers significantly decreased among those receiving two medications.
