緑内障患者の点眼状況

Current status of topical medication by glaucoma patients

目的：緑内障患者の点眼状況の調査とこれに関与する因子の検討。方法：大学病院に通院している開放隅角緑内障患者から無作為に選んだ168名を面接法で調査した。男性42％，女性58％で，年齢は21～84歳（平均61歳）であった。結果：被調査者の84％が「1か月間点眼を忘れたことがない」，8％が「1か月間に1～3回忘れる」と回答した。点眼状況は視野障害と関連があり，ハンフリー視野30-2のMDと有意に相関した（p＜0.05）。昼間の点眼状況は，朝と夕方から夜間のそれより有意に不良であった（p＜0.05）。結論：緑内障が重症化するにつれ病識が向上し，点眼状況が良好になる。病識を高めることがコンプライアンスをよくすると推定される。

Purpose：To evaluate the state of use of eyedrops by patients of open-angle glaucoma,and to assess related factors. Method：A total of 168 glaucoma patients were interviewed who were randomly chosen out of those attending Saga University Hospital. The series comprised 74 males（42％）and 94 females（58％）. Their ages ranged from 21 to 84 years,average 61 years. Results：Eyedrops were being instilled in full accordance to prescriptions by 84％ of patients. Instillation of eyedrops was missed one to three times a month by 8％ of patients. Eyedrops were more correctly used by patients with more advanced visual field defect. A significant correlation was present between complicance and mean deviation（MD）by program 30-2 of Humphrey visual field analysis. Compliance was worse in instillation in daytime than that in the morning or evening（p＜0.05）. Conclusion：Eyedrops are more correctly used by glaucoma patients with more advanced visual field defect. Improved awareness of glaucoma may result in better complicance.
