高齢患者のアイフレイル調査

Survey of eye-frail in elderly patients

要約　目的：アイフレイルとは加齢に伴って視機能が低下した状態を指す。今回，高齢者のアイフレイル状況を検討した。

対象と方法：井上眼科病院を受診した60歳以上の初診患者のうち，アイフレイル自己チェック10項目（質問①〜⑩）を実施した2,140例を対象とした。チェック数，各項目について男女別，年齢別（60歳台，70歳台，80歳以上）に比較した。

結果：チェック数は，男性（826例）3.4±2.2個は女性（1,314例）3.8±2.2個より有意に少なかった。60歳台（940例）3.4±2.1個，70歳台（841例）3.8±2.2個，80歳以上（359例）4.2±2.4個で，年齢とともに有意に増加した。60歳台では，①疲れやすい63.6％，⑤眼鏡をかけてもよく見えない51.7％，③新聞や本を長時間見ない48.7％，70歳台では，①疲れやすい62.2％，⑤眼鏡をかけてもよく見えない58.1％，③新聞や本を長時間見ない57.3％，80歳以上では，①疲れやすい64.3％，⑤眼鏡をかけてもよく見えない64.3％，③新聞や本を長時間見ない62.4％の順でチェックした人が多かった。

結論：アイフレイル症状は女性の高齢者に多く，年齢とともに増加していた。高齢者でのチェック項目は，年齢にかかわらずほぼ同等であった。

Abstract　Purpose：Eye-frail is a condition in which visual function declines with age. In this study, we investigated the status of eye-frail in the elderly.

Methods：A total of 2,140 patients, aged 60 years or older, who initially visited Inouye Eye Hospital and completed the 10 items of the eye-frail self-check were analyzed. The mean frequency of each item were compared by gender and age（60s, 70s, and 80s-90s）.

Results：The mean number of checks for men（n＝826）was 3.4±2.2, which was significantly lower than that of women（3.8±2.2, n＝1,314）. The frequency of checks significantly increased with age：3.4±2.1 between 60 and 69 years（n＝940）；3.8±2.2 between 70 and 79 years（n＝841）；and 4.2±2.4 between 80 and 99 years（n＝359）. Individuals age between 60 and 69 years most frequently reported following order：‘get tired easily’（63.6％）, ‘could not see well even with glasses’（51.7％）, and ‘did not read newspapers or books for a long time’（48.7％）. In the 70s, the checks were more frequent in the following order：‘get tired easily’（62.2％）, ‘could not see well even with glasses’（58.1％）, and ‘did not read newspapers or books for a long time’（57.3％）. Individuals aged 80 years and older most frequently reported following order：‘get tired easily’（64.3％）, ‘could not see well even with glasses’（64.3％）, and ‘do not read newspapers or books for a long time’（62.4％）.

Conclusion：Eye-frail checks were more frequent in women, among the elderly, and increased with age. In the elderly, the checked items were similar regardless of age.
