老視に対する調節訓練—第3報老視の改善

Accommodation training for presbyopia. Report 3. Improvement of presbyopia

　過去30か月の間に，2か月以上にわたり調節訓練を行った40代の老視20例の調節力，屈折値および自覚症状の変化を検討した。屈折値は変化しなかったが，調節力は2か月間の訓練後に，対照群と比較して有意に増加していた。また，老視の自覚症状は20例中15例で改善した。今回の結果から，この方法は初期の老視の患者に対して，最初の眼鏡を作る前にまず試してみる価値のあるものと思われた。

We performed accommodation training on 20 presbyopes for two months or longer. The subjects were aged 42 to 49 years. We evaluated their state of refraction, amplitude of accommodation and symptoms of presbyopia before and two months after training. After training, the state of refraction remained unchanged and the average amplitude of accommodation increased significantly when compared with controls. Subjective symptoms of presbyopia improved in 15 cases. These findings show the efficacy of this training in early presbyopes before they start using reading glasses.
