老視に対する調節訓練（第4報）—長期継続例

Accommodation training for presbyopia (Report 4) :Review of long-term training

（展示66）　1年以上調節訓練を継続した40歳代の老視5例9眼で，調節訓練の長期効果を検討した。最終検査時の調節力は，全例で開始前のそれを上回つていた。また自覚症状も全例で改善していた。今回の結果から，調節力を良好に維持するためには1日5〜20回の調節訓練が必要と思われた。

We performed accommodation training for presbyopia in five persons for one year or longer. All the patients were in the fifth decade of life. All the cases showed increased amplitudes of accommodation at the final examination than before start of training. Subjective symptoms of presbyopia had also improved in all the cases. It appeared that daily accommodation training repeated 5 to 20 times is necessary to maintain improved state of accommodation for longer periods.
