Outline of Final Research Achievements

The purpose of this study was to develop a new amblyopia treatment device that can be implemented inexpensively and easily, and to examine its usefulness and effectiveness. By attaching one polarizing film to a TV or a book, and another polarizing film with its axis rotated by 90 degrees to the healthy eye of a pair of glasses, we were able to develop a new device that can present optotypes only to the amblyopic eye under binocular opening. This device solves the problem of price and ease of use as a binocular open type amblyopia treatment device, which has been a problem until now. We conducted amblyopia treatment for patients with anisometropic amblyopia using this device, and obtained good amblyopia treatment results.

Academic Significance and Societal Importance of the Research Achievements

これまで開発されたきた両眼開放下の弱視訓練装置は特殊な電子機器であるため、患者一人ひとりが自宅で使用することが極めて困難であった。そこで本研究において偏光フィルムを用いた新たな弱視訓練装置を開発することにより、手軽かつ安価に両眼開放下の弱視訓練を実施することができるようになった。これにより、弱視患者の弱視訓練に対する負担を軽減することに繋がると考えられる。
