緒言

　石原氏国際色盲検査表の第1表，第38表以外は判読出来ず，羞明，弱視，眼球振盪を見ない先天性全色弱の一例を経験し，種々の検査を試みたので報告したい。

Reports of a male aged 19 who was diagnosed to have congenital total colour-weakness by examination using many kinds of pseudoisochromatic plates and type II of the anoma-loscope. In investigation using type II of the anomaloscope, it was matched like deutera-nopia, further it matched at the side of a short wave length, that should not match in the case of deuteranopia. From this result it looks as if trianopia exists, and the conclu-sion of this case was that deuteranopia with tritanopia existed at the same time.
