In order to examine noncomitant squint,various methods have been used recently ; they are, for example, the Hess chart, testing the fixation field, photographing the compensatory postures and ocular movements etc. A fairly wide space is necessary to do these examina-tions. But in our daily practice, the small and convenient apparatus is required to perform complex examinations in a narrow room. Just for this purpose,have reported an apparatus of my original design previously(Teishin Igaku Journal 1952)which enabled us to test both diplopia and after-image in siti.This report presents a more refined and improved appara-tus which I have succeeded to design lately.
