Abstract

AC/A ratio of alternating fixation metbod(AF) using Major Amblyoscope was compared with that of simultaneous fixation method(SF). Under SF, AC/A ratio was greater than that of AF and standard deviation of both method was not significantly different. This indicates tbat AC/A ratio of SF was not accurate, because fusional convergence was invariably participated. Therefore, when we measure the AC/A ratio by tbe gradient method using the Major Amblyoscope, AF was desirable.
