LOCAL ADAPTATION IN FUNCTIONAL AMBLYOPIA

Three experiments dealing with comparisons between amblyopic and normal eyes are described. The first demonstrated that the fixation pattern of amblyopic eyes differs from that of normal eyes. The timing of the different subjective phenomena noted in these eyes can be correlated with the timing of fixation events. In the second experiment it was not possible to demonstrate that as exposure time of acuity targets is reduced when comparing amblyopic with normal eyes, the respective visual acuities of the two eyes tend to become similar. In the third experiment it was demonstrated that local adaptation proceeds faster in the central and para-central region of the amblyopic eye than in the normal fellow eye. © 1968.
