    peer reviewedThe dark adaptation of the cones of the amblyopic eye is somewhat reduced. This decrease is less important than the reduction of the visual acuity. The flicker fusion frequency of the central and paracentral areas of the visual field of the amblyopic eye is not reduced. On the contrary, statistical calculation shows an inconspicuous increase. The visual acuity of the amblyopic eye is all the more reduced as the test is more searching. This lack of harmony between the angular visual acuity and the morphoscopic visual acuity is pre-existent to any treatment. Though in different degrees, it is found in amblyopia with central fixation and in amblyopia with eccentric fixation. On the other hand it is not revealed in organic lesions of the eye or of the optic tracts. Any visual image that is perceived by an amblyopic eye is the source of memorization phenomena that are identical to any image discerned by the healthy brother eye. © 1962 Uitgeverij Dr W. Junk
