Centrally fixed flicker thresholds in amblyopia.
Theories as to the etiology of amblyopia (also called amblyopia ex anopsia, strabis mus amblyopia, and amblyopia without ophthalmoscopic signs) may roughly be divided into two groups depending upon whether the primary defect is postulated in the cere bral cortex or in the retina. Wald and Burian who are among the most lucid ad vocates of the former position described measurements on five cas...
متن کاملFlicker fusion frequency in amblyopia ex anopsia.
Amblyopia ex anopsia is characterized by a defect in visual acuity of one eye, beginning in infancy, often with strabismus. The amblyopia disappears upon occlusion of the dominant eye in children, but not readily in adults. Peripheral acuity and sensation remain normal in field and threshold studies. It is believed that the origin of the amblyopia is in the macular projection of the visual cort...

متن کاملPsychophysical investigations of the temporal modulation sensitivity function in amblyopia: uniform field flicker.
The temporal modulation sensitivity function was studied in eight strabismic and/or anisometropic amblyopes and in two subjects with amblyopia resulting from monocular stimulus deprivation (cataract and ptosis). Half of the strabismic/anisometropic amblyopes showed a reduction in the sensitivity of the amblyopic eye. These differences were more marked at low and middle temporal frequencies. Two...
