Relating binocular and monocular vision in strabismic and anisometropic amblyopia.
OBJECTIVES To examine deficits in monocular and binocular vision in adults with amblyopia and to test the following 2 hypotheses: (1) Regardless of clinical subtype, the degree of impairment in binocular integration predicts the pattern of monocular acuity deficits. (2) Subjects who lack binocular integration exhibit the most severe interocular suppression. METHODS Seven subjects with anisome...

Results: As expected, both groups showed deficits in monocular acuity, with subjects with strabismus showing greater deficits in Vernier acuity. Both amblyopic groups were then characterized according to the degree of residual stereoacuity and binocular motion integration ability, and 67% of subjects with strabismus compared with 29% of subjects with anisometropia were classified as having “non...
متن کاملBinocular combination in anisometropic amblyopia.
Using a suprathreshold binocular summation paradigm developed by J. Ding and G. Sperling (2006, 2007) for normal observers, we investigated suprathreshold cyclopean perception in anisometropic amblyopia. In this paradigm, two suprathreshold sinewave gratings of the same spatial frequency but different spatial phases are presented to the left and right eyes of the observer. The perceived phase o...
متن کاملSuprathreshold spatial frequency detection and binocular interaction in strabismic and anisometropic amblyopia.
We have investigated suprathreshold contrast sensitivity and binocular interactions in strabismic and anisometropic amblyopes using a reaction time paradigm. For every spatial frequency, reaction time increased as the grating contrast decreased. At all spatial frequencies and contrast values the reaction times using the amblyopic eye were prolonged compared to the nonamblyopic eye, but most mar...
متن کاملSpatio-temporal interactions in anisometropic and strabismic amblyopia.
Contrast sensitivity functions for sinusoidal gratings of different spatial frequencies and stimulus durations have been determined for both eyes of amblyopic subjects. For both long and short stimulus durations, the entire contrast sensitivity function of the amblyopic eyes is lower than that of the nonamblyopic eyes. When the gratings were flickered at 10 Hz, the sensitivity for pattern and f...
