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...
متن کاملAdvanced Analysis of PRVEP in Anisometropic Amblyopia
Introduction: to identify the pattern-reversal visual evoked potential (PRVEP) waveform descriptor by evaluating discrete wavelet transform (DWT) in order to optimize stimulus in the diagnosis of anisometropia amblyopia. Materials and Methods: The PRVEP testing was performedfor 31 normal individuals and 35 patients with amblyopia. The stimuli were consisted of spatial frequencies of 1, 2, and 4...
متن کاملContour integration in anisometropic amblyopia
Contour integration was measured in a group of anisometropic amblyopes to test the idea recently put forward that positional uncertainty sets a fundamental limit to contour integration in amblyopia. Anisometropic amblyopia, unlike strabismic amblyopia, has little or no positional uncertainty once the initial filtering loss has been taken into account. Therefore, according to the explanation put...
متن کاملContrast sensitivity in anisometropic amblyopia.
Contrast sensitivity functions were measured for sinusoidal gratings from a sample of 10 anisometropic amblyopes. A high spatial frequency deficit was found from tests of the amblyopic eyes of all subjects. This defect decreased with spatial frequency and was correlated with the magnitude of anisometropia. Controls were instituted to rule out psychophysical method and residual defocus as possib...
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...
