Perceptual learning improves contrast sensitivity and visual acuity in adults with anisometropic amblyopia
To evaluate the effects of perceptual learning on contrast-sensitivity function and visual acuity in adult observers with amblyopia, 23 anisometropic amblyopes with a mean age of 19.3 years were recruited and divided into three groups. Subjects in Group I were trained in grating detection in the amblyopic eye near pre-training cut-off spatial frequency. Group II received a training regimen of r...
متن کاملPerceptual learning improves contrast sensitivity, visual acuity, and foveal crowding in amblyopia.
BACKGROUND Amblyopic observers present abnormal spatial interactions between a low-contrast sinusoidal target and high-contrast collinear flankers. It has been demonstrated that perceptual learning (PL) can modulate these low-level lateral interactions, resulting in improved visual acuity and contrast sensitivity. OBJECTIVE We measured the extent and duration of generalization effects to vari...

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 کاملEfficacy of perceptual vision therapy in enhancing visual acuity and contrast sensitivity function in adult hypermetropic anisometropic amblyopia
BACKGROUND The purpose of this study was to evaluate the efficacy of neural vision therapy, also termed perceptual vision therapy, in enhancing best corrected visual acuity (BCVA) and contrast sensitivity function in amblyopic patients. METHODS This prospective study enrolled 99 subjects previously diagnosed with unilateral hypermetropic amblyopia aged 9-50 years. The subjects were divided in...
