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 کاملAn Assessment of the Contrast Sensitivity in Patients with Ametropic and Anisometropic Amblyopia in Achieving the Corrected Visual Acuity of 1.0
Both visual acuity (VA) and contrast sensitivity (CS) are important parameters for measuring visual function. In this research, we investigated the CS of patients with ametropic or anisometropic amblyopia, whose corrected visual acuity (CVA) recovered to 1.0. Fifty-five cases with amblyopia and 22 control cases with a normal visual acuity of 1.0 were enrolled. The CS of the patients whose ametr...
متن کاملEvaluation of contrast visual acuity in patients with retinitis pigmentosa
BACKGROUND The purpose of this study was to determine visual acuity at different contrast levels under photopic and mesopic conditions in patients with retinitis pigmentosa. METHODS Sixty eyes of 31 normal controls, 92 eyes of 52 patients with retinitis pigmentosa without other ocular disorders (RP-1 group), and 20 eyes of 14 patients with retinitis pigmentosa with cataracts and without other...

purpose : to investigate the discriminative ability of contrast sensitivity (cs), color vision and best corrected visual acuity (bcva) in detecting functional losses in diabetic participants with and without retinopathy methods : in this cross sectional study we examined 105 patients in khatam-al-anbia eye hospital of mashhad university of medical sciences including 70 diabetic patients (35 wit...
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...
