Dichoptic training improves contrast sensitivity in adults with amblyopia
Dichoptic training is designed to promote binocular vision in patients with amblyopia. Initial studies have found that the training effects transfer to both binocular (stereopsis) and monocular (recognition acuity) visual functions. The aim of this study was to assess whether dichoptic training effects also transfer to contrast sensitivity (CS) in adults with amblyopia. We analyzed CS data from...
متن کاملPerceptual 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 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 کاملContrast sensitivity following amblyopia treatment in children.
P rior studies have found a reduction in contrast sensitivity in eyes with amblyopia using sinusoidal gratings, whereas minimal loss has been reported with Pelli-Robson charts. Most studies have evaluated contrast sensitivity at the time of diagnosis of amblyopia or after short-term treatment. A follow-up study of an earlier randomized trial provided us the opportunity to evaluate contrast sens...
متن کاملAmblyopia treatment of adults with dichoptic training using the virtual reality oculus rift head mounted display: preliminary results
BACKGROUND The gold standard treatments in amblyopia are penalizing therapies, such as patching or blurring vision with atropine that are aimed at forcing the use of the amblyopic eye. However, in the last years, new therapies are being developed and validated, such as dichoptic visual training, aimed at stimulating the amblyopic eye and eliminating the interocular supression. PURPOSE To eval...
