Evaluation of Amblyopia Protocols Using a Dichoptic Gabor Videogame Program

Visionary exercises are computer gammified activities that run on a computer with internet connection to facilitate home therapy. Patient must wear anaglyph glasses. Visual stimuli consists in dichoptic Gabor Patches presented to the amblyopic eye. Frequency is adjusted to actual patient visual acuity, and contrast to actual patient performance (contrast sensitivity). A band-filtered noise mask at the same frequency than the Gabor patch is presented to the fellow eye in certain ocassions.

PEDIG (Pediatric Eye Disease Investigator Group) recommended amblyopia treatment. Consist on covering a child's better-seeing eye with a patch for 2 hours per day for mild and moderate amblyopia or 6 hours per day for severe amblyopia
