Abstract

We report the results of a new amblyopia treatment device used in 7 children with anisometropic amblyopia. The Occlu-pad was created by removing the polarizing film layer from the liquid crystal display screen of an iPad Air (Apple Inc, Cupertino, CA). Patients were asked to wear special glasses that contained a polarizing filter for their amblyopic eye and a light reduction filter for their normal eye and instructed to play an amblyopia training game displayed only to the amblyopic eye. In 5 patients corrected distance visual acuities in the amblyopic eyes improved after 2 months' treatment on average by 0.38 (logarithm of the minimum angle of resolution).
