New treatments for amblyopia are being developed that emphasize the use of binocular visual stimulation as a means of improving not only visual acuity but also binocular function in both children and adults. These treatments use computer games played on a smartphone or computer tablet in which the contrast of the stimulus presented to the fellow eye is reduced to compensate for the decreased contrast sensitivity of the amblyopic eye. Theoretical arguments have been advanced for the superiority of this treatment over patching, and early results in uncontrolled trials performed in children and adults have shown improvements in visual acuity and stereoacuity (for references, see articles by the Pediatric Eye Disease Investigator Group1 and Kelly et al2).
