Evaluation of Amblyopia Protocols Using a Dichoptic Gabor Videogame Program

Interest in developing alternative methods for the treatment of amblyopia (lazy eye) has long been a topic of interest among clinicians and researchers. Occlusion or penalization of fellow eye do not always provide the desired visual acuity improvement. Moreover, occlusion is associated with a high risk of recurrence and non-compliance. Here, it is presented a protocol of a randomized clinical trial to evaluate the safety and clinical efficacy of a novel home-based system, based on a computer game. The goal of this prospective clinical trial is to compare in visual acuity improvements in patients with amblyopia, following conventional patching therapy or this novel computer-based therapy. The main questions it aims to answer are: * Does computer-based therapy equal or improve patching therapy? Can it be used as an alternative to patching? * Does computer-based therapy used in combination with pathching solve amblyopia when patching fails alone (persistent amblyopia)? Participants will be divided in two groups according to the previous occlusion o penalization of fellow eye. Both groups will be divided in two subgroups, experimental and control. Researchers will compare subgroups outcomes in order to asses this novel approach.

Inclusion Criteria: * The sample will be made up of children with amblyopia from 4 to 12 years old (amblyopia will be defined as the best corrected visual acuity less o equal to 0.8 in decimal units or \> 2 lines of difference between both eyes). Strabismus inclusion criteria will be \< 25 prismatic diopters, with a deviation ≥ 2 prismatic diopters. Exclusion Criteria: * Subjects with nystagmus, ocular pathology o cognitive delay will be excluded.
