Abstract

Amblyopia is a leading cause of vision loss.^1,2 Since early identification and treatment of amblyopia may lead to more favorable acuity outcomes, considerable attention has been paid to the development of amblyopia screening techniques.^3,4 The direct measurement of visual acuity in very young and preverbal children can be time consuming in the context of mass screenings^5-8, expensive⁹, and may tend to underestimate the incidence and magnitude of amblyopia.⁶ Therefore, most screening methodologies are based on the identification of amblyogenic factors (i.e., strabismus, refractive errors and media opacities).
