Measuring suppression size and its implications for amblyopia management

Greater improvement in Grade 1 binocular vision compared with Grade 3 (stereoacuity) suggests a hierarchical recovery of binocular function in amblyopia. Additional therapy sessions may be considered to improve stereoacuity once suppression size is reduced to ≤1°. Measurement of SMP, alongside visual acuity and stereoacuity, may provide additional insights for amblyopia management.
