The relationship between amblyopic eye/worse eye logMAR visual acuity and stereoacuity (seconds of arc or ″) for amblyopic and control subjects. Amblyopic subjects are grouped by the associated amblyogenic factor: strabismus, anisometropia, or mixed (i.e., strabismus and anisometropia). No measurable stereopsis indicates stereoacuity worse than 800”, which is the coarsest stereoacuity level that can be assessed with the Randot Preschool Stereoacuity Test. The symbol groupings that represent the associated amblyogenic risk factors are shifted horizontally at stereoacuity levels of 800” and “no measurable stereopsis” to allow for ease of viewing.
