Operant discrimination task evaluates stereopsis performance in various visual impairments, suggesting binocular factors matter more than visual acuity.
Stereopsis performance was assessed in 88 optometric patients using an operant match‐to‐sample discrimination task involving random dot stereograms (RDSs). All normals passed the RDS test, and all constant strabismics without amblyopia, microtropes, and amblyopic strabismics failed. Only a portion of anisometropia amblyopes, intermittent strabismics, and ocular‐pathology patients passed. The findings were interpreted as indicating that stereopsis with a RDS may be better predicted and explained in terms of binocular fusion and bifoveal alignment than by visual acuity.
