Comparison of binocular visual function among patients with different types of anisometropia

The study revealed no significant difference in visual function between anisometropic amblyopia patients who achieved normal BCVA (≤0.0 LogMAR) and non-amblyopic anisometropic controls. However, all forms of anisometropia demonstrated varying degrees of impairment to binocular fusion and stereopsis, with hypermetropic anisometropia showing the most pronounced deficits, particularly in near stereopsis. Notably, vertical PEP instability may contribute to the progression of hyperopic anisometropia.
