Comparison of perceptual eye positions among patients with different degrees of anisometropia

The aim of this study is to compare the perceptual eye positions (PEPs) among patients with different degrees of anisometropia.A total of 157 patients were recruited into this retrospective study. A detailed ophthalmic examination was conducted on each patient. The degree of refractive errors in the presence of astigmatism was converted into the degree of spherical equivalent (SE). Patients were divided into 3 groups according to the interocular SE difference: severe anisometropia group with interocular SE difference ≥2.50D, mild anisometropia group with interocular SE difference ≥1.00D and
