Purpose: To determine the type of fixation in patients with anisometropic amblyopia without strabismus and find correlation between amount of anisometropia and eccentricity of fixation.
Material and methods: 100 patients with anisometropic amblyopia without strabismus were examined. The following data was obtained: visual acuity, type of fixation, refraction error after cycloplegia. Amount of anisometropia was calculated as the difference of spherical equivalents.
Results: Only 44% of patients demonstrated central fixation. The amount of amblyopia corresponded to eccentricity of fixation. For most cases (anisometropia up to 6D of SE) the amount of anisometropia did not correlate with eccentricity of fixation.
Conclusions: Simply difference of refraction must not be the only factor affecting development of anisometropic amblyopia.
