Purpose: To compare the refractive errors, keratometric and biometric variables among the patients with anisometropic amblyopia and to evaluate the relationship between the depth of amblyopia and the degree of anisometropia and binocularity.

Study Design: A prospective cohort, clinical study.

Setting: Afyon Kocatepe University Hospital, TR.

Methods: Thirty-eight anisometropic amblyopic patients had detailed ophthalmological examinations including keratometry and axial length measurements and the results were compared.

Results: In all subjects, there is a positive correlation between axial length measurement and anisometropia was found to increase with an increase in axial length (p = 0.000). The depth of amblyopia was not statistically related to the anisometropic spherical value (p = 0.09). Nevertheless, in the anisometropic subjects with suppression, the spherical refractive error was significantly higher (p = 0.009). Keratometric measurements were not significantly different in amblyopic eyes in comparison to the sound eyes (p = 0.15).

Conclusions: In anisometropic subjects, we found that there was a significant relationship between the suppression and the axial length. We have shown that axial length is a significant predictive value in terms of binocular vision functions.
