Correlation of Anisometropia with Axial Length and Corneal Curvature: An Institution-Based Cross-Sectional Study.
Background: A difference of >1.00 dioptre (D) is the widely accepted criteria for anisometropia. An analysis of binocular characteristics in the anisometropic eye revealed that the most critical component was axial length (AL). The purpose of this study was to determine the correlation between AL an...

| Sumario: | Background: A difference of >1.00 dioptre (D) is the widely accepted criteria for anisometropia. An analysis of binocular characteristics in the anisometropic eye revealed that the most critical component was axial length (AL). The purpose of this study was to determine the correlation between AL and corneal curvature in anisometropes. Methods: This was a prospective institutionbased observational study. One hundred subjects with >1 dioptre anisometropia were included. All of the subjects underwent a comprehensive eye examination followed by corneal curvature (CR) measurement with a manual keratometer and axial length measurement using the Carl Zeiss IOL Master 500. Results: The mean ± SD of spherical equivalent refraction (SER) was 3.52±2.08 D. A positive correlation was found between SER and AL difference between both eyes (r=0.61; p=<0.001) and between SER and AL/CR ratio between both eyes (r=0.57; p=<0.001). Conclusions: AL is a relevant factor in anisometropic eye dioptric power disparities, with no significant relationship between CR and dioptric power. |
