Abstract Details

Purpose:

To evaluate the association between light-coloured irides and dark-coloured irides and refractive error.

Setting:

Department of Ophthalmology, Kagithane State Hospital, Istanbul, Turkey

Methods:

788 eyes of 394 patients were included in the study. Eyes were classified into two groups; light-coloured irides (blue and green) and dark-coloured (black and brown) irides. Hazel and gray coloured patients were not included to the study. In fully automated mode, at least five autorefractions were performed with autorefractometer and a standardized value obtained. Spherical refractive error, cylindrical refractive error and anisometropia rates were compared between two groups.

Results:

Of the 197 patients included in the study 324 eyes (50 %) had light-coloured irides, and 324 (50%) had dark-coloured irides. Spherical and cylindrical refractive error prevalence of the group with light-coloured irides were more than the dark-coloured group, and the difference were not statistically significant (p>0.05). The difference between spherical and cylindrical refractive error mean values were not statistically significant (p>0.05). Anisometropia rates in between two groups was not statistically significant (p>0.05).

Conclusions:

Spherical and cylindrical refractive errors were found to be more prevalent among the participants with light-coloured irides. The study of iris colour may also contribute to the understanding of the refractive error mechanism and provide good suggestive evidence for studies on other eye diseases.
