Abstract

Purpose

This report assesses white-to-white corneal diameter, pupil diameter, central corneal thickness and thinnest corneal thickness values in a large sample of emmetropic subjects.

Methods

Three hundred and seventy-nine eyes of 379 young healthy emmetropic subjects were analyzed by means of scanning-slit corneal topography. The age of the subjects ranged from 18 to 53 years (mean ± SD = 29 ± 7). The mean of five consecutive measurements of the central corneal thickness, the thinnest corneal thickness, the white-to-white corneal diameter, and the photopic pupil diameter was recorded.

Results

The central corneal thickness ranged from 528 to 588 μm; the thinnest corneal thickness ranged from 504 to 574 μm; the white-to-white corneal diameter ranged from 11.5 to 12.3 mm; and the pupil diameter ranged from 3.0 to 4.7 mm. The central and the thinnest corneal thickness were positively correlated (r = 0.94, p < 0.001), and the pupil diameter was significantly higher in females (p < 0.001).

Conclusions

This study shows that there are no differences in white-to-white corneal diameter, central corneal thickness, and thinnest corneal thickness between emmetropic females and males. However, pupil diameters are greater in emmetropic females.
