Abstract Details

Purpose:

The aim of this study is to determine the mean central corneal thickness(CCT) among a normal Iraqi population and to correlate between CCT and age, gender, refraction, and corneal curvature.

Setting:

Ibn Al-Haitham Teaching Eye Hospital / BAGHDAD /Iraq

Methods:

This cross-sectional study was carried out at Ibn Al-Haitham Teaching Eye Hospital. A total of 418 eyes from 209 healthy individuals with an age range from 20 to 75 years were studied. CCT was measured by ultrasound pachymeter. Refraction was measured using an auto-refractor and confirmed by trial lenses and retinoscopy to calculate the spherical equivalent. Corneal curvature was measured using an auto-refracto-keratometer to calculate the average corneal curvature (AVK).

Results:

The mean CCT was 543.95�Â�±32.58 �Î�¼m with a range from 422 to 636 �Î�¼m. CCT was not affected by gender. CCT significantly negatively correlated with age and AVK. CCT sig�Â�¬nificantly positively correlated with the spherical equivalence

Conclusions:

Among an Iraqi population, CCT significantly decreased with age. Myopics had significantly thinner corneas. There was weak but significant negative correlation between CCT and corneal curvature. We recommend further studies about the relationship between central corneal thickness and other ocular parameters in Iraqi population such as the axial length.
