Values of White-to-White Corneal Diameter and Anterior Chamber Depth in Healthy Libyan Eyes Obtained with Pentacam Scheimpflug Imaging”
Abstract
Background: Accurate measurements of the depth of the anterior chamber and horizontal white-to-white (WTW) corneal diameter are essential for numerous clinical applications.
Aim: to determine the normative values of white-to-white corneal diameter and anterior chamber depth in a healthy Libyan population using Pentacam HR.
Methods: An observational cross-sectional study was carried out in Benghazi Teaching Eye Hospitals between December 2023 and February 2024, it involved100 individuals (200 eyes), with a mean age of 32.84±13.04 years (range17-74 years), the white-to-white corneal diameter and anterior chamber depth were measured using the Pentacam® HR.
Results:
The mean WTW distance was 11.71± 0.57mm (range=10.25 - 12.80mm), and the mean anterior chamber depth was 3.53± 0.43mm (range= 2.67 - 4.42mm). There was no statistical difference between genders regarding WTW distance and anterior chamber depth (p<.05)
The WTW corneal diameter and ACD were significantly inversely proportion correlatedwith age, there was a decrease in WTW diameter and AC depthwith increasing age, [F (2,97) =27.01, P=<.001, F (2,97) =13.20, P=<.001] respectively. The increase in WTW distance was associated with an increase in AC depth which was a highly positive statistically significant correlation (r=.741, p<.001).
Conclusion:
The Libyan’s mean WTW corneal diameter was lower, and the anterior chamber depth was deeper than other populations. A positive correlation between the WTW and ACD was found.
