Abstract Details


The aim of this study was to determine normative corneal densitometry related to age, gender, refractive error and keratometry in a large group of participants, measured by Oculus Pentacam® System


Innova Ocular Group, Spain


Three hundred and sixty seven patients (199 men; 165 women) participated in this study. All participants were subjected to an exhaustive ocular examination. Corneal densitometry was obtained with Oculus Pentacam®. Densitometry measurements were expressed in standardized grayscale units (GSU).


The mean corneal densitometry over the total area was 16.46 ± 1.85 GSU. For total densitometry the Pearson’s correlation coefficient was r = 0.542 (p < 0.001). Statistically differences men and women were found for the total area. When the cornea was divided in different depth layers, a significant correlation was found for all layers. However, when the cornea was divided in concentric annulus only was found a strong correlation of densitometry with age in 6-10 mm annulus (p < 0.001). No correlations were found between mean keratometry or spherical equivalent with corneal densitometry in any zone of the cornea.


This is the first report of normative corneal densitometry values related to age, keratometry and spherical equivalent measured with the latest Oculus Pentacam® system software. The corneal densitometry increases with age, but the corneal keratometry and the refractive parameters do not affect light scattering in the human cornea
