Normative Values of Various Pentacam HR Parameters for Pediatric Corneas

Purpose: To provide a normative database of several Pentacam parameters for a healthy pediatric population. Methods: This was a retrospective study conducted at Al Watany Eye Hospitals, Cairo, Egypt. We explored the Pentacam HR database and collected the data of 432 normal right eyes of children and teenagers aged 3 to 18 years. The subjects were classified into the following 3 groups: group 1 (3–6 years, 17 eyes), group 2 (6–12 years, 126 eyes), and group 3 (12–18 years, 289 eyes). The parameters of the study cohort were compared with those of a healthy adult cohort. Results: The mean age of the study cohort was 13.5 (13.2–13.8) years. There were significant differences in the following indices among the 3 age groups: anterior chamber (depth and volume), curvature (index of height decentration, index of vertical asymmetry, and center keratoconus index), elevation (front and back elevations from the best fit toric ellipsoid), and pachymetric (minimum and average pachymetric progression indices and average Ambrosio relational thickness) parameters (P values 0.001, 0.001, 0.002, 0.04,
