ABSTRACT
Objective To estimate the role of the posterior corneal parameters measured by Pentacam in screening subclinical keratoconus.Design Retrospective case-controlled study.Participants Forty five healthy subjects(73 eyes),14 keratoconus patients (20 eyes),43 subclinical keratoconus patients(58 eyes).Methods Based TOPOLYZER and biomicroscope signs,eyes were diagnosed as subclinical keratoconus and keratoconus to compare the differnces of related posterior corneal parameters provided by Pentacam in normal eyes and subclinical keratoconus or keratoconus eyes.Main Outcome Measures Back-Diff(6 mm) max,Back-Diff(6 mm )min, Back-Difference(6 mm),Back-Rmin,Back-Astig.Results The parameters which were statistically different between normal corneas and clinical keratoconus,normal corneas and subclinical keratoconus include Back-Diff(6 mm)max(P
