Corneal Biomechanics in Non-infectious Uveitis Measured by Corvis ST: A Pilot Study

Abstract

ABSTRACT Purpose To assess differences between corneal biomechanical properties in patients with non-infectious uveitis and healthy subjects using CorVis. Methods 77 patients with non-infectious uveitis and 47 control subjects were recruited. Biomechanical parameters were measured: deformation amplitude (DA), A-1 length and A-2 length (L1, L2), A-1 velocity and A-2 velocity (V1, V2), peak distance (PD) and HC radius (highest concavity radius). AUC ROC and correlation between clinical variables and biomechanical properties were determined. Results Lower HC Radius and IOPb and higher DA and V1 was found in uveitis group. Statistical differences between cases using systemic medications and those with topical treatment were found in L1. Differences were showed between those cases with active and inactive uveitis in PD, DA, V2 and L2. The biomechanical parameter with the best discriminatory capacity of uveitis disease was HC Radius. Conclusion Differences in corneal biomechanical properties between non-infectious uveitis and healthy eyes were found.
