Are There Any Changes in Corneal Biomechanics and Central Corneal Thickness in Fuchs' Uveitis?

Abstract

Purpose: To compare corneal biomechanics, intraocular pressure (IOP) and central corneal thickness (CCT) of 38 patients with unilateral Fuchs' uveitis (FU) with 42 healthy controls.

Methods: Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated and corneal-compensated IOP (IOPg and IOPcc, respectively) and CCT were measured.

Results: The mean CH, CRF, and IOPg of the involved FU eyes were significantly lower (9.5 ± 1.6, 9.0 ± 1.9 and 13.1 ± 4.3 mmHg) than contralateral eyes (10.1 ± 1.7, 9.9 ± 1.7 and 14.6 ± 3.4 mmHg), and controls (10.5 ± 1.5, 10.3 ± 1.5 and 14.8 ± 2.5 mmHg), respectively. There was no significant difference for mean IOPcc between involved FU or contralateral eyes and controls (14.8 ± 4.1, 15.5 ± 3.4 and 15.0 ± 2.7 mmHg). The CCT values correlated with CH and CRF in the involved and contralateral eyes.

Conclusions: Involved FU eyes had lower CH, CRF, and IOPg than contralateral eyes and controls, with no difference regarding IOPcc.
