Central Corneal Thickness in Patients With Systemic Sclerosis: A Controlled Study

Abstract

Purpose: To compare the central corneal thickness (CCT) of patients with systemic sclerosis (SSc) and control subjects. Methods: The study group comprised 37 consecutive patients with SSc, and the control group comprised 23 healthy individuals similar in age and sex. CCT value was measured by ultrasound pachymetry. Results: In the SSc group, the mean CCT in the right eye was 534.9 +/- 33.5 mu m and 536.9 +/- 32.4 mu m in the left eye. In the control group, the mean CCT was 533.0 +/- 32.9 mu m in the right eye and 533.1 +/- 33.6 mu m in the left eye. The mean CCT was not significantly different in the SSc group compared with the control group for both the right (P = 0.83) and left (P = 0.67) eyes. Conclusions: CCT measurements do not significantly differ in patients with SSc compared with healthy control subjects.
