title: Central corneal thickness in patients with systemic sclerosis: a controlled study.
abstract: OBJECTIVE
  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 μm and 536.9 ± 32.4 μm in the left eye. In the control group, the mean CCT was 533.0 ± 32.9 μm in the right eye and 533.1 ± 33.6 μm 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.
