Improved, non-invasive techniques for the diagnosis, classification and monitoring of patients with systemic sclerosis (SSc) are needed. One potential technique for quantifying the extent of cutaneous sclerosis in these patients is optical coherence tomography (OCT).1 ,2 Recently, Abignano et al3 suggested the use of OCT as a feasible and reliable technique to evaluate skin fibrosis in SSc. Based on that initial work, the aim of this study was to evaluate OCT images and compare the findings with the modified Rodnan skin score (mRSS) in patients with SSc.
Thirty-three Brazilian patients with SSc (28 women; mean age 46.1 years; range 19–71 years) were recruited and fulfilled criteria for SSc proposed by American College of Rheumatology (ACR), 19804 or ACR/European League Against Rheumatism, 2013.5 Patients were classified into limited SSc (n=18) and diffuse SSc (n=15) groups. The mean disease duration was 9.7 years (median 8 years, range 2–26 months). Thirty-five healthy control (HC) (28 women, …
