Evaluation of corneal epithelial thickness mapping via spectral-domain OCT in patients after allogeneic haematopoietic stem cell transplantation

The CET map demonstrated that post-HSCT patients with or without chronic oGVHD had a relatively thicker corneal epithelium in the central and inferior regions. These changes were correlated with lid margin morphology. This SD-OCT mapping provides a better understanding of early corneal epithelial alterations following HSCT and identifies potential biomarkers for early diagnosis.
