Tear Cytokine Analysis as a Prediction or Diagnostic Marker in Ocular GvHD

Investigate the profiles of tear cytokines in patients who underwent stem cell transplantation (SCT) and attempted to determine the applicability of tear cytokines in the diagnosis of chronic graft-versus-host disease (GVHD). Evaluate tear cytokines as biomarkers of chronic ocular GVHD severity.

Inclusion Criteria:

• The patients patients aged 20-60 years who visited the clinic 3-12 months after SCT were included in the study.

Exclusion Criteria:

• The patients with histories of ocular surgery; ocular injury; and ocular diseases such as ocular infection, allergy, and autoimmune disease, as well as patients with long-term use of topical ocular medications except artificial tears.
