Corneal Transplant Rejection Following Durvalumab Therapy in a Patient With NSCLC: A Case Report.

We report the case of corneal transplant rejection in a 77-year-old male receiving durvalumab as consolidative therapy for stage IIIB non-small cell lung cancer (NSCLC). Following successful chemoradiation and initiation of durvalumab, the patient underwent a right corneal transplant for corneal dystrophy. Six months after an initially stable post-transplant course, he developed progressive visual decline culminating in graft failure 1 year later despite treatment with prednisone eye drops. This case adds to the limited evidence implicating immune checkpoint inhibitors (ICIs) in corneal graft rejection, emphasizing the need for multidisciplinary evaluation and close monitoring of corneal transplant recipients undergoing ICI therapy.
