A case of acute endothelial corneal transplant rejection following immunization with ChAdOx1 nCoV-19 coronavirus vaccine

A 28?year?old female who underwent an uneventful femtosecond laser enabled keratoplasty (FLEK) in her left eye presented with pain, redness, and blurring of vision in the operated eye two weeks after getting immunized with COVID?19 vector vaccine (ChAdOx1 nCoV19 Vaccine Recombinant COVISHIELD, AstraZeneca). Slit?lamp examination showed donor stromal edema with Descemet’s membrane folds and Khodadoust line (KP’s on endothelium) with anterior chamber cells and flare. The patient was diagnosed with acute corneal graft rejection and advised hourly topical steroids with cycloplegics and oral steroids. The patient responded to treatment and there was progressive reversal of graft rejection with the patient achieving best spectacle?corrected visual acuity (BSCVA) of 20/30 after five weeks of treatment. Our case highlights possible immune corneal graft rejection after COVID19 vaccination and the need to step up topical steroids before vaccination
