Ocular Graft-versus-Host Disease: A Review

Graft-versus-host disease (GVHD) is a common cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Systemic findings involving the skin, gastrointestinal tract, and liver often overshadow the other manifestations of GVHD. Ocular surface disease remains the most common cause of long-term morbidity in GVHD. Herein, the etiology, pathophysiology, clinical manifestations, and treatment of acute and chronic systemic GVHD are reviewed, with a focus on ocular GVHD.
