Incidence, Risk Factors and Complications of Ocular Graft-Versus-Host Disease Following Hematopoietic Stem Cell Transplantation

center dot PURPOSE: The purpose of this research was to evaluate the incidence, risk factors, and complications of ocular graft-versus-host disease (GVHD) in a large single-center study.center dot DESIGN: Retrospective observational case series.center dot METHODS: This study included 283 patients who underwent hematopoietic stem cell transplantation (HSCT) between 2005 and 2020. Ocular GVHD was diagnosed according to International Chronic Ocular GVHD Consensus Group criteria. Potential risk factors for ocular GVHD were evaluated using the Cox proportional hazards model.center dot RESULTS: The cumulative incidence of ocular GVHD was 19.7% at 1 year, 29.3% at 2 years, 40.7% at 3 years, 47.2% at 4 years, and 49.7% at 5 years. Ocular GVHD was significantly associated with recipient age (hazard ratio [HR]: 1.228; 95% confidence interval [CI]: 1.033-1.459; P = .020); female sex (HR: 1.797; 95% CI: 1.195-2.703; P = .005); peripheral blood stem cell use (PBSC) (HR: 2.079; 95% CI: 1.268-3.411; P = .004); and previous acute GVHD (HR: 1.276; 95% CI: 1.073-1.518; P = .006). Ocular complications after HSCT included cataract, corneal ulcer, corneal perforation, lacrimal obstruction, herpetic keratitis, and cytomegalovirus retinitis.center dot CONCLUSIONS: Half of patients developed ocular GVHD in the 5 years following HSCT. Older age, female sex, use of PBSC, and acute GVHD disease were significant predictors of ocular GVHD. Hematologists and ophthalmologists should be aware of its vision threating complications.
