IRB-approved retrospective chart review was conducted for the following data: demographic information, ocular surface disease index (OSDI), corneal fluorescein staining (CFS), and treatment(s) used. Differences by site were assessed using Pearson’s Chi-Square tests and two-sample t-tests; differences by time were assessed using paired t-tests.Results: At baseline, Clinic 1 (C1) patients had a worse mean OSDI score (47.8 vs 36.3, p = 0.011) and CFS in both OD (1.3 vs 0.8, p = 0.005) and OS (1.3 vs 0.6, p < 0.001) compared to Clinic 2 (C2). Comparing baseline to endpoint, C1 patients experienced an improvement in OSDI (− 17.26, p < 0.001), CFS OD (− 0.50, p < 0.001), and CFS OS (− 0.51, p < 0.001) at C1. Change in OSDI, CFS OD, or CFS OS was not statistically significant at C2. Despite similar follow-up length, C1 demonstrated more clinic visits (10.4 vs 3.4, p < 0.001) and more treatment trials (4.9 vs 2.4, p < 0.001) compared to C2. Punctal plugs (85.5% vs 61.2%, p = 0.002), punctal cautery (69.7% vs 28.6%, p < 0.001), topical steroids (72.4% vs 22.4%, p < 0.001), and autologous serum tears (AST) (52.6% vs 8.2%, p < 0.001) were used more frequently at C1 than at C2.Conclusion: oGVHD patients at C1 experienced significant improvement in OSDI and corneal fluorescein staining and compared to patients at C2, had more frequent follow-up and use of punctal plugs, punctal cautery, topical steroids, and AST.Keywords: graft-versus-host disease, GVHD, chronic GVHD, dry eye disease, ocular GVHD, keratoconjunctivitis sicca, KCS
