Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 14 years or older who have undergone their first allogeneic stem cell transplant and are at least 100 days post-transplant with confirmed donor engraftment.

Probably not a fit

Patients who already have moderate-to-severe ocular surface disease before transplant or who have active ocular infection or other ocular conditions that interfere with assessment may receive limited or no direct benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, prospective observational study enrolling up to 340 patients who had an allogeneic stem cell transplant. Patients will undergo evaluations by hematology and ophthalmology teams and report outcomes themselves to understand the incidence, risk factors, and clinical course of chronic ocular GVHD after transplant. The study will track patient-reported outcomes and objective eye assessments over time to characterize the condition in routine clinical practice. No experimental treatments are given in this design; it aims to observe natural history and factors associated with outcomes. Results may help clinicians identify patients at higher risk and inform follow-up strategies.

Why it matters

Potential benefit: If successful, the study could improve understanding of chronic ocular GVHD and guide better monitoring and management to preserve vision and quality of life.

How similar studies have gone: Similar observational efforts have provided valuable insights into ocular GVHD patterns, though this study focuses on a structured, multicenter, patient-reported approach in a Chinese population.
