NCT05311514

Brief Summary

The study evaluates the efficacy and safety of allogeneic platelet lysate eye drops in patients with severe ocular graft versus host disease refractory to conventional systemic and local treatments. The corneal staining, conjunctival hyperemia, tear film break up time,Schirmer test and ocular surface disease index will be evaluated before and after allogeneic platelet lysate treatment. The safety of allogeneic platelet lysate treatment will be also assessed.
