The ocular examination findings including visual acuity, meibomian gland dysfunction, corneal and conjunctival staining with severity, corneal scarring, tear film meniscus and breakup time, anterior and posterior segment examination findings, intraocular pressure, treatment given, punctual plugs used or not, and follow up response were collected.RESULTS: The five years cumulative incidence of o GVHD among post-transplant patients was 56.98%(95%CI 38.6%-71.7%). The potential risk factors assessed for developing ocular manifestation were age, gender, donor’s age, donor gender mismatch CD3 and CD34 infusion, while none of the correlates were identified as statistically significant risk factors of developing ocular manifestation. However, the incidence was statistically significantly different betweenpatients diagnosed with acute myelocytic leukemia and acute lymphocytic leukemia(P=0.038). The mean latent period to develop ocular symptoms was 20.5 mo. All patients had variable degree of dry eyes. None of the patients developed any posterior segment complication.CONCLUSION: The incidence of o GVHD is low in King Abdul-Aziz Medical City. This can be attributed to the preconditioning and immunosuppressive regime.展开更多
