This review was carried out to study the frequency, and severity of ocular surface involvement at the setting of allogeneic hematopoietic stem cell transplantation and subsequent graft-versus-host disease (GVHD) and evaluate the clinical outcomes of newer treatments. Ocular involvement has been reported in 60-90% of patients with chronic GVHD. Although dry eye is the most frequent finding occurring in the great majority of patients (up to 90%), posterior segment complications are also not infrequent, seen in 12.8% of patients after bone marrow transplantation. Anti-inflammatory treatments particularly T-cell suppressants seem to have a beneficial effect in managing GVHD. Corticoteroids, calcineurin inhibitors, such as cyclosporine and tacrolimus, as well as antifibrotic agents such as tranilast are available options for topical application. Cyclosporine ophthalmic drop seems to be a well tolerated and effective treatment modality; favorable results have been demonstrated with increased dosage. GVHD is an increasingly frequent cause of ocular surface morbidity with the potential of visual loss from corneal involvement. Early diagnosis and aggressive local as well as systemic treatment can be vision saving.
