    Abstract:
    AIM: To evaluate the incidence and clinical course of corneal complications in patients with severe dry eye syndrome after hematopoietic stem cell transplantation (HSCT). PATIENTS AND METHODS: 50 consecutive patients (aged 9-65 years; average=42+/-11 years) with Sjögren-like syndrome after hematopoietic stem cell transplantation were examined. In order to assess the severity of the dry eye syndrome, the frequency of blinking and break-up time were determined and Schirmer-I, fluorescein,and rose bengal tests were carried out. Biopsy and histological examination were performed in cases with suspected conjunctival graft-versus-host reaction. RESULTS: Patients with Sjögren-like dry eye syndrome were referred within an average of 13 months after HSCT (SD+/-20 months).The follow-up was up to 83 months (mean: 10.2 months,SD+/-14.97). Of the 50 patients 15 developed severe corneal complications with significant loss of vision which resulted in enucleation of the eye in 1 patient. Of these 15 patients 4 had a viral and 2 a bacterial keratitis,7 had trophic corneal thinning and sterile ulcers. Two patients had limbal stem cell insufficiency or pseudomembranous conjunctivitis, both due to conjunctival graft-versus-host reaction. Another patient developed a toxic keratopathy, probably induced by cyclosporin A eye drops. Of 50 patients 35 presented with signs of an inactive or active conjunctival graft-versus-host reaction which could be proven histologically in 26 patients. DISCUSSION: Patients with Sjögren-like dry eye syndrome after hematopoietic stem cell transplantation are at high risk to develop corneal complications.These complications may result from an aggressive extension of the graft-versus-host reaction towards the conjunctiva and/or the lacrimal gland and seem to occur more often during the period of reduction of systemic immunosuppressive therapy.Furthermore, infectious as well as trophic or toxic corneal complications may be supported by local immunosuppressive therapy. We suggest frequent ophthalmological checks of patients receiving hematopoietic stem cell transplantation who need local immunosuppressive therapy or are in the phase of reduction of systemic immunosuppressive therapy
