RESUMO
Objectives: To evaluate the frequency and findings of dry eye associated with ocular graft-versus-host disease (GVHD) in pediatric hematopoietic stem cell transplantation (HSCT) patients. Materials and Methods: Retrospectively the records of pediatric patients with ocular GVHD were evaluated and ophthalmologic examination findings as well as Schirmer test results, tear film break-up time, and corneal staining grades were recorded. In severe dry eye patients topical cyclosporine-A was prescribed and the results were evaluated. Results: GVHD was detected in 51 (23.4%) of 218 HSCT patients, 4 of whom died during follow-up. Thirty (63.8%) of the remaining 47 patients had chronic ocular GVHD and 4 patients with severe dry eye were treated with topical cyclosporine-A with a median follow-up of 12.1 months. Severe dry eye symptoms and findings significantly improved in 2 patients. However, 1 patient had to stop treatment due to side effects. Conclusion: In children, chronic ocular GVHD is a common finding of GVHD after HSCT. Therefore, these patients should be examined periodically for dry eye.

Cytomegalovirus (CMV)-related corneal endotheliitis is an inflammation of the corneal endothelium caused by CMV. It may occur de novo or after ocular surgery in otherwise healthy individuals. In patients who have undergone keratoplasty, the differential diagnosis of viral endotheliitis and immune-related graft rejection is challenging due to the similar clinical findings. Here we report a patient who underwent penetrating keratoplasty and was using local and systemic immunosuppressive agents due to previous history of graft rejection. At postoperative year 4, ophthalmologic examination revealed localized corneal edema, coin-shaped keratic precipitates, and increased intraocular pressure, consistent with viral endotheliitis. Polymerase chain reaction revealed CMV-DNA amplification in the aqueous humor sample. Valganciclovir treatment was started and the symptoms improved in 2 months. It should be kept in mind that local or systemic immunosuppressants used after keratoplasty may trigger CMV reactivation. Anti-CMV treatment should be initiated immediately in patients with coin-shaped keratic precipitates.
