Sixty-seven patients undergoing allogenic bone marrow transplantation (BMT) were examined before and at regular intervals for up to 87 months (1-87 months, mean 18) after transplantation. Within a period of 1-39 months, 14 of these patients died (11 male, 3 female; age at BMT 16-46y). Five of these patients died within the first 100 days. They showed no eye involvement; three patients had intraretinal hemorrhage, in one case of squamous blepharitis and filiform keratitis developed during chronic graft-versus-host disease (GVHD). In contrast, 22 of 53 (41.5%) surviving patients (30 male, 23 female; age at BMT 1-47y) were found to have ocular involvement. Before BMT only two cases of retinal hemorrhage and central chorioretinal scars each were detected. During the stage of acute GVHD (up to day 100), nine patients were free of ocular manifestations. However, 16 of the 20 patients with chronic GVHD showed ocular involvement; 14 (70%) had reduced tearflow, ten had severe keratoconjunctivitis sicca, four suffered from sterile corneal ulcerations. Bilateral cataracts were detected in 11 patients, nine of whom only had minimal posterior subcapsular opacification, possibly resulting from highdose steroid medication. One additional case presented with bilateral multifocal recurrent chorioretinitis and panuveitis. The fundus lesions appeared some months after BMT (before cyclosporin-A treatment started) and recurred during systemic treatment. All patients undergoing allogenic BMT, especially when treated for severe chronic GVHD, require regular ocular observation to avoid complications such as keratoconjunctivitis sicca at an early stage, as late complications are often severe and hardly amenable to conservative or surgical treatment.

A 33-year-old woman underwent bone-marrow transplantation following radiation and chemotherapy for chronic myelocytic leukemia (CML); immunosuppressive therapy was continued for graft-versus-host disease. Five months after successful transplantation, she developed necrotizing retinitis in both eyes with rapid progression over the following weeks. Due to her immunosuppressed state the patient developed pneumonia and died. Postmortem evaluation of the retinal lesions in both eyes disclosed infection by Toxoplasma gondii, which was also found in the brain and myocardium. Multiple viable toxoplasmic cysts were observed at the transition zone from a necrotic to a normal retina. Additionally, cysts of Toxoplasma gondii a normal retina. Additionally, cysts of Toxoplasma gondii were seen in the adjacent intact retina and in areas of necrosis with almost complete absence of retinal or choroidal inflammation. Toxoplasmosis should therefore be considered along with fungi and viruses in the differential diagnosis of necrotizing retinochoroiditis in immunocompromised patients.
