Survival after transplantation of corneas from a rabies-infected donor.

PURPOSE: To examine the tissue samples of 2 corneal recipients from a rabies-infected donor for the presence of rabies to explain their survival. METHODS: Interventional case series with a review of the literature. The explanted corneal donor buttons were examined via nested reverse transcriptase polymerase chain reaction. The patients were followed up ophthalmologically and neurologically. Antirabies antibodies were measured in blood samples, and skin biopsies were examined by direct fluorescent antibody staining. RESULTS: Two patients received corneas from the same multiorgan donor. Six weeks after transplantation, 3 of the donor's organ recipients became symptomatic and rabies virus was confirmed in tissue from the donor's central nervous system. Immediately, both the corneal recipients underwent active and passive postexposure treatment. The corneal buttons were replaced. Examination of the explanted donor corneas, skin biopsies, and serum and saliva samples showed no signs of rabies infection. The 2 corneal recipients were followed up at our hospital and, to date, are without symptoms of infection. CONCLUSIONS: Transmission of the potentially deadly rabies virus by corneal transplantation has been described previously. To our knowledge, this is the first report in which no rabies virus transmission occurred without immediate postexposure treatment.

Recurrent granular dystrophy of the cornea: an unusual case.

PURPOSE: To describe a case of severe corneal granular dystrophy with clinicopathologic and molecular genetic findings. METHODS: The DNAs of a 53-year-old male patient suffering from corneal granular dystrophy and nonaffected family members were analyzed by molecular genetic methods. Clinical features, and histopathologic and immunohistochemical findings from the penetrating keratoplasty specimen, are described. RESULTS: Histopathologic and molecular genetic findings confirmed the diagnosis. A new genetic polymorphism is described. Histopathologic evidence supports the assumption of the epithelial origin of the described dystrophy. CONCLUSIONS: A severe course of corneal granular dystrophy can be present in the absence of evidence of a homozygous mutational status, or a novel mutation. Molecular genetic analysis revealed a new polymorphism in this patient. The histopathologic findings support the assumption of an epithelial origin of the granular corneal deposits. Phototherapeutic keratectomy and penetrating keratoplasty may improve vision, but cannot prevent recurrence of the disease.
