    Abstract:
    PURPOSE: To report the clinical course and management of graft-host interface Nocardia keratitis after Descemet membrane endothelial keratoplasty (DMEK). METHODS: A 70-year-old man presented with a corneal epithelial defect, stromal edema, graft infiltrate, and graft-host interface infection 5 months after an uneventful DMEK performed for bullous keratopathy in the left eye. Corneal scrapings from the margin of epithelial defect showed gram-positive bacillus, and the organism was identified as Nocardia asteroides. RESULTS: Intensive and appropriate topical and systemic antibiotic therapy resulted in complete resolution of infection. Three months later, the patient underwent a repeat DMEK, which resulted in clearing of corneal edema and improvement in visual acuity. CONCLUSIONS: Nocardia interface keratitis is a rare entity, which can occur after DMEK. Proper clinical evaluation and microbiological workup helped us in accurate diagnosis and management. Repeat DMEK after complete resolution of the infection resulted in good outcomes regarding corneal clarity and vision improvement.
