Interface fungal keratitis after endothelial keratoplasty: a clinicopathological report.

The authors report two cases of interface fungal keratitis following Descemet's stripping automated endothelial keratoplasty (DSAEK). Two patients developed culture-proven interface keratitis with Candida albicans and Candida glabrata following DSAEK. Both patients presented with white interface opacities at approximately 1 month after uncomplicated DSAEK. Adjunct confocal microscopy identified fungal elements prior to surgical therapy. A penetrating keratoplasty was performed in both cases after failed medical therapy with fungal elements confirmed by corneal histopathology. Interface fungal keratitis must be recognized as a potential complication of endothelial keratoplasty. Surgeons should consider corneal donor rim cultures on all endothelial keratopathy cases and confocal microscopy on cases with new interface opacities in the early postoperative period. These measures may lead to early identification and treatment of fungal interface infections.
