To report for the first time a case of interface Scopulariopsis gracilis fungal keratitis following Descemet’s stripping automated endothelial keratoplasty (DSAEK) with a contaminated graft.
A 57-year-old man with bilateral keratoconus and previous bilateral penetrating keratoplasties (PK) developed graft failure in association with marked corneal ectasia. He underwent a successful DSAEK. Unfortunately, a contaminated graft was transplanted and the following morning we were contacted by the eye bank to inform us a slow-growing fungus had been detected in the culture plates inoculated with dextran solution used to store the issued corneoscleral button. Immediate patient review revealed four infiltrates in the interface between the donor and the recipient tissue. The patient returned to theatre for the removal of the infected graft and was successfully treated with topical amphotericin 0.15%, voriconazole 1% and oral voriconazole and later oral itraconazole. Two intracameral injections of 5 µg in 0.1 ml of amphotericin B were also performed.
A reference laboratory cultured and identified the fungus as Scopulariopsis gracilis species. The patient responded to treatment and eventually achieved a spectacle-corrected logMAR visual acuity of 0.3 following a delayed PK.
Scopulariopsis gracilis fungal keratitis is a rare infection, and the species can be difficult to eradicate. This is the first case report of an infection secondary to a contaminated graft with the species, and we report its successful treatment with an excellent visual outcome.
