CHRONIC EXOGENOUS EXOPHIALA DERMATITIDIS ENDOPHTHALMITIS

摘要

Purpose: To describe a case of chronic exogenous Exophiala dermatitidis endoph-thalmitis. Methods: Retrospective chart review and case report. Results: A 60-year-old man with history of chronic herpes zoster keratitis complicated by secondary fungal keratitis treated with penetrating keratoplasty presented with a white cataract, chronic anterior uveitis, and counting fingers vision in the left eye. Combined cataract extraction and diagnostic vitrectomy revealed positive cultures and polymerase chain reaction-based testing for E. dermatitidis-the same organism responsible for the keratitis. The patient was treated with multiple oral, intravenous, and intravitreal antifungal agents. Ultimately, the comeal infection recurred and the patient elected to undergo enucleation. Filamentous fungi consistent with E. dermatitidis infection were identified in the cornea of the enucleation specimen. Conclusion: Although rare, Exophiala species can cause exogenous endophthalmitis. Chronic endophthalmitis should be suspected in patients who develop persistent intraocular inflammation after infectious keratitis.
