Abstract
Here, we describe a case of keratitis caused by Aspergillus terreus in an 80-year-old immunocompetent woman 1 month after uneventful cataract surgery. The patient presented with decreased visual acuity (20/50) and severe pain in her right eye. Examination revealed a 3.5 × 4.5 mm white-colored deep stromal infiltration located on the temporal corneal tunnel incision. Corneal scraping samples were obtained for cytological and culture examinations. The cinnamon-brown colonies consisting of a dense felt of conidiophores were identified as A. terreus using molecular data. Using CLSI M38-A2 microdilution method, minimum inhibitory concentration values of amphotericin B, itraconazole, voriconazole, and posaconazole were determined to be 2, 1, 0.25, and 1 μg/ml, respectively, and minimum effective concentration values of caspofungin and anidulafungin were ≤0.03 and ≤0.03, respectively, at 48 h for the A. terreus strain. Antifungal therapy was started as topical 1 % voriconazole drops hourly and 5 % natamycin ointment five times a day; however, corneal infection and melting progressed despite the ongoing intensive treatment and visual acuity dropped to the 20/200 level at the end of the first week. Amniotic membrane transplantation was performed to promote corneal healing. Topical medication was tapered and discontinued within 2 months based on the clinical features. The ulcer healed with scarring and vascularization, and visual acuity improved to 20/50. In conclusion, A. terreus is a very uncommon cause of mycotic keratitis and is especially rare after cataract surgery. We suggest that early and accurate diagnosis and appropriate treatment of A. terreus keratitis may have a major impact on preventing severe disease complications.
