ABSTRACT

Purpose@#To report a case of keratitis caused by Brevundimonas diminuta/vesicularis.Case summary: A 20-year-old man presented with decreased visual acuity and glare in his right eye from 2 days earlier. At the first visit, slit lamp examination revealed a 1.5 × 1.5 mm2-sized stromal infiltration, an edematous cornea and endothelial deposits in the center of the right eye. Microbiological examinations were performed from corneal scrapings. Treatment was started with topical eye drops (fortified cefazolin, fortified tobramycin) as empirical antibiotics. After several days, the cultures revealed Brevundimonas diminuta/vesicularis. After treatment with empirical antibiotic eye drops, the symptoms and visual acuity improved. @*Conclusions@#We report a case of infectious keratitis caused by Brevundimonas diminuta/vesicularis, which has never previously been reported in the Republic of Korea.
