To report a case of fusarium keratitis treated with only moxifloxacin 0.5% ophthalmic solution (Vigamox®, Alcon Laboratories, Inc., Ft Worth, TX, USA).

A 37-year-old healthy male patient experienced a right eye injury due to grain 7 days prior to presentation at our hospital with visual disturbance and ocular pain. A 2.7 × 4.3 mm sized corneal epithelial defect with irregular featherlike midstromal infiltration was observed, and slit lamp examination revealed a dry, rough texture. Thus a smear and culture were performed. Moxifloxacin 0.5% ophthalmic solution (Vigamox®) and lubricant were applied for treatment. Three days after using the eye solution, all clinical features improved. Seven days later, Fusarium species was identified in culture.

As standard treatment for Fusarium, the authors of the present study used an antifungal agent. Although hyphae were detected in culture, the use of only moxifloxacin 0.5% ophthalmic solution (Vigamox®) result in a satisfactory result and improvement in clinical features.
