Three days after the patient's initial exposure, his ocular pain increased and his best-corrected visual acuity declined to 20/60 OD and 20/125 OS. He had significant conjunctival hyperemia without purulent discharge, which was greater in the left eye than the right. There was 3+ punctate epithelial erosions in the right cornea and an 8×7-mm central epithelial defect associated with a peripheral stromal ring infiltrate in the left eye (Figure 2). There was a 1+ anterior chamber reaction in the left eye but normal intraocular pressure and posterior segment examination results in both eyes. Cultures for bacteria, viruses, fungi, and Acanthamoeba organisms were performed. He was empirically given prednisolone acetate, 1%, drops 3 times a day, fluorometholone, 0.1%, ointment at bedtime, and moxifloxacin, 0.5%, drops 4 times a day as well as oral doxycycline and ascorbic acid.
