Bacterial keratitis after nonpenetrating glaucoma surgery

A 68-year-old woman had uneventful deep sclerectomy with a collagen implant in the left eye that was complicated by infectious keratitis 2 weeks later. Corneal scraping revealed the presence of Staphylococcus aureus. The patient responded to topical antibiotic treatment, and the corneal infiltration resolved, leaving a corneal scar. Bacterial keratitis may occur after nonpenetrating glaucoma surgery and should be included in the list of early postoperative complications.
