Nocardia keratitis after laser in situ keratomileusis: clinicopathologic correlation.
A case of Nocardia asteroides keratitis occurring 3 weeks after laser in situ keratomileusis (LASIK) in a nontraumatized eye is reported. The patient presented with decreased vision, inflammation, and stromal melting of the LASIK flap, discrete infiltrates, and an anterior chamber cellular reaction. Cultures for acid-fast bacteria grew Nocardia asteroides after 5 days. Infection progressed despite treatment with topical antibiotics and eventually required penetrating keratoplasty (PKP). Postoperatively, the patient was placed on moxifloxacin, a fourth-generation flouroquinolone. The patient experienced a recurrence of Nocardia keratitis at the graft-host interface 2 months after the PKP. This eventually resolved with a combination of topical moxifloxacin and imipenem therapy.
