Klebsiella keratitis presenting as a ring infiltrate in an adolescent girl

The purpose of the study was to report a unique case of Klebsiella keratitis presenting as a ring infiltrate in an adolescent girl. A 16-year-old girl presented with decreased vision in the right eye preceding an episode of fever with a rash associated with burning micturition. The patient was examined after taking appropriate consent. The slit-lamp examination revealed a ring-shaped corneal infiltrate with an epithelial defect in her right eye. Corneal scrapings were sent for microbiological evaluation which revealed Gram-negative rods and culture identified it as extended-spectrum beta-lactamase-producing Klebsiella pneumoniae colonies. The patient showed a good response to topical fortified amikacin and tobramycin. For her systemic complaints, the pediatrician did a thorough investigative workup out of which blood culture showed growth of K. pneumoniae. Hence, intravenous antibiotics were given based on the antibiogram report and the patient recovered. After 2 weeks, a paracentral infiltrate in her left eye was noted followed by anterior uveitis. The patient responded well to the topical course of steroids along with aminoglycosides. Four months later, she had a recurrence of anterior uveitis in the right eye preceded by fever. Blood investigations were negative. Hence, a diagnosis of recurrent uveitis secondary to endogenous infection was made and the patient was successfully treated with a short course of topical steroids. The patient is on follow-up for the past 6 months and maintaining the best-corrected visual acuity of 20/20 OU with normal intraocular pressure and quiet anterior chamber (AC). This is the first clinical report describing a ring infiltrate in endogenous Klebsiella keratitis and emphasizes thorough workup for prompt treatment.
