HealthDay News — A case of Kingella kingae keratitis in an HIV-positive adult male is described in a letter to the editor published in Clinical & Experimental Ophthalmology.

Harry Yip and Mark Whiting, MBBS, from the Royal Victorian Eye and Ear Hospital in East Melbourne, Australia, present the case of K kingae keratitis in an adult. The patient was a 52-year-old HIV-positive male with a 2-day history of a painful, watery, red eye and a marked decrease in vision. The patient had a history of 1 week of orthokeratology lens use for myopia.

The authors observed a 1.5-mm diameter corneal ulcer, central corneal Descermet's membrane folds, and 2+ cells in the anterior chamber on examination. They performed a corneal scrape and commenced hourly ofloxacin and atropine sulfate. There was improvement on day 1, with only 1+ anterior chamber cells and a smaller stromal infiltrate. The epithelial defect had almost completely resolved by day 5 and the underlying infiltrate was smaller. Improvement continued on day 7 and vision had improved to 6/15 in the right eye. The epithelial defect had healed completely by day 21 and the patient's vision was 6/9 in the right eye.

"In conclusion, K kingae is a rare pathogen that may cause microbial keratitis in immunocompromised adults," the authors write. "Management is straightforward and prognosis is reasonable."
