Purpose:
To present an unusual case of keratitis in a patient who wears hydrogel contact lenses that are replaced on a monthly basis. The agent isolated was Comamonas acidovorans, a species of Pseudomonas.
Methods And Results:
A 40-year-old patient who wears hydrogel contact lenses that are replaced on a monthly basis presented with a red eye. The patient reported that the eye had been red for 2 days. A peripheral corneal stromal infiltrate was found and Comamonas acidovorans was isolated in culture. The patient was initially treated with high-dose gentamicin. After the results of cultures and sensitivity studies were obtained, she was given ciprofloxacin, leading to the remission of the case.
Conclusions:
Comamonas acidovorans should be considered as a possible agent of keratitis in hydrogel contact lens wearers-a culture and sensitivity studies may be indicated.
