Topical moxifloxacin causes corneal toxicity
Ophthalmologists at the Wake Forest Eye Center, Winston-Salem, North Carolina, have described two cases of the persistence of corneal ulcers after several weeks of treatment with topical 0.5% moxifloxacin. Both patients also exhibited signs of stromal edema but improved following a switch to gatifloxacin and corticosteroids. These cases show that moxifloxacin can interfere with the healing of corneal ulcers.
