[In vivo confocal microscopy in the diagnosis of fungal keratitis: case report].

The authors describe a case of fungal keratitis that the in vivo confocal microscopy helped in the diagnosis and follow-up. Confocal microscopy was done in a patient's ulcer that did not improve with several topical medicines. Corneal scrapings were obtained and culture results were without conclusion. We observed hyphae and infectious collections on confocal microscopy. New corneal culture showed Fusarium sp ten days after confocal diagnosis.
