The use of in vivo confocal microscopy to track treatment success in fungal keratitis and to differentiate between Fusarium and Aspergillus keratitis.

Decreasing hyphal density in serial IVCMs might be used as an indicator to predict the successful response of fungal ulcers to treatment. Branching angle is not different between Aspergillus and Fusarium keratitis. The mean hyphal diameter is significantly lower in the treatment failure group.
