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

Purpose To evaluate the usefulness of serial in vivo confocal microscopy (IVCM) examinations to measure hyphal density for monitoring the treatment success among patients with fungal keratitis, and to compare the hyphal diameter as well as branching angle as a way of differentiation between Aspergillus and Fusarium species observed in IVCM.
