Fungal keratitis caused by rare organisms

Purpose: To report two rare cases of filamentous fungal keratitis. Methods: Two non-consecutive patients presented with suspicious fungal keratitis. After performing the smear and culture, medical therapy was started for them. They underwent slit photography and in vivo confocal microscopy (IVCM) in their follow-up visits. Results: The patients were 33-year-old and 56-year-old farmer men. They both mentioned a history of ocular trauma by plants. During their follow-up visits, corneal infiltration density and fungal hyphae density decreased in slit-lamp biomicroscopy and IVCM, respectively. The corresponding organisms were Pseudallescheria boydii (P. boydii) and Colletotrichum coccodes. Conclusions: It is important to be aware of these rare organisms and their antibiotic susceptibility. There was not any specific confocal feature for the presented fungal keratitis that was different from other filamentous fungal hyphae; however, confocal scan is a good choice to follow the response to the treatment.
