Under a general anesthetic, the right eye was examined and found to have mild, diffuse corneal edema, hyphema and a 3mm diameter focal area of stromal abscessation that was partially epithelialized (Fig. 1).
Cytology of affected corneal tissue in case 1, demonstrating filamentous fungal hyphae typical in appearance of Aspergillus spp.

The following day, under a general anesthetic, the affected eye was assessed by an ophthalmologist (AOR) and was found to have diffuse corneal edema and an ulcerated 4mm diameter plaque over the axial cornea with corneal neovascularization from the dorsal limbus and aqueous flare (Fig. 3).
