Snellen visual acuity was hand motion close to the face with accurate projection of rays in the right eye and 6/6 in the left eye. Slit-lamp examination revealed a near total epithelial defect with corneal infiltrates of 8x8 mm extending up to 1/2 of corneal thickness with circumciliary congestion and lid edema (Figure 1 (Fig. 1)).

Confocal microscopy was performed, which revealed the presence of fungal hyphae (Figure 2 (Fig. 2)).
Clinical photograph on diffuse slit lamp illumination of the right eye (A) on day 7 of starting topical caspofungin; note the reduction in size of infiltrate with evidence of vascularisation suggesting healing; (B) on day 14, further reduction in ulcer size; (C) on day 28, note the evidence of scarring; (D) on cobalt blue illumination showing a residual epithelial defect of 3x2 mm.

Following the commencement of the treatment, healing of the corneal epithelium and resolution of the corneal infiltrate were observed from the periphery towards the centre with evidence of vascularisation, and the patient showed commendable clinical response (Figure 3 (Fig. 3)).

Although the patient initially had limbus to limbus corneal infiltrates, the scarring was less dense and involved superficial cornea with relative peripheral corneal sparing (Figure 4 (Fig. 4)).
