A 40-year-old female presented with pain, redness, watering, and foreign body sensation for three days duration. Visual acuity was 20/120 with diffuse conjunctival congestion and multifocal fine-to-coarse, stuck-on epithelial lesions [Figure 1]a. Careful corneal scrapping on KOH mount revealed a “Microsporidial Bowl” with central microsporidial spores (black arrow) surrounded by epithelial cells [Figure 1]b. These lesions fluoresced bluish-white on combined KOH and Calcofluor stain [Figure 1]c. Classical clinical picture, easy diagnosis with Calcofluor staining and timely treatment with topical moxifloxacin with voriconazole led to complete resolution of lesions in 14 days with restoration of visual acuity to 20/20.[1],[2]
