Fungal keratitis associated with vernal keratoconjunctivitis.

PURPOSE: To report a case of fungal keratitis associated with vernal keratoconjunctivitis.

CASE REPORT: A 22-year-old man with a history of vernal keratoconjunctivitis since October 1999 developed a shield ulcer in the left eye in June 2000, which resolved with intensive topical steroid therapy. He presented in August 2001 with onset of acute pain, redness, and decreased vision. The tarsal conjunctiva in the left eye showed large papillae. The cornea showed a white plaque-like lesion with an underlying stromal infiltrate involving the upper half of the cornea. The overlying epithelial defect measured 4.5 x 2.5 mm. The anterior chamber showed 1+ flare and cells and hypopyon measuring about 1 mm.

RESULTS: Corneal scrapings were performed for microbiologic investigations. Smears of corneal scrapings revealed septate fungal filaments, and the culture showed a significant growth of Aspergillus flavus.

CONCLUSIONS: Fungal keratitis may be associated with vernal keratoconjunctivitis. Though rare, fungal keratitis should be considered in the differential diagnosis of infections associated with vernal keratoconjunctivitis.
