Fungal keratitis after nonpenetrating glaucoma surgery

Cornea. 2002 Jul;21(5):532-4. doi: 10.1097/00003226-200207000-00019.


Purpose: The purpose was to report a case of fungal keratitis that occurred following viscocanalostomy.

Methods: A 63-year-old man who underwent viscocanalostomy in his left eye presented with pain, redness, watering, and a decrease in visual acuity. Slit lamp examination showed teardrop-like stromal infiltration of the superior cornea. Corneal and conjunctival scrapings were obtained and a corneal biopsy was performed.

Results: Microscopic examination of smears demonstrated no bacteria and fungi. Corneal biopsy revealed dichotomously branching, septate hyphae suggestive of Aspergillus species. Culture identified no microorganism. The patient responded to amphotericin B treatment and the corneal infiltration resolved, leaving a plaquelike corneal scar.

Conclusion: Fungal keratitis may occur after viscocanalostomy, but prompt diagnosis and treatment can preserve the eye.
