Plain-English summary
A 1.5-year-old female Khaki Campbell duck was brought in because she was lethargic and had a swollen left eye. The vet found signs of eye problems, including discharge and redness, but initial treatments with antibiotics and anti-inflammatory medications didn’t help. After a few days, the eye condition worsened, and tests revealed a fungal infection caused by Aspergillus. The duck was treated with antifungal eye drops and later switched to oral medication. After about 84 days, her eye condition improved significantly, and there were no signs of the fungal infection.

Abstract
A 1.5-year-old, intact female khaki Campbell duck (Anas platyrhynchos domesticus) was evaluated for lethargy and a swollen left eye (OS). Mucoid discharge, chemosis, and conjunctival hyperemia with trace aqueous flare, indicating anterior uveitis, in the anterior chamber were evident on ophthalmic examination. There was no fluorescein stain uptake by the cornea. Initial topical antibiotic therapy and systemic anti-inflammatory treatments were unsuccessful, and the lesion progressed to a diffuse, yellow-white plaque, which covered 90%-95% of the cornea 4 days later. There was moderate blepharospasm, mild blepharedema, and epiphora OS. The mobility of the nictitating membrane was impaired because of the presence of the plaque over the cornea. Cytologic examination of a corneal scraping revealed fungal hyphae, and aerobic culture confirmed Aspergillus species. Treatment with topical voriconazole (1 drop OS q4h-q6h) was initiated and was switched to oral voriconazole (20 mg/kg PO q12h) 6 days after initiating treatment. The ocular disease improved during the antifungal treatment period. Eighty-four days after initial presentation (9 days after discontinuation of treatment), there was no clinical evidence of mycotic keratitis on ophthalmic examination.
