The authors report a clinical case of poliethiological ulcerative mycotic keratitis in a horse. The disease was diagnosed in a 7-year-old mare, bay colour. In the inferior cranial quadrant of the right cornea ophthalmic examination revealed superficial and deep blood vessel ingrowth, oedema, multifocal dark brown subepithelial infiltrations as well as superficial corneal ulceration with detached epithelium. The impression cytology and mycological examination showed the presence of Aspergillus fumigatus as well as individual colonies of Aspergillus flavus in the examined research material. The horse was treated surgically and with the use of ophthalmic drops containing 0.2% fluconazole and 30% DMSO mixture. Oral fluconazole 500 mg was administered twice a day. The ophthalmic examination revealed the complete recovery of the corneal ulceration with a white scar 2 weeks after the operation. The pharmacological treatment was continued for 12 weeks. A control check-up a year after the treatment showed no blood vessels growing into the cornea, a marked reduction of the postoperative scar as well as higher corneal transparency at the ulcer site.
