Hair from the lesions is predominantly responsible for the associated irritation resulting in chronic inflammation of the conjunctivae and cornea and may cause visual impairment. Ocular dermoids are rare in cattle, with the prevalence estimated between 0.002% and 0. 4%.Case: A one-day-old Simmental calf presented for bilateral haired masses on the eyes and tumor-like growth since birth. The calf was admitted to the University of Adnan Menderes, Faculty of Veterinary Medicine 1 days after initial examination. The calf weighed 35 kg, was in good bodily condition and no further abnormalities were detected on physical examination, complete blood count and serum chemistries. General anesthesia was induced and maintained with an intravenous detomidine-ketamine-midazolam combination. The corneal dermoids extended slightly beyond the inferonasal limbus and then merged with a second mass of lightly haired tissue within the inferonasal bulbar conjunctiva of both eyes. The dermoids were excised by superficial lamellar keratectomy that was extended into the inferonasal conjunctiva. The nasal masses were excised by electrocautery. All excised tissue was submitt
