Abstract:

Case history: A nine-month-old Hereford-Friesian heifer presented with exophthalmos and phthisis bulbi of the right eye.

Clinical findings: This was the only calf in the mob with severe clinical signs but there was an additional calf in the mob with early signs of eye disease consistent with a diagnosis of infectious bovine keratoconjunctivitis (IBK). The contralateral eye of the affected calf also showed early signs consistent with IBK.

Diagnosis: A collapsed exophthalmic globe, most likely secondary to a perforating corneal ulcer caused by IBK, colloquially known as “pink eye”.

Clinical relevance: Farmers and veterinarians should be aware of the predisposing factors for IBK and the early clinical signs so that intervention can be instigated before exenteration is required and the animal’s welfare is compromised.
