There are four stages of pinkeye, with clinical signs ranging from conjunctivitis, excessive tearing, photosensitivity, ocular pain, squinting of the eyelid, corneal edema, and corneal ulceration to corneal rupture and blindness.

The most common manifestation of IKC in cattle is infectious bovine keratoconjunctivitis (IBK; bovine pinkeye), for which the initial key clinical sign is central corneal ulceration. Microbiological, cytological, and/or molecular testing of samples collected from affected eyes can help identify specific organisms associated with IKC or IBK.

2023年12月15日 · Artificial intelligence (AI) was developed to distinguish cattle by their muzzle patterns and identify early cases of disease, including infectious bovine keratoconjunctivitis (IBK). It was tested on 870 cattle in four locations, with 170 developing IBK.

Infectious bovine keratoconjunctivitis (IBK), also known as pink eye complex and infectious ophthalmia, is characterized by blepharospasm, conjunctivitis, lacrimation, and varying degrees of corneal opacity and ulceration.

Generally unilateral, runs its course with blepharospasm, epiphora, conjunctivitis, photophobia, corneal infection and ulceration. In addition to the ocular lesion itself, IBK implies a diminution of milk production and of the conversion rate and growth of fattening calves. LESIONS:

2024年8月2日 · Infectious bovine keratoconjunctivitis (IBK) or pinkeye can be very problematic at times in cattle herds. It is manifested as an inflammation/infection of the cornea and conjunctiva of one or both eyes in affected cattle.

This article suggests the term pinkeye should no longer be used, offers a case definition for IBK (a herd disease), and suggests describing ocular signs of IBK using existing clinical descriptors rather than resorting to novel scores. A new term “ocular moraxellosis” is defined as IBK from which Moraxella spp are demonstrated.

Pink eye in cattle is also called Infectious Bovine Keratoconjunctivitis (IBK) of ruminants and Infectious ophthalmia. It is characterized by blepharospasm, conjunctivitis, lacrimation, and varying corneal opacity and ulceration.
