Eosinophillic Keratoconjunctivitis (EKC)

Eosinophillic keratoconjunctivitis (EKC) describes a feline condition comprising infiltration of the corneal and/or conjunctival tissues with an eosinophil-rich inflammatory infiltrate. Clinically, affected cats display a variable degree of cream to white-colored infiltration & “plaque-like” deposition, frequently in association with vascular keratitis. Changes typically originate from the corneoscleral limbus and may be uni or bilateral. Associated discomfort may be manifested by blepharospasm &/or ocular discharge.
