Scleritis describes a primary inflammatory disorder of the canine scleral and/or episcleral tissues, which is thought to be immune-mediated in origin. Clinically this condition presents as an inflammatory infiltrate around part or all of the corneoscleral limbus, affecting one or both eyes. Associated discomfort may be manifested by blepharospasm &/or ocular discharge. Adjacent structures including the uveal tract may be involved & demonstrate clinical inflammation, extending in rare cases to necrotic scleral lesions, uveitis, retinal detachment and/or glaucoma. Commonly affected breeds include the Cocker Spaniel & Boston Terrier.
