Spontaneous Chronic Corneal Epithelial Defects

Spontaneous Chronic Corneal Epithelial Defects (SCCEDs) are a relatively common cause of canine corneal pathology. These lesions are frequently described as “indolent” or “Boxer” ulcers. SCCEDs likely arise as a result of corneal micro-trauma in association with pre-existing structural &/or physiological corneal abnormalities. Clinically, SCCEDs present as chronic superficial corneal ulcerations, typically surrounded by a visible rim of poorly adherent epithelial tissue, which is easily under-run by fluorescein creating a “halo” effect following corneal staining. Significant associated corneal inflammation, vascularization and/or granulation may develop in association with longstanding lesions. Discomfort is marked by blepharospasm and/or ocular discharge. Commonly affected breeds include the Boxer, Boston Terrier, French Bulldog & Labrador Retriever.
