Chronic superficial keratitis (CSK)—also known as German shepherd pannus, Überreiter’s syndrome, or degenerative pannus—is a progressive, usually bilateral, and potentially vision-threatening disease of the canine cornea.¹,² It is characterized by chronic inflammation of the corneal epithelium and anterior stroma, which results in neovascularization, pigmentation, and opacification.¹ Atypical pannus (ie, plasmoma), an inflammatory process of the nictitating membrane, has also been described.²
Clinical History & Signalment
Large breeds—in particular German shepherd dogs, shepherd crossbreeds, border collies, and greyhounds—are predominantly affected; however, CSK can occur in dogs of any size and breed.² Age of onset is an important prognostic indicator. The condition typically progresses rapidly in young dogs (ie, 1-5 years of age); lesions may be less severe in animals affected later in life (ie, >4-5 years of age).²
