Corneal Dystrophy and the Cavalier King Charles Spaniel
The form of corneal dystrophy most common among CKCSs is epithelial/stromal dystrophy, which describe the gray-white opacity which is visible in the dog's eyes. All CKCSs should be examined at least annually by a board certified veterinary ophthalmologist. They are listed on this webpage of the website of the American College of Veterinary Ophthalmologists (ACVO): www.acvo.org/locate.htm Treatment Corneal dystrophy usually does not affect vision, is not painful, and no treatment is necessary. Breeders' Responsibilities Currently, the Canine Eye Registration Foundation (C.E.R.F.) does not deny certification to Cavalier King Charles Spaniels which are affected with corneal dystrophy, because the Genetics Committee of the ACVO classifies the disorder as a "breeder option" for CKCSs. However, the Canine Inherited Disorders Database recommends that all dogs suffering from corneal dystrophy not be bred.
