Comparison of Presumed Geographic Retinal Dysplasia Between a Cavalier King Charles Spaniel and a Labrador Retriever

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Geographic retinal dysplasia is inherited in the Cavalier King Charles Spaniel. This detailed multimodal imaging description of an affected dog demonstrates that the presumed dysplastic retina area consists of a thickened retinal nerve fiber layer, similar to plaque‐like lesions previously reported in other breeds, such as the Labrador ...
