To date there are no published reports of inherited ocular conditions in the French Bulldog. In addition, the numbers of individuals for which examinations are recorded are too low to identify the presence of significant ocular disorders. The French Bulldog is excluded for insufficient data. Examination are encouraged to accumulate information and reduce the likelihood of undetected conditions becoming problematic. Genetic Eye Disorders of the French Bulldog
Description and Comments 1. Distichiasis Eyelashes abnormally located in the eyelid margin which may cause ocular irritation. Distichiasis may occur at any time in the life of the dog. It is difficult to make a strong recommendation with regard to breeding dogs with this entity. The hereditary basis has not been established although it seems probable due to the high incidence in some breeds. Reducing the incidence is a logical goal. When diagnosed, distichiasis should be recorded: breeding discretion is advised. 2. Entropion A conformational defect resulting in an " in-rolling " of one or more of the eyelids which may cause ocular irritation. It is likely that entropion is influence by several genes (polygenic), defining the skin and other structures which make up the eyelids, the amount and weight of the skin covering the head and face, the orbital contents and the conformation of the skull. In the French Bulldog, entropion normally involves the lower eyelid and has been observed in the nasal half ( medial canthus region ). 3. Cataract Lens opacity which may effect one or both of the eyes and may involve the lens partially or completely. In cases where cataracts are complete and affect both eyes, blindness results. The prudent approach is to assume cataracts to be hereditary except in cases known to be associated with trauma, other causes of ocular inflammation, specific metabolic diseases, persistent pupillary membranes, persistent hyaloid or nutritional deficiencies. In the French Bulldog, this opacity has been observed origination in the equatorial and/or posterior cortical regions. The cataract formation is usually bilateral, occurs in young dogs ( 6 months to 2 years ), and rapidly progresses to completion. Posterior lenticonus has also been observed. References 1.

INSTITUTE FOR GENETIC DISEASE CONTROL IN ANIMALS PO BOX 222 Davis CA, 95617 916-756-6773 Please Note: This listing is only of the phenotypically unaffected dogs in the GDC registries. It includes all evaluations for each dog. This information is important in predicting the aging prognosis of a particular dog, but only of limited use in predicting the quality of one of its progeny. The main purpose of this listing is to encourage inquires leading to selection of dogs with know genotype. There may be additional information of a dog's relatives in the GDC registries. Please contact GDC for unaffected and affected ancestors, siblings and progeny of a selected dog. This quarterly report of unaffected evaluations is privileged information specifically for the exclusive use within your organization. GDC Listing from 01-01-1998 To 03-31-1998
