Disease description:
Congenital and inherited eye disorders are often breed related. Additionally, some ocular diseases have strong tendencies to affect certain breeds later in life.

Disease description in this species:
The alphabetized list of dog breeds below includes many of the commonly reported ocular disorders that are proven or presumed to be inherited. If an inheritance pattern is known and/or if a DNA test is available, the information is denoted after the disease. Detailed descriptions of each disease can be found in the related chapters.

Diagnosis
Diagnostic Tests: Complete ocular examination (with and without pupil dilation) is done to look for ocular abnormalities.

Clinical Signs
Vary depending on ocular disease.

Etiology:
Genetic, hereditary

Sex predilection:
None

Age predilection:
None

Diagnostic procedures:		Diagnostic results:
None

Treatment/Management/Prevention:
Veterinarians are encouraged to inform breeders of the value and availability of annual eye certification exams by board-certified veterinary ophthalmologists, especially prior to breeding. If an ocular disease is reported, the certifying organization (i.e. OFA in the United States, BVA/KC/ISDS Eye Scheme in the UK) will provide breeding advice based on the significance of the condition in regards to vision and/or its very strong evidence of heritability. Currently ten disorders receive an unequivocal recommendation against breeding in all breeds. These include glaucoma, KCS, cataract, lens luxation/subluxation, persistent hyperplastic primary vitreous (PHPV)/persistent hyperplastic tunica vasculosa lentis (PHTVL), retinal detachment, retinal degeneration (generalized progressive retinal atrophy, retinal dysplasia- geographic or detached forms, and optic nerve coloboma or hypoplasia. With increased awareness and screening examination, decreased incidence and/or elimination of hereditary eye diseases in purebred dogs may be possible. See the appropriate Associate chapters for sources of genetic tests.
