Abstract

An array of different retinal disorders is present as a threat in quite a
number of dog breeds. These often lead to profound visual impairment or
blindness. Many of the disorders are genetic, and they are, in Sweden as
well as in other countries, subject to breeding programmes.
The anatomy of the eye and the retina, as well as current examination
techniques (ophthalmoscopy, electroretinography (ERG) and genetic
analysis) are described. The more common retinal disorders encountered
in dogs in Sweden are discussed: retinal dysplasia, generalized
progressive retinal dystrophy, retinal pigment epithelial dystrophy, collie
eye anomaly, sudden acquired retinal degeneration, retinal detachment
and choroiditis. The possibly affected breeds are listed.
The value of diagnostic findings is discussed and current advances on the
subject in ophthalmologic research are accounted for.
