Aspectos clínicos da atrofia progressiva generalizada da retina em cães

Abstract

Hereditary retinal diseases affect both humans and animals. Generalized progressive retinal atrophy (APGR) is a prolonged and progressive retinal degeneration due to inherited autosomal recessive mutations in genes expressed in photoreceptors and in the retinal pigment epithelium. Clinically, bilateral mydriasis, night blindness, decreased or absent pupillary reflex are observed. The diagnosis is based on clinical history, ophthalmological examination, ultrasound and electroretinography as complementary tests. For these facts, the science of this pathology is important for its identification, in order to avoid its multiplication.
