Abstract

Retinal degeneration in the Briard dog has been described by a number of authors in different countries. Congenital night blindness has been reported in the USA1 and in France2. In Sweden, the first Briards studied were congenitally night blind3, but in successive generations of dogs day vision also became affected4,5. In contrast, a slowly progressive central retinal degeneration has been reported in the United Kingdom6. These dogs had apparently normal vision initially with no evidence of night blindness, but severe visual impairment developed with time. The problem in the USA has been referred to as the Briard lipid retinopathy, the problem in France simply as congenital night blindness and the problem in Sweden as congenital night blindness with severely reduced day vision. The condition reported in the UK has been referred to as central progressive retinal atrophy (cPRA) or retinal pigment epithelial dystrophy (RPED).
