Congenital stationary night blindness (CSNB)

LABOKLIN Service ID: 8011

The Briard suffers from a retinal disorder characterized by congenital night blindness with various degrees of visual impairment under photo topic illumination. The vision of affected dogs can range from normal day vision to profound day blindness. The disease generally appears first in early whelpage, at about six month and results from a mutation in the RPE65 gene. Along with the visual impairment, affected dogs have abnormal electroretinograms (ERG).
