Details
As detailed by Kijas et al. (2002), vision is normal for the first few months, but by 12-18 months, vision loss is spreading slowly with particular problems for the dog moving between different light levels. Homozygotes (two copies of the abnormal gene) have more severe clinical signs than heterozygotes (one copy of the abnormal gene).

From Kijas et al. (2002), rod vision is normal for at least the first few months. But by 12-18 months, degeneration is evident, spreading slowly from a disease focus in one retinal region. In addition, there is an abnormally slow recovery of rod photoreceptor function after exposure to light. Homozygotes have more severe clinical signs than heterozygotes.
