This Dachshund, who assisted scientists from the Norwegian School of Veterinary Science, MIT and Harvard with their research, is wearing specially designed sunglasses to help with his day blindness, which is caused by inherited cone-rod dystrophy (CRD).

In a study published online in Genome Research (www.genome.org), researchers identified a novel mutation in a gene associated with CRD in dogs, raising hopes that potential therapies can be developed for people suffering from these eye disorders.
