Details
Day Blindness also known as Achromatopsia, is characterized by cone photoreceptor dysfunction, causing severely reduced or complete vision loss during daylight hours. Dogs may also show signs of avoiding bright light or distress in bright light (photophobia). Age of onset is not yet clearly described but has been reported in puppies. However unlike other forms of Day Blindness observed in other breeds, the DB/RD mutation causes a more complete retinal degeneration in the Standard Poodle and affected dogs eventually lose both cone and rod cell function resulting in vision loss under all lighting conditions.
