Progressive retinal atrophy (PRA) in Irish Setters is an early onset inherited eye disease and can be due to more than a single mutation.   One form of PRA in Irish Setters is referred to as Rod-Cone Dysplasia Type 1 (PRA-RCD1) and occurs as a result of degeneration of both rod and cone cells of the retina which are important for vision in dim and bright light.  Symptoms can be recognized as early as a few weeks of age and progressive degeneration can continue for up to a year.  The first signs of the disease typically present around 1 month of age with vision loss in dim light also known as night blindness.  Dogs will typically show complete loss of night vision by about 5 months and difficulty with vision in bright light. Although there can be variation in disease progression, most dogs typically exhibit a rapid progression with total loss of sight by approximately 1 year of age.
