Progressive Retinal Atrophy Resource Center

In October 2008, when he was almost 2 years old, Trevor was given a routine Optigen screening for PRA. PRA (progressive retinal atrophy) is a genetically transmitted disease that leads to blindness. Even though PRA is extremely rare in Golden Retrievers, Trevor was found to be "affected" with prcd-PRA.

From the Optigen website:

PRA refers to a group of diseases that cause the retina of the eye to degenerate slowly over time. The result is declining vision and eventual blindness. “prcd” stands for “progressive rod-cone degeneration” which is the type of PRA known in several breeds.

Jan. 2016: To date neither Trevor nor any of the other 4 prcd-PRA-affected Goldens I personally know have shown any symptoms, nor has any evidence of retinal degeneration been detectable in their annual eye exams. Trevor recently finished his PACH3 agility title, and he is now training for his JH. He shows no signs of compromised eyesight at age 9.

General Information


Golden Retriever Genetic Databases

  • Golden Retriever DNA Database -- Records the results of DNA testing performed on individual Golden Retrievers. Lists prcd-PRA status for dogs whose owners have submitted their data.
  • -- Pedigrees and health information submitted by GR owners. Some owners have included prcd-PRA status in the "Honorifics" field, but there is also now a "PRA status" field.
