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.

Sept. 2015: To date neither Trevor nor any of the other 5 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.

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.
