There are now thought to be at least two, maybe three, forms of PRA. The form that is showing up in the field lines is prcd-PRA though even with all the Carriers that have shown up since the DNA test became available and thus the numerous breedings that must have done in the past between Carrier x Carrier (and worse) with such a small number of dogs showing clinical signs (I believe we are up to 3 total), there is some question as to how serious of an issue this really is.
Regarding holding a clinic, I am certainly all for it. There are two ways this can be done. If you are looking for dogs who have clinical signs (this is especially important for pigmentary uveitis where early detection can make treatment much more successful and hopefully spare dogs great pain), there would need to be an opthalmologist physically doing exams because there is still not a DNA test for PU. While it would be wonderful for signs of PU to be detected in its early stage, we are still not able to distinguish which dogs are Carriers of the gene.
To answer your question about PU in the field lines, we are not seeing it. Supposedly there are 2 dogs from "field lines" that do have PU but names are not being discussed. I'm pretty sure I know who one of them is and have been told that he had/has Uveitis, not pigmentary, which is a totally different eye disease. From what I understand, his is suspected to be a result of a tick borne disease. And the other from field lines, well I'll believe it when I see it and who knows what the pedigree looks like and what is being called field lines.
If it is an Optigen clinic NORCAL is considering, blood could be drawn for the prcd-PRA test and/or the new DNA test for GR_PRA1, the cause of the majority of PRA in the Golden Retriever. This is also much more prevalent in the conformation lines.
Sorry to hijack folks, but I guess it's not an official hijack since we stayed on topic.
