PLEASE NOTE THAT THIS TEST REQUIRES A BLOOD (EDTA) SAMPLE TO BE SUBMITTED. This is another form of PRA found in the breed - Type B (HIVEP3). PRA-affected dogs typically show a similar sequence of clinical abnormalities in the course of the disease: night blindness followed by progressive loss of day vision and eventual blindness under all light conditions. Routine eye exams reveal the progressive thinning due to degeneration or “atrophy” of the retina, hence the name given to the disease.
Ophthalmologic - Associated with the eyes and associated structures
