Many diagnostic tests are available for concerned Aussie owners to check the overall health of a dog. Also, the Orthopedic Foundation for Animals (OFA) has an extensive database to track results and provide statistics for these concerns: hips, elbows, heart, patellar luxation (knees), and thyroid (autoimmune) disease. The OFA database also includes the results for eye exams performed by a Canine Eye Registration Foundation veterinarian, but only if the owner of the Aussie submits the results. This database is a great resource to investigate the lineage and related health of the progenitors of some dogs, at least regarding hip ratings.
