Together with the Genetics Committee of the ACVO, the OFA has recently completed the 7th Edition of “Ocular Disorders Presumed to be Inherited in Purebred Dogs,” commonly known as the Blue Book. The 7th Edition contains statistics through the end of 2014. The statistics represent all exam forms sent in by examining ACVO Ophthalmologists, regardless of whether the owners submitted the results for official certification. The statistics are grouped by years: 1991 – 1999, 2000 – 2009, 2010 – 2013, and the last year 2014 displayed by itself. The statistics prior to 2012 represent data previously collected by CERF. 

The text portion for each breed contains the breed specific Breeder Option or Ineligible for Certification conditions. These are in addition to those conditions which are considered Ineligible for all breeds including: Glaucoma, Keratoconjunctivitis Sicca, certain Cataracts, Len Luxation/Subluxation, PHPV/PHTV, Retinal Detachment, Retinal Atrophy, Retinal Dysplasia, Optic Nerve Coloboma, and Optic Nerve Hypoplasia. These pages represent the breed specific recommendations of the ACVO and are used by the OFA (and previously CERF) when issuing reports. 

Since implementing the eye registry at the end of 2012, the OFA has processed over 65,000 eye certifications, and an additional 50,000+ exam forms for the statistics. And in keeping with our non-profit mission “To improve the health and well-being of companion animals through a reduction in the incidence of genetic disease,” the OFA donates a portion of all eye registry revenues to the ACVO Vision for Animals Foundation (ACVO VFAF) that provides funding for grants in support of research into the elimination of ocular diseases causing vision loss and suffering in animals. In the last two and half years the quarterly donations to the ACVO VFAF have totaled nearly $70,000, so every OFA Eye Certification has a positive impact on canine health research!
