OFA (CERF) Examinations

What is a Genetic Disease?

Genetic diseases are those that are passed on from parent to offspring through genes that carry the codes for each specific trait. Many of the diseases and disorders that affect the eyes are associated with specific genetic factors and multiple eye diseases which affect dogs are known to exhibit evidence of a genetic or heritable cause. The Top 10 Genetic Diseases according to the American College of Veterinary Ophthalmologists (ACVO) are listed below.

  1. Keratoconjunctivitis sicca (KCS)
  2. Cataract
  3. Lens luxation or subluxation
  4. Glaucoma
  5. Persistent hyperplastic primary vitreous (PHPV)
  6. Retinal detachment
  7. Retinal dysplasia – geographic or detached forms
  8. Optic nerve coloboma
  9. Optic nerve hypoplasia
  10. Progressive Retinal Atrophy (PRA)

Veterinary Eye institute Provides OFA Eye Certification Exams

OFA Eye Certification (previously “CERF” exams) are screening examinations performed by board certified veterinary ophthalmologists to identify changes within the eye(s) suggesting the presence of one or more of these diseases. The exam is performed following pupillary dilation and consists of indirect ophthalmoscopy & slit lamp bio microscopy.

After the examination, the ophthalmologist will complete the OFA Companion Animal Eye Registry (CAER) form and indicate any specific disease(s) found. The forms are in triplicate – one copy is for the vet’s records, one is for the owner, and one is for the OFA’s Clinical Database. Certification is valid for 12 months from the date of the eye exam. Annual re-examination is recommended.

To schedule an OFA examination for one or more pets, please call your nearest VEI.
