The American College of Veterinary Ophthalmologists® (ACVO®) is an organization, not an actual physical location, that (through the American Board of Veterinary Ophthalmology® or ABVO®) has established certifying criteria for Diplomates of the American College of Veterinary Ophthalmologists (DACVO®) and residents in training to become Diplomates.

To become a DACVO, a person must first graduate from veterinary school, attain a minimum of 12 months full-time clinical practice as a veterinarian, and complete a 3-year or longer residency training program in veterinary ophthalmology.  The applicant then is permitted to take the ABVO certifying examination. The exam is a multi-day process consisting of multiple written and practical components. After achieving all of these criteria, a veterinarian is recognized as a "Diplomate of the American College of Veterinary Ophthalmologists" and is board-certified in veterinary ophthalmology. In the United States, no-one may use this title unless they have successfully completed all of these steps. 


The purpose of the ACVO is to advance ophthalmology in all phases of veterinary medicine. 


  • provide an organizational structure to facilitate efficient exchange of ideas of interest to specialists in veterinary and comparative ophthalmology,
  • encourage education, training, and research in veterinary ophthalmology,
  • establish standards of training and experience in this field and to recognize individuals who have fulfilled such standards.

Credentials Verification - "Is my veterinarian board certified?"

You may wish to check our list of Active ACVO Member Diplomates to verify that your veterinarian is indeed a board certified specialist. In most cases if the veterinarian is not listed on our site, they are not ophthalmologists, specialists or board certified. If they are not listed in this referral area but state that they are a boarded ophthalmologist, there is a chance they could be boarded but are not ACVO members in good standing. Check this comprehensive list of boarded Diplomates to be certain. You may contact the ACVO office if you are unsure or would like clarification.

If you suspect someone is promoting themselves as "board certified", a "specialist in veterinary ophthalmology", an "ophthalmologist" or "Diplomate" of this College, and they do not appear to be board certified by the ACVO, please contact our office with this information. This practice may be in violation of the American Veterinary Medical Association, the American Board of Veterinary Specialists and/or the ACVO's Code of Ethics.

Credentialing outside of the United States

There are several colleges and/or societies around the world that certify veterinarians in their country. If you would like to locate a veterinary ophthalmologist outside of the U.S. this list of organizations may be a good place to start.
