ExploreAbout this exam
The American College of Veterinary Ophthalmologists (ACVO) is a Recognized Veterinary Specialty Organization of the AVMA that promotes excellence in veterinary ophthalmology through advanced training, certification, research, and education. Certification itself is administered through the American Board of Veterinary Ophthalmology (ABVO), and only board-certified veterinary ophthalmologists credentialed through ABVO are ACVO Diplomates. This independent study material is intended for veterinarians preparing for specialty-level assessment in veterinary ophthalmology, whether for board credentialing or for advanced practice competence. It is not an official ACVO or ABVO product and is not affiliated with either organization. Content is organized around four domains: general veterinary ophthalmology; ocular pharmacology and toxicology; common ocular conditions; and canine eye disease screening and genetics, including the ACVO Companion Animal Eye Registry (CAER) program administered in collaboration with the Orthopedic Foundation for Animals (OFA), which publishes annual breeding recommendations with the ACVO Genetics Committee in the ACVO Blue Book. Because the source material does not publish an examination blueprint, item count, time limit, passing standard, fee, retake policy, or validity period, this guide makes no claims about those parameters; candidates should confirm all logistics directly with the certifying body. Preparation should combine systematic review of ocular anatomy, pathology, and therapeutics with case-based reasoning and familiarity with screening and genetics concepts.
What you'll study
About ACVO Veterinary Ophthalmology preparation
Who actually administers the veterinary ophthalmology board certification?
Certification is administered through the American Board of Veterinary Ophthalmology (ABVO). The ACVO is the specialty college; only board-certified veterinary ophthalmologists credentialed through ABVO are ACVO Diplomates. Contact ABVO directly for credentialing requirements, application materials, and examination logistics rather than relying on third-party summaries.
What does the exam cover?
Expect specialty-level material across general veterinary ophthalmology, ocular pharmacology and toxicology, common ocular conditions, and canine eye disease screening and genetics. The genetics portion includes the ACVO CAER screening program, run with the Orthopedic Foundation for Animals, and annual breeding recommendations published in the ACVO Blue Book.
How long is the exam and how many questions are there?
That information is not published in the source material reviewed, so no figure is given here. Item counts and time limits are set by the certifying body and can change between cycles. Confirm current specifications with ABVO before you build a timed practice plan around any number.
What score do I need to pass, and how much does it cost?
Neither the passing standard nor the fee is stated in the source material reviewed, so this guide does not report a value. Both are set by the certifying organization and are subject to revision. Verify the current passing standard and fee schedule directly with ABVO before applying.
If I fail, how soon can I retake it?
The retake policy is not specified in the source material reviewed, so no timeline is given. Retake rules typically depend on whether you are a first-time or repeat candidate and on the cycle calendar. Ask ABVO for the current policy in writing before you plan a repeat attempt.
How long is a passing result valid?
Validity periods are not stated in the source material reviewed, so this guide does not assert one. Certification maintenance and any re-verification requirements are governed by the certifying body. Confirm current requirements with ABVO, since maintenance-of-certification rules are revised periodically.
In what order should I study the four domains?
Build general ophthalmology first, since pharmacology and disease recognition both depend on anatomy, physiology, and pathology. Layer pharmacology and toxicology next, then work through common ocular conditions as applied cases. Finish with screening and genetics, which is largely programmatic and benefits from a settled clinical foundation.
What are the most common failure modes?
Weak applied reasoning rather than weak recall: candidates memorize drug lists without linking them to species-specific risk, or recognize a lesion but cannot justify a diagnostic or therapeutic plan. A second frequent gap is the screening and genetics material, which candidates skip because it feels administrative rather than clinical.
Why is feline topical steroid use emphasized in pharmacology study?
Cats presenting with squinting, discharge, redness, or corneal cloudiness often have feline herpesvirus-1 as the underlying cause of surface ocular disease. Steroid selection in that setting carries risk, which is why the ACVO publishes client-facing guidance on why cats should not receive topical steroid eye medication. Expect species-specific therapeutic reasoning.
Where can I find the ACVO CAER screening details relevant to genetics questions?
The ACVO collaborates with the Orthopedic Foundation for Animals to administer CAER examinations, and breeders are directed to the OFA website for program questions. Study the purpose of screening, how results inform breeding decisions, and the Blue Book breeding recommendations rather than memorizing administrative forms.
