ACVO Veterinary Ophthalmology study guide
ACVO Veterinary Ophthalmology · Work through your exam, one topic at a time.
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. The ACVO Veterinary Ophthalmology study guide has 4 sections and about 1,155 words.
01General Veterinary Ophthalmology: Examination, Anatomy, and Clinical Reasoning
A candidate must be able to describe the ophthalmic exam in order and justify each step: menace response (central/cortical, learned, not a pupil test), dazzle and pupillary light reflexes (afferent vs efferent limb), palpebral reflex (CN V and VII), vestibulo-ocular and oculocephalic responses, and vision testing by obstacle course. Know the neuro-ophthalmic pathways well enough to localize a lesion: a blind eye with a fixed, dilated pupil points to the retina or optic nerve (afferent), whereas a normal pupil with absent menace suggests central disease.

Understand drug delivery and barriers: corneal epithelium is lipophilic, stroma hydrophilic, so topical drugs need balanced solubility; the blood-aqueous and blood-retinal barriers limit systemic drug penetration. Know the classes: mydriatics/cycloplegics (atropine, tropicamide, phenylephrine - sympathomimetic vs parasympatholytic), miotics (pilocarpine), topical antibiotics and their spectrum, antifungals (natamycin, itraconazole), antivirals (for feline herpesvirus), corticosteroids vs NSAIDs (and the risk of corticosteroid use with corneal ulceration), and glaucoma drugs (prostaglandin analogs, carbonic anhydrase inhibitors, beta-blockers, osmotic agents).

Build a differential framework by compartment. Adnexal: entropion, ectropion, distichiasis, trichiasis, prolapsed gland of the third eyelid (cherry eye).

The CAER (Companion Animal Eye Registry) examination is a standardized screening performed by a board-certified ophthalmologist to identify inherited ocular disease, inform breeding decisions, and provide a permanent record. Know the process: owner and dog identification, history, complete ophthalmic exam (often with pharmacologic dilation), and a standardized form documenting normal findings or specific diagnoses.
