AOC C.O. cheat sheet

AOC-accredited orthoptic programs require a minimum of a bachelor's degree or equivalent and a structured clinical internship supervised by certified orthoptists.

Core didactic competencies include ocular anatomy, physiology, sensory and motor binocular vision, strabismus, amblyopia, neuro-ophthalmology, and diagnostic testing.

Clinical competency assessment uses direct observation and logbooks; students must demonstrate proficiency in cover testing, prism testing, retinoscopy, and ocular motility evaluation.

Accreditation standards require documented program outcomes, including graduation rates, certification examination pass rates, and employment placement.

Faculty qualifications: program directors must be certified orthoptists with a minimum of three years of clinical experience; medical directors must be ophthalmologists.

The AOC certifies orthoptists through a written examination, an oral/practical examination, and verification of clinical training; certification is distinct from state licensure.

Competency domains include patient communication, record keeping, ethical practice, and interprofessional collaboration with ophthalmologists and optometrists.

Minimum clinical hours for accredited programs are typically 1,000–2,000 hours of supervised direct patient care, including pediatric and adult populations.

Educational standards require training in calibration and maintenance of orthoptic equipment such as synoptophores, Hess screens, and prism bars.

AOC recertification typically requires a defined number of continuing education (CE) credits over a 3-year cycle, with a minimum number earned in orthoptics-related topics.

CE activities must be accredited by recognized bodies (e.g., AOC-approved providers, AMA PRA Category 1, or equivalent); self-study may have a credit cap.

Recertification may require documentation of clinical practice hours, professional activities, and adherence to a code of ethics.

A lapse in certification may require reinstatement fees, additional CE, and possibly re-examination, depending on the duration of lapse.

Some CE must be in core orthoptic domains (binocular vision, ocular motility, strabismus) to maintain clinical competence.

Record retention of CE certificates for at least one full recertification cycle is required for audit purposes.

Recertification standards emphasize patient safety, quality improvement, and evidence-based practice updates.

Failure to meet CE requirements by the deadline can result in suspension or revocation of certification until requirements are fulfilled.

Normal binocular single vision requires simultaneous stimulation of corresponding retinal points, intact fusion, and normal retinal correspondence.

Cover test: uncover test detects manifest (tropia); cover-uncover test detects latent (phoria). Prism bar or loose prism measures deviation magnitude in prism diopters (Δ).

Prism diopter (Δ) = 100 × tan(deviation angle in degrees); 1Δ deviates a ray 1 cm at 1 m.

Krimsky test estimates angle by placing prisms before the fixating eye until corneal light reflex is centered; useful in uncooperative or pediatric patients.

Hirschberg test: each 1 mm of corneal light reflex displacement ≈ 7° or ~15Δ of deviation; nasal displacement indicates exotropia, temporal indicates esotropia.

Amblyopia classification: strabismic, refractive (anisometropic or isoametropic), and deprivation; critical period for treatment is early childhood.

Stereopsis tests: Titmus (contour), Randot (contour), TNO (random dot), Frisby (real depth); normal stereoacuity is 40–60 arc seconds.

Worth 4-dot test assesses fusion and suppression: 2 red lights = left suppression; 3 green lights = right suppression; 5 lights = diplopia; 4 lights = normal fusion.

Hess/Lees screen charts record ocular motility deficits by comparing field plots; smaller square indicates underaction, larger indicates overaction.

Certified orthoptists practice under the supervision or in collaboration with an ophthalmologist, depending on state regulations and practice setting.

Scope includes diagnostic testing (visual acuity, refraction, binocular vision, ocular motility), patient education, and non-surgical management of binocular vision disorders.

Orthoptists may perform cycloplegic retinoscopy, administer eye drops under protocol, and assist in surgical planning; they do not perform intraocular surgery or prescribe medications independently.

Professional standards require informed consent, confidentiality (HIPAA), accurate documentation, and adherence to the AOC Code of Ethics.

Orthoptists must recognize limitations and refer patients with unexpected findings (e.g., papilledema, new-onset diplopia) to an ophthalmologist promptly.

Scope of practice varies by jurisdiction; orthoptists should know state laws governing delegation and supervision.

Continuing professional development and maintenance of certification are professional obligations to ensure competence.

Orthoptists serve as educators for students, patients, and other healthcare providers, and may engage in research within ethical guidelines.
