Orthoptist Job Description

An orthoptist is the clinician an eye department hands a crossed, drifting or double-seeing patient to before anyone books an operating room. The work is about binocular vision: how two eyes aim, move together and fuse two images into one. ONET, the Labor Department's occupational database, sums up the job as evaluating, diagnosing or treating disorders of the visual system "with an emphasis on binocular vision or abnormal eye movements." ONET's sample of reported job titles for the role includes Clinical Orthoptist (CO) and CO (Certified Orthoptist).

The caseload has two halves. The pediatric half brings infants with esotropia, preschoolers referred after a failed vision screening, and school-age children whose intermittent exotropia shows up at the end of a long day. The adult half brings double vision from a sixth nerve palsy, restrictive strabismus from thyroid eye disease, childhood strabismus that has decompensated in middle age, and misalignment after a stroke or an orbital floor fracture. The measurement kit is the same for both groups. The conversation in the room is not.

A new-patient workup follows a set order. Visual acuity comes first, using a method matched to age, from preferential looking cards for babies to letter charts for adults. Then the cover tests: a unilateral cover test to find a manifest deviation, and an alternate prism cover test to size it in prism diopters at distance and near and across the gaze positions. Ductions and versions show whether a muscle is weak or tethered. Sensory testing with the Worth 4-dot, a Randot stereotest or Bagolini lenses tells the physician whether the patient fuses, suppresses or sees double. In clinics that keep one, a synoptophore adds a finer read on fusion range and torsion.

Treatment is the nonsurgical side of strabismus and amblyopia care. O*NET's task list names the tools: corrective lenses, patches, drops, fusion exercises and stereograms. In practice that means building a patching or atropine penalization plan for an amblyopic child, trialing a Fresnel prism on an adult with diplopia, assigning convergence exercises, and checking at each visit whether the plan is working. When a deviation needs surgery, the orthoptist's measurements are the numbers the strabismus surgeon plans from, and the post-operative measurements show whether the result held.

The job reaches past the exam lane. O*NET also lists training students, residents and other health professionals, taking part in clinical research, presenting or publishing papers, assisting with procedures such as fundus photography and tonometry, and screening children's vision in schools or community health centers. Vanderbilt Eye Institute describes orthoptists as physician extenders who work primarily with pediatric ophthalmologists. Mayo Clinic's career guide lists the places they practice: ophthalmology clinics, hospitals, academic medical centers, pediatric ophthalmology practices, vision care specialty clinics, eye surgery centers and research institutions.

The route into orthoptics has few steps and a lot of clinical hours. It starts with a bachelor's degree, which the American Association of Certified Orthoptists (AACO) lists as the entry requirement for an orthoptic program. According to AACO, the certifying body mandates no specific prerequisite courses, individual programs may set their own, and the Graduate Record Examination is not required. As a rough guide, coursework in biology, health science or psychology and some shadowing time in a pediatric eye clinic make an application easier to read.

Training lasts 24 months in a program accredited by the American Orthoptic Council (AOC), the body that certifies orthoptists and accredits their programs. AACO describes each program as a mix of didactic courses, taught online and in person by certified orthoptists, and clinical training with patients of all ages under the supervision of a certified orthoptist or an ophthalmologist. Seats are scarce: AACO notes that many programs accept only one student per year, and Vanderbilt Eye Institute is accredited for two orthoptic students per year. Vanderbilt's program includes 200 hours of didactic learning plus rotations in its pediatric ophthalmology and neuro-ophthalmology clinics. Duke's orthoptic fellowship promises at least 1,200 patient encounters. Mayo Clinic School of Health Sciences runs a 24-month AOC-accredited program in Rochester, Minnesota.

Ophthalmic technicians have a shorter path. AACO says advanced standing may be awarded to ophthalmic personnel who hold an undergraduate degree and a current Certified Ophthalmic Technician (COT) or Certified Ophthalmic Medical Technologist (COMT) credential, both awarded by IJCAHPO. Advanced standing students must still complete a minimum of 12 months in an accredited program, and the program director sets the exact length of training based on each student's progress.

After 24 months of training, and on the recommendation of the supervising orthoptists, students become eligible for the AOC certifying examinations. The AOC's continuing education guidelines describe them as written and oral/practical certifying examinations, built on the council's syllabus of orthoptic instruction and its core competency document. Passing earns the Certified Orthoptist (CO) credential. O*NET's survey of the occupation found that 67% of respondents said a new hire needs a post-baccalaureate certificate.

Typical guidance on the skills that separate a strong orthoptist:

• Measurement discipline: repeatable prism cover results, careful neutralization, and honest notes when a toddler would not cooperate.
• Pediatric technique: getting a fixation target held by a two-year-old for long enough to measure.
• Clinical reasoning: telling a restrictive pattern from a paretic one and knowing when to flag a new palsy for urgent review.
• Family coaching: explaining why patching matters and building a plan a busy household will actually follow.
• Teamwork: working within a physician-led clinic and teaching residents who rotate through.

Start with pay, because the data need explaining. BLS does not publish a wage series for orthoptists. O*NET places them in a residual occupation, Healthcare Diagnosing or Treating Practitioners, All Other (SOC 29-1299), whose national median wage was $115,210 in May 2025. That national figure is weighted toward federal employment: the BLS industry tables count 18,810 of the occupation's 28,630 jobs in the federal executive branch. This page therefore shows the same occupation's row for general medical and surgical hospitals as context only: the group also covers practitioner jobs unrelated to orthoptics, so neither figure is orthoptist pay. Hospitals are among the workplaces Mayo Clinic's career guide lists for orthoptists.

O*NET's 2025-2035 projection for that broader occupation is faster than average growth, 5% to 6%, with about 1,900 openings a year on average and 39,600 workers in 2025. Those figures describe the whole residual group, not orthoptists alone. BLS does not report orthoptist employment separately.

The demand picture comes from the physicians orthoptists work beside. A 2025 study in the Journal of Pediatric Ophthalmology & Strabismus found the pediatric ophthalmology and strabismus fellowship match rate lower than other subspecialties every year from 2016 to 2024, while fellowship spots grew 10.2%, significantly less than the increases in retina and glaucoma. U.S. membership in the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) held steady while international membership grew 47.1% since 2016. Its authors concluded that as experienced pediatric ophthalmologists retire and interest remains lower, "the provider gap widens and decreases accessibility to pediatric eye care." A separate 2025 Journal of AAPOS study, a structured telephone survey of 925 offices, found a successful appointment rate of 39.7% with ophthalmologists against 65.6% with optometrists, with average waits for successful appointments of 52.8 days at ophthalmologists' offices and 25.4 days at optometrists'. Neither study counts orthoptists. Both describe the pediatric eye care capacity that orthoptists work inside.

Digital amblyopia therapy is now part of the treatment menu. EyeNet, the American Academy of Ophthalmology's magazine, in June 2025 summarized a cost-utility study of two binocular digital amblyopia treatments, Luminopia and CureSight. In that analysis, 12 weeks of Luminopia cost $1,951, against $514 for glasses alone and $652 for 16 weeks of atropine; the authors judged the digital therapies relatively cost-effective. For an orthoptist, each new option is one more regimen to choose between, explain to parents and follow with acuity and stereoacuity checks.

Mayo Clinic's guide says orthoptists can advance to leadership and supervisory roles or move into research or teaching in academic settings. The University of California's class specifications separate the Senior Orthoptist from the Orthoptist: the senior role plans and coordinates the daily operations of an orthoptic clinic, supervises an orthoptist and trains students. Mayo also names specialty paths such as neuro-ophthalmology, low vision, genetic disorders and pediatric eye care. Directing an accredited training program, coordinating clinical trials in pediatric eye research and supervising resident teaching are other directions within academic departments. Broader ophthalmic testing skills, such as visual fields and retinal imaging, add to the clinic roles an orthoptist can cover.

Dear Dr. Ramirez,

I am applying for the Orthoptist position in the Division of Pediatric Ophthalmology and Strabismus at Lakeview Children's Hospital. I completed my orthoptic fellowship at a university eye institute this June, passed the American Orthoptic Council board examinations in the summer, and hold the CO credential. I want to work in a clinic that sees both complex pediatric strabismus and adult diplopia, and Lakeview's combined pediatric and neuro-ophthalmology service fits that goal.

During training I ran full motility workups on infants, school-age children and adults. I am comfortable with alternate prism cover testing at distance and near, nine-position measurements for incomitant deviations, and sensory testing with the Worth 4-dot, Randot and Bagolini lenses. My supervising orthoptist trusted my pre-operative measurements for surgical planning by the second year, and I learned to repeat a measurement rather than guess when a toddler lost fixation.

Much of my clinic time went to amblyopia. I built patching and atropine plans with families, wrote simple home logs that parents could fill in on a phone, and called families between visits when compliance slipped. Several children who had stalled on patching improved once we changed the schedule to fit their school day, and I enjoy that problem-solving side of the work.

On the adult side, I trialed Fresnel prisms for patients with sixth nerve palsies and thyroid eye disease and tracked them until the deviation stabilized and the surgeon could decide on next steps. I also taught first-year residents the cover test sequence during their rotation and presented a case of Brown syndrome at our department grand rounds.

I would welcome the chance to discuss how I could support your surgeons and families. Thank you for your time and consideration.

Sincerely, Jordan Ellis, CO
