# US Pediatric Ophthalmology Workforce Strain and the Geographic Access Cliff

## Headline findings

The cleanest read of the current U.S. picture is this: depending on how one counts, the country appears to have roughly **1,056 pediatric ophthalmologists listed in public directories in March 2022** and **1,060 listed in April 2023**, but recent reviews argue that only **about 800 to 900** may be actively providing surgical pediatric ophthalmology care. Using the 2022 directory-based count, the U.S. had **12.7 pediatric ophthalmologists per 1 million people younger than 19 years**. Meanwhile, **90.0% to 90.2% of U.S. counties had none**, and a newer coverage analysis found **about 1 in 7 American children live more than 60 minutes from pediatric ophthalmology care**. The pipeline is weak: across fellowship cycles from 2016 to 2024, pediatric ophthalmology and strabismus fellowships had an **average vacancy rate of 29.8%**, and the share of available positions filled by U.S. graduates fell from **72% in 2016 to 47% in 2024**. citeturn14search11turn14search3turn30search17turn21search2turn11search1turn11search4turn15search2

The economic signal points the same way. A 2022 survey of 243 pediatric ophthalmologists found widespread revenue compression and rising overhead, while a 2023 Medicaid-focused study found that academic eye centers and children’s hospitals had **mean wait times of 3.9 months for a new patient visit**, **3.4 months for follow-up**, and **2.7 months for non-emergency surgery**, with longer new-patient waits in more Medicaid-heavy states. In another survey, **6.5% of respondents reported retiring in the prior 3 years**, and **37.8% said they would not recommend pediatric ophthalmology fellowship to a resident**. citeturn28search3turn30search7turn24search5

The orthoptics case is not that orthoptists replace pediatric ophthalmologists. It is that the U.S. is trying to solve a subspecialty access problem with too little delegated binocular-vision, ocular-motility, and diagnostic capacity. The U.S. currently has only **17 AOC-accredited orthoptic training programs**, a tiny and poorly measured workforce, and even federal occupational data do not cleanly identify orthoptists because O*NET maps them to a much broader residual occupation. Yet the evidence that orthoptists can extend capacity is consistent: a U.S. practice-efficiency study found that adding a certified orthoptist increased revenue by **more than $70,000** over 6 months, and orthoptist-led models abroad have shown shorter visits, improved throughput, lower per-appointment cost, and lower waiting lists. citeturn33view0turn32search6turn35search3turn36search2turn36search20turn36search1

## Supply and pipeline

The U.S. pediatric ophthalmology workforce is strained in two different ways at once: the **current stock is too thin and too unevenly distributed**, and the **future inflow is weak**. The best recent directory-based counts identified **1,056 pediatric ophthalmologists in March 2022** and **1,060 in April 2023**, which is basically flat growth. A newer review then argued that the number of clinicians actually providing surgical pediatric ophthalmology care may be closer to **800 to 900**, which is a materially smaller workforce than the public-directory count suggests. That disagreement is not just academic. It means the U.S. lacks a clean, registry-grade denominator for one of the most access-sensitive pediatric subspecialties. citeturn14search11turn18search4turn15search2

The pipeline signal is worse than the stock signal. The recent trend paper covering **2016 to 2024 fellowship cycles** found an **average vacancy rate of 29.8%**, or **18.6 vacant PO&S fellowship slots per year**, with a range from **14 vacancies in 2019** to **23 in 2022**. The same study found that the proportion of available fellowship positions filled by **U.S. graduates** fell from **72% in 2016** to **47% in 2024**. The newer SF Match paper, which analyzed **217 applicants across the 2021-22 to 2023-24 cycles**, shows how small the applicant pool really is: **129 applicants matched into pediatric ophthalmology**, **29 matched another ophthalmology subspecialty**, and **59 did not match**. In a small pipeline, modest shifts in resident interest produce large downstream supply effects. citeturn11search1turn11search4turn9search4

Why are residents not choosing the field? The recent literature points to a coherent mechanism: pediatric ophthalmology is clinically demanding, often Medicaid-heavy, and economically weaker than competing ophthalmology subspecialties. A 2022 survey found that **44.0%** of respondents reported a **10% to 25% decrease in surgical revenue**, **52.2%** reported a **10% to 25% increase in overhead**, **29.6%** were subsidizing income outside pediatric ophthalmology, **11.1%** had stopped operating because of reimbursement cuts, and **37.8%** would not recommend the fellowship. A 2025 resident-exposure study explicitly described pediatric ophthalmology as a field where **almost half of fellowship slots go unfilled annually**. Older salary literature, summarized in later workforce reviews, also identified pediatric ophthalmology as the lowest-paid ophthalmology subspecialty on historical faculty and private-practice salary comparisons, which helps explain the long-running recruitment problem even if the exact dollar figures are older than ideal. citeturn28search3turn24search5turn9search10turn28search7turn24search17

The retirement side compounds the recruitment problem. In the JAMA Ophthalmology retirement-forecasting study, pediatric ophthalmologists had a **median 24 years in practice**, and under the study’s most aggressive retirement assumptions, **23 states** were flagged at risk of underaccess due to retirement-related losses. That model did **not** account for continued fellowship under-fill, so it is better read as a lower-bound warning than a worst-case scenario. Meanwhile, the survey evidence already captured **6.5% of respondents retiring in the prior three years**. Together, the field looks less like a stable equilibrium and more like a specialty whose visible shortages may worsen abruptly once retirements accelerate. citeturn27view0turn24search5

## Geographic access cliff

The U.S. access problem is not subtle. It is a cliff. In the 2022 national cross-sectional study, **90.0% of counties** had **zero** pediatric ophthalmologists, and one year later the 2023 practitioner-type study still found **90.2% of counties** without one. This is the core structural point: the typical American county has no local pediatric ophthalmologist at all. That means the working unit of access is not “Can I find one in my county?” but “How far must I travel into the nearest metro referral basin?” citeturn14search11turn23search2

The 2025 geospatial coverage study makes that more concrete: **about 1 in 7 American children live outside 60 minutes of pediatric ophthalmology care**. That statistic matters more than the county statistic, because counties vary greatly in size and population. A child can technically live in a county with a pediatric ophthalmologist and still face a burdensome trip, while a child in a neighboring county might be near an urban border and have easier access. So the strongest current statement is this: the national county map says the system is sparse, and the drive-time analysis says that sparsity converts into real travel burden for millions of children. citeturn21search2turn20search3

There is also a social-gradient component. Counties without pediatric ophthalmologists had lower household income and worse transportation and connectivity markers in both the 2022 and 2023 analyses, and the more recent practitioner-type study showed that **96.4%** of counties without a pediatric ophthalmologist also lacked a pediatric optometrist. In other words, many of the places with the greatest specialist scarcity also lack a nearby pediatric-eye-care fallback. This is why the access issue is better understood as a pediatric eye-care desert problem, not just a specialist preference problem. citeturn23search2turn23search11turn30search17

The wait-time data point in the same direction. The Medicaid-focused 2023 study found mean wait times of **3.9 months** for new patients and **2.7 months** for non-emergency surgery at academic eye centers and children’s hospitals, which are the same institutions that absorb many Medicaid-insured, complex, and travel-intensive referrals. States with higher Medicaid patient shares had longer waits for new visits. That is exactly what you would expect when a workforce is both thin and financially misaligned: care concentrates in tertiary centers, and then access degrades further at those centers because the payer mix is unfavorable and the total specialist supply is too small. citeturn30search7turn30search13

## Orthoptic leverage and what the US is giving up

The practical case for orthoptics is that pediatric ophthalmology has too much work that **requires high-level binocular-vision and ocular-motility expertise** but does **not always require physician time at every step**. Pediatric strabismus, amblyopia follow-up, sensorimotor examinations, surgical measurements, postoperative alignment checks, neuro-ophthalmic visual assessment, and selected screening pathways are all areas where orthoptists can function as genuine force multipliers when a system is built to use them. The U.S. evidence base is smaller than the UK or Australian one, but it still points the same way. In a U.S. practice-efficiency study, adding a second certified orthoptist increased practice revenue by **more than $70,000** over six months, despite the orthoptist’s higher salary relative to an ophthalmic assistant. The mechanism is straightforward: more specialized delegated work means better physician throughput and more appropriate use of surgeon time. citeturn35search3

Internationally, the evidence is stronger and more operational. In Australia, a cost analysis of an **orthoptist-led neurofibromatosis type 1 screening clinic** found lower mean cost per appointment than consultant-led care, and a scholarly summary reported **mean appointment times of 45.11 minutes in consultant-led clinics versus 25.85 minutes in orthoptist-led clinics**. NSW Health’s orthoptist workforce report documented orthoptist-led clinics that removed **2,044 patients** from a cataract pre-assessment waiting list and reported a significant reduction in pediatric waiting-list numbers through orthoptist-led triage. These are precisely the kinds of gains the U.S. system needs: lower-cost follow-up pathways, faster triage, and fewer consultant slots spent on standardized assessments that an orthoptist can perform with protocolized escalation. citeturn36search2turn36search20turn36search1turn35search16

The UK stroke and neuro-visual pathway literature shows the same logic in another domain. A 2026 *Eye* survey found stroke vision services operating in **66.1%** of orthoptic departments in hospitals with stroke units, but only **27.6%** were funded. NICE evidence reviews explicitly state that access to orthoptists on stroke units has been proposed to improve detection of post-stroke visual problems and accelerate access to management. That is exactly orthoptic leverage: scarce medical specialists are preserved for the highest-complexity decisions, while orthoptists systematically pick up diagnosis, screening, follow-up, triage, and monitoring work that otherwise becomes either specialist backlog or missed care. citeturn35search2turn35search6

The U.S. is also giving up data visibility by not institutionalizing orthoptics more fully. The AOC currently lists **17 accredited orthoptic training programs**, and training is a formal **24-month** program. But there is no robust national registry-quality workforce denominator analogous to what some other systems maintain, and the federal occupation code that nominally covers orthoptists pulls from the residual category **“Healthcare Diagnosing or Treating Practitioners, All Other,”** producing an implausible employment figure of **41,300** that is not usable as a real orthoptist count. That means the U.S. not only under-deploys orthoptists; it also under-measures them. In workforce analysis, invisibility is not neutral. It usually signals that a profession is not fully built into reimbursement, regulation, or planning. citeturn33view0turn32search6turn32search2

The final loop is demand. Pediatric ophthalmology is hit by rising neuro-visual and childhood-eye-health workload from several directions at once. Broader ophthalmology is projected to see a **12% supply decline** and **24% demand increase** from 2020 to 2035, leaving projected workforce adequacy at **70% overall**, **77% in metro areas**, and only **29% in nonmetro areas**. On top of that, pediatric and neuro-visual demand is being pushed by concussion-related visual symptoms, hidden CVI burden, and continuing pediatric screening needs. If the U.S. continues addressing that demand with a thin pediatric ophthalmologist workforce and a marginal orthoptist workforce, it is implicitly choosing slower triage, longer waits, more tertiary-center congestion, and more geographic inequity than systems that deploy orthoptists as a normal part of pediatric and neuro-ophthalmic service design. citeturn37search0turn37search4turn38search4turn38search17turn38search21

## Data gaps

The evidence is strong enough to show a real workforce and access problem, but there are still important questions the current literature cannot answer well.

- **Exact active U.S. pediatric ophthalmologist count.** Recent sources disagree between a directory-based count of about **1,056 to 1,060** and a narrower estimate of **800 to 900** actively providing surgical pediatric ophthalmology care. The difference is probably definitional, but the field lacks a definitive active-practice registry. citeturn14search11turn18search4turn15search2
- **Exact latest-cycle fellowship vacancies for 2024.** Recent literature clearly reports the 2016–2024 average vacancy burden and the declining U.S.-graduate share, but the accessible abstracts and snippets do not expose the exact 2024 vacancy count itself. citeturn11search1turn11search4
- **Direct child-level rural versus urban drive-time distribution.** The best recent paper gives the strong headline that **1 in 7** children live beyond 60 minutes from care, but accessible public summaries do not provide a full rural/urban percentile breakdown. citeturn21search2
- **National U.S. orthoptist headcount, age structure, and annual graduates.** AOC clearly reports **17 accredited programs**, but there is no authoritative national database showing how many orthoptists are actively practicing, their age distribution, annual graduate output, retirement flow, or geographic distribution. The main federal occupation data are too aggregated to solve this. citeturn33view0turn32search2turn32search6
- **Net replacement rate for pediatric ophthalmology and orthoptics.** There are enough fragments to say the pipeline is fragile and retirement risk is real, but not enough clean longitudinal data to calculate a highly defensible national net replacement rate for either profession without stronger assumptions than the evidence supports. citeturn27view0turn11search1turn24search5
- **Comparative U.S. outcome effects of orthoptic deployment.** The evidence that orthoptists improve efficiency is real, especially internationally, but the U.S. still lacks a large contemporary study linking orthoptist staffing density to national differences in wait times, surgery access, amblyopia completion, or postoperative follow-up outcomes. citeturn35search3turn36search2turn36search1
