The global optical coherence tomography (OCT) market is likely to expand from USD 1.6 billion in 2025 to USD 4.2 billion by 2035, at an 11.1% CAGR. Ophthalmology remains the anchor, with conditions like age-related macular degeneration, diabetic retinopathy, and glaucoma collectively accounting for over 60% of 2025 revenues.
After 15 years covering global health tech, I’ve learned to spot the quiet revolutions — the ones that don’t make headlines but end up reshaping medicine. Optical Coherence Tomography (OCT) is one of them. It’s fast, non-invasive, and ridiculously precise. And it’s exploding worldwide.

OCT Is Saving Vision — And Could Save Lives
Let’s be clear. OCT is already indispensable in ophthalmology. It catches diseases like macular degeneration, diabetic retinopathy, and glaucoma before symptoms even show. It’s fast, painless, and accurate. It changes outcomes.
But the technology is breaking out of its silo. In cardiology, it helps guide stents with pinpoint accuracy. In dermatology, it images skin layers in real time. In oncology, it’s showing promise in early tumor detection. The future is here — and it’s scanning you with light.
FMI’s report highlights the explosion of portable and AI-powered OCT devices. These aren’t lab curiosities anymore — they’re clinical tools being deployed in real hospitals. But too often, not in American ones.
The U.S. Is Leading — Technically. Not Clinically.
Here’s the paradox: the U.S. leads the world in market size. But we’re failing to get this tech into the hands of the clinicians who need it most. Outside elite academic hospitals and specialist clinics, OCT remains out of reach. Too expensive. Too complex. Too “optional.” That’s unacceptable.
We’re spending billions on end-stage care while ignoring diagnostic tools that could prevent it. That’s not just inefficient — it’s negligent.
It’s Not Just a Tech Story. It’s a Healthcare Justice Issue.
Think rural clinics in the Midwest. Think overworked physicians in city ERs. Think underfunded community health centers. These are the front lines of American healthcare. And they’re largely locked out of the OCT boom.
According to FMI, portable OCT systems are projected to grow at 9.7% CAGR — the fastest segment. That’s exactly the kind of tool these clinics need. But without funding, support, and reimbursement reform, it won’t matter.
Let’s not pretend this is just about innovation. It’s about access. It’s about equity. It’s about whether a working-class patient in Arkansas gets the same early diagnosis as a retiree in Boston. Right now, the answer is no.
We Can’t Afford to Wait
If OCT were a drug, we’d be fast-tracking it through the FDA and hailing it as a miracle. But because it’s a device — and because it threatens entrenched, expensive workflows — it’s not getting the urgency it deserves.
Enough with that. We need:
- Full Medicare and insurer reimbursement across specialties
- National funding to get OCT into rural and community clinics
- Mandatory integration into medical training
- Public-private investment in AI-enabled OCT platforms
