Optical coherence tomography market seen reaching $4.04 billion by 2030

The optical coherence tomography market is projected to grow from $2.1 billion in 2025 to $4.04 billion by 2030, driven by demand for early disease detection, AI-enabled imaging and broader use beyond ophthalmology. North America led the market in 2025, while Asia-Pacific is expected to grow fastest through 2030.

Why it matters: - Optical coherence tomography is becoming a broader diagnostic tool, not just an eye-imaging technology. - The market’s growth reflects rising demand for early detection, non-invasive imaging and point-of-care diagnostics across more specialties. - Diabetes-related eye disease is a major driver because diabetic retinopathy needs earlier screening and monitoring.

What happened: - The Business Research Company projected the optical coherence tomography market will rise from $2.1 billion in 2025 to $2.4 billion in 2026. - The market is forecast to reach $4.04 billion by 2030. - The report said the market is expanding at a 14.2% CAGR from 2025 to 2026 and a 14.0% CAGR through 2030. - The company released a free sample of the market report and the full report online: the free sample and the full report.

The details: - Optical coherence tomography uses non-invasive optical imaging to produce real-time, in situ images of biological tissue. - The technology delivers high-resolution cross-sectional images used for medical diagnosis. - Growth from 2025 to 2026 was linked to rising retinal disease cases, wider use of ophthalmic diagnostics, preference for minimally invasive imaging, expansion in cardiovascular imaging and continued improvements in optical imaging systems. - Forecast growth through 2030 is tied to early disease detection, expanding use in oncology and dermatology, point-of-care diagnostics, AI-based image analysis and better imaging speed and resolution. - Diabetes is a major catalyst because rising global diabetes rates increase the risk of diabetic retinopathy. - The World Health Organization reported in September 2023 that diabetes caused 2.0 million deaths. - North America held the largest share of the market in 2025. - Asia-Pacific is expected to be the fastest-growing region during the forecast period. - The report also covers South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - The 2026 report package includes market attractiveness scoring, TAM analysis, company scoring matrix graphics and tables, Excel-based dashboards, market hotspots infographics, and updated technology and future-trend analysis.

Between the lines: - The forecast suggests OCT is moving deeper into broader medical imaging workflows as AI and faster hardware improve clinical utility. - Regional growth patterns point to mature adoption in North America and faster expansion in markets with rising healthcare investment. - The diabetes connection shows how chronic-disease burden continues to shape demand for diagnostic imaging.

What's next: - The market’s next phase likely centers on wider clinical adoption outside ophthalmology and stronger integration of AI-assisted interpretation. - Growth will likely depend on how quickly providers adopt point-of-care systems and higher-resolution imaging platforms. - The Business Research Company is offering investor and market intelligence materials alongside the report, including regional and company-level analysis.
