Global Optical Coherence Tomography (OCT) Market Projected To Reach USD 4.2 Billion by 2035

NEWARK, Del., Jan. 22, 2026 /PRNewswire/ — The global optical coherence tomography (OCT) market is forecast to expand at a compound annual growth rate (CAGR) of 11.1%, increasing from USD 1.6 billion in 2025 to USD 4.2 billion by 2035. The market’s growth reflects a structural transition in medical imaging, where OCT is evolving from an ophthalmology-centric diagnostic tool into a multi-specialty, point-of-care, and AI-enabled imaging platform.

Ophthalmology remains the primary revenue anchor, accounting for over 60% of global revenues in 2025, driven by the rising prevalence of age-related macular degeneration, diabetic retinopathy, and glaucoma. At the same time, non-ocular applications—particularly cardiovascular OCT, which guides approximately 1.5 million coronary interventions annually—are expanding rapidly, alongside emerging adoption in dermatology, oncology, veterinary imaging, and industrial inspection.

Key Market Snapshot (Executive Signals)

Market Size (2025): USD 1.6 billion
Forecast Value (2035): USD 4.2 billion
CAGR (2025–2035): 11.1%
Largest Application (2025): Ophthalmology (69.2%)
Leading Technology: Spectral Domain OCT (59.4% share)
Regional Leader: North America (~40% market share)
Fastest-Growing Region: Asia-Pacific

Growth Drivers Reshaping OCT Adoption

Market expansion is being driven by four converging forces:

Rising chronic disease burden, particularly diabetes-related eye disorders
Hospital capital budgets reopening, accelerating replacement cycles delayed during the pandemic
AI-driven imaging analytics, improving diagnostic speed and accuracy
Miniaturization and portability, expanding point-of-care and mobile screening

Investor confidence is strengthening. Venture funding for portable OCT startups exceeded USD 350 million in 2024, signaling sustained interest in decentralized diagnostic models.

Technology Landscape: SD-OCT Dominates, SS-OCT Accelerates

Spectral Domain OCT (SD-OCT) is projected to account for 59.4% of the global OCT market in 2025, supported by its high-resolution imaging and fast acquisition speeds, particularly in ophthalmology. SD-OCT remains the clinical standard for diagnosing and monitoring glaucoma, diabetic retinopathy, and macular degeneration.

At the same time, Swept Source OCT (SS-OCT) adoption is accelerating due to deeper tissue penetration, wider imaging fields, and faster scan speeds. These capabilities make SS-OCT increasingly relevant for cardiology, complex ophthalmic cases, and industrial quality inspection. Advances in tunable laser sources are further enhancing diagnostic precision.

Recent product innovation highlights this shift. Heidelberg Engineering’s ANTERION and the SPECTRALIS OCTA module exemplify swept-source advances, while FDA-approved handheld systems such as Optomed Aurora are expanding access to AI-enabled diabetic retinopathy screening in primary care settings.

Ophthalmology Remains Core, New Segments Scale

Ophthalmology is projected to maintain a 69.2% market share in 2025, driven by routine screening, disease monitoring, and the adoption of OCT angiography, which enables non-contrast visualization of retinal vasculature.

Beyond clinical ophthalmology, industrial OCT applications are emerging as a material growth segment, projected to reach USD 1.2 billion by 2025. OCT’s non-destructive testing (NDT) capability supports quality control in semiconductors, aerospace components, electronics, and precision manufacturing, where internal structural inspection is critical.

Regulatory Environment Tightens, Trust Becomes a Differentiator

Regulatory scrutiny is intensifying across major markets. Europe’s Medical Device Regulation (MDR) now mandates comprehensive post-market surveillance, prompting manufacturers such as Carl Zeiss Meditec and Topcon to invest in real-world evidence registries.

In the United States, the FDA’s Digital Health Center of Excellence is actively evaluating adaptive AI-based OCT segmentation algorithms, streamlining software-as-a-medical-device approvals while reinforcing clinical trust, transparency, and compliance.

As Carl Zeiss Meditec CEO Ludwin Monz noted during a March 2025 earnings call, advancements in swept-source platforms and AI analytics are expanding diagnostic precision and reinforcing clinician confidence across ophthalmology and adjacent specialties.

Regional Growth Signals

North America: ~40% market share, supported by Medicare reimbursement for OCT angiography and strong hospital adoption
Europe: Growth led by Germany, the UK, and France, driven by preventive care policies and regulatory rigor
Asia-Pacific: Fastest-growing region, fueled by public screening programs and mobile OCT deployment

China has expanded subsidized retinal OCT screening to 18 million additional diabetic patients annually, while India’s Ayushman Bharat initiative is piloting mobile OCT vans to improve rural healthcare access.

Challenges and Opportunity Outlook

Key Constraints

High capital cost of OCT systems
Dependence on trained imaging professionals
Regulatory complexity and uneven reimbursement

Growth Opportunities

AI-enabled diagnostics and automated screening
Portable and low-cost OCT systems
Expansion into oncology, neurology, and telemedicine
Industrial non-destructive testing applications

Competitive Landscape: Innovation Over Scale

The market remains competitive, led by Carl Zeiss Meditec (28% share), followed by Topcon, Heidelberg Engineering, Abbott, and NIDEK. Competitive differentiation is increasingly defined by AI integration, workflow efficiency, regulatory compliance, and multi-application versatility, rather than hardware alone.
