The global optical coherence tomography market size was valued at USD 2.04 billion in 2025 and is projected to grow from USD 2.28 billion in 2026 to USD 5.46 billion by 2034, registering a CAGR of 11.56% during the forecast period from 2026 to 2034. North America dominated the optical coherence tomography market with a market share of 38.6% in 2025.
Optical coherence tomography is a cutting-edge technique used for cross-sectional imaging with high resolution. Similar to ultrasound imaging, optical coherence tomography is a type of non-invasive imaging technique. This technique uses coherent light to capture images in two and three dimensions. This technique is used to examine transparent tissues. In addition, this technique is employed in the field of ophthalmology to monitor the condition of the retina. During a biopsy, optical coherence tomography is distinguished by its high-resolution imaging and deep penetration. This method can provide live images of tissue. Consequently, it can be utilized in optical biopsies and can reduce sampling errors associated with biopsies.

AI Is Becoming Integrated Directly into OCT Diagnostic Workflows
The Optical Coherence Tomography Market is shifting from image acquisition alone toward AI-supported interpretation. Modern OCT platforms can use deep-learning algorithms to identify abnormal scans, improve segmentation, enhance OCT angiography images, and prioritize cases requiring closer clinical review. This helps ophthalmologists manage growing imaging volumes without manually examining every scan with the same intensity. AI integration is especially relevant for retinal diseases where repeated OCT examinations generate large datasets over time. The trend is expanding competition from hardware specifications toward software, clinical decision support, connectivity, and workflow efficiency. Manufacturers that combine high-resolution imaging with integrated AI can therefore deliver greater value to high-volume eye-care clinics.
In August 2025, ZEISS received CE mark approval for CIRRUS PathFinder, which uses deep learning to automatically identify abnormal macular OCT B-scans and can assess hundreds of scans in real time.
Growing Retinal Disease Burden Is Increasing the Need for Early Imaging
The large global burden of vision impairment is a major driver for OCT adoption because several important eye diseases require detailed examination and long-term monitoring of retinal structures. OCT provides non-invasive cross-sectional imaging that helps clinicians evaluate conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration. As populations age and chronic diseases become more common, ophthalmologists need efficient technologies for detecting structural changes and tracking disease progression. Greater emphasis on early diagnosis also supports repeated OCT use rather than one-time imaging. This creates continuing demand for scanners, software upgrades, image-management platforms, and clinical services across hospitals, specialty eye clinics, research centers, and community-based ophthalmology networks.
In February 2026, WHO reported that at least 2.2 billion people globally have near or distance vision impairment, with glaucoma, diabetic retinopathy, and age-related macular degeneration among major causes.
Unequal Access to Eye Care Limits OCT Deployment in Underserved Regions
OCT systems require equipment investment, trained eye-care professionals, maintenance, interpretation capability, and reliable patient referral pathways. These requirements can restrict adoption in regions where basic eye-care services are already difficult to access. Advanced imaging provides limited benefit when healthcare systems lack enough ophthalmologists or infrastructure to evaluate patients and provide follow-up treatment. This creates a significant difference between technologically advanced eye clinics and underserved communities. Manufacturers must therefore address affordability, usability, training, and service availability if OCT is to expand beyond established specialist centers. Portable systems, teleophthalmology, and automated analysis can reduce some barriers, but broader healthcare access and workforce limitations remain important restraints on global market penetration.
In February 2026, WHO reported that one in two people worldwide who need cataract surgery cannot access it, highlighting the wider eye-care access gap affecting deployment of advanced diagnostic technologies.
OCT Angiography Creates Growth in Non-Invasive Vascular Imaging
OCT angiography is creating an opportunity to expand OCT beyond structural imaging by visualizing retinal and choroidal blood vessels without conventional dye injection. This can strengthen assessment of vascular changes associated with retinal diseases and increase the clinical information generated from one imaging platform. Vendors can capture this opportunity by improving scan speed, image quality, segmentation, wide-field visualization, and software-assisted interpretation. OCT-A also creates opportunities for upgrades within the installed OCT base, allowing providers to add advanced imaging capabilities through compatible hardware and software. As clinicians gain more experience interpreting OCT-A data, the technology can become more deeply integrated into retinal diagnosis, monitoring, research, and personalized treatment planning.
In October 2025, ZEISS showcased CIRRUS AngioPlex OCT-A at AAO 2025, providing non-invasive visualization of retinal and choroidal vasculature alongside its expanding digital ophthalmic workflow.
Imaging Artifacts Can Reduce OCT Reliability and Interpretation Accuracy
Maintaining reliable image quality remains a technical challenge as OCT systems become faster and more detailed. Patient movement, eye position, optical alignment, scanning geometry, and tissue characteristics can create artifacts that distort images or reduce signal quality. These problems are particularly important for automated analysis because AI and segmentation software depend on dependable input data. Manufacturers must therefore improve eye tracking, image registration, artifact correction, acquisition software, and quality-control algorithms while keeping examinations quick and comfortable. The challenge becomes greater as OCT expands into angiography, high-resolution research imaging, and home monitoring, where acquisition conditions may vary more widely than in controlled specialist clinics.
In March 2025, published OCT research identified pupil wobble in point-scanning retinal systems as a source of signal loss and image artifacts and demonstrated pupil tracking as a correction approach.
