Ophthalmologists and retinal specialists interested in cutting-edge diagnostic imaging technology for eye care.
TL;DR
This video highlights advancements in ultra-widefield OCT and OCTA technology presented at the EURETINA 2025 symposium. Experts discuss how new imaging capabilities offer faster, more precise diagnostics for a wider range of retinal diseases, potentially replacing traditional methods like fluorescein angiography.
Key Takeaways
- Ultra-widefield OCTA offers a non-invasive alternative to fluorescein angiography, providing detailed views of retinal vasculature without patient discomfort or dye-related risks.
- New OCT technology enables rapid acquisition of peripheral retinal images, significantly improving the detection and management of lesions previously missed by standard central scans.
- The advanced OCT system allows for precise visualization and quantification of vascular density in both superficial and deep retinal plexuses, aiding in disease assessment.
- Volume rendering and 3D imaging capabilities of the OCT system help differentiate between various pathologies, such as melanomas and other lesions, improving diagnostic accuracy.
- Ultra-widefield OCTA is particularly beneficial for imaging pediatric patients and those with diabetic retinopathy or ischemic conditions, expanding diagnostic reach.
- The speed and resolution of the new OCT devices facilitate easier identification of subtle pathologies like vitreous detachment and choroidal neovascularization.
- Multimodal imaging combining OCTA with high-resolution B-scans provides comprehensive insights into macular and vitreomacular conditions, enhancing treatment planning.
- The integration of AI into OCT machines is the logical next step for precise, automated measurements of observed retinal structures and pathologies.

Questions & Answers
What is the main advantage of the new 400,000 a scan per second OCT?
The new OCT offers a much faster scan speed, allowing for imaging of the periphery and reducing acquisition time to around 10 seconds for a patient.
How does ultra-wide field OCTA compare to traditional methods like FA and ICG?
Ultra-wide field OCTA is non-invasive, acceptable to patients, and provides detailed images of the choroid and retina without the need for injections.
Can ultra-wide field OCTA replace fluorescein angiography (FA) and ICG?
OCTA is already replacing FA for conditions like diabetic retinopathy and ischemic conditions. It may also replace ICG in the future.
What are the benefits of Torpy's Bemeiser and Yaoade OCT solutions?
These solutions offer speed, precision, and improved outcomes, with features like high resolution, short acquisition times, and the ability to visualize lesions in the periphery.
How does OCTA help in detecting polyps?
While ICG is the gold standard, this new OCT imaging can visualize polyps with great definition, offering a non-invasive alternative for detection.
What is the role of AI in OCT machines?
AI is the next step for OCT machines, enabling precise measurements of what is seen, leading to more accurate diagnoses and treatment monitoring.
Key Terms
- OCT — Optical Coherence Tomography is an imaging technique that uses light waves to capture cross-section images of the retina and optic nerve.
- OCTA — Optical Coherence Tomography Angiography is a non-invasive imaging test that uses OCT technology to visualize blood flow in the retina.
- Ultra-wide field imaging — An advanced imaging technique that captures a much larger area of the retina than traditional methods, including the periphery.
- Vascular density analysis — A quantitative analysis that measures the density of blood vessels within specific layers of the retina.
