The Next Generation of OCT Technology Poised to Take Off and How AI is Reshaping the Future of OCT
May 29 , 2025
When OCT meets artificial intelligence, a diagnostic revolution quietly arrives: Automatic lesion identification: The algorithm based on convolutional neural network (CNN) can complete the pathological analysis of ophthalmic OCT images within 0.3 seconds, identifying dozens of lesions such as macular holes and retinal detachment, with an accuracy rate exceeding 95% Real-time surgical navigation: D...

Sudden blurring of vision could be a red alert for a systemic illness
Jul 10 , 2025
Exudative Retinal Detachment (ERD) is a lesion in which the neuroepithelial layer of the retina separates from the pigment epithelial layer without holes. The core mechanism is the destruction of the blood-retinal barrier or the imbalance of choroidal osmotic pressure, resulting in abnormal accumulation of plasma, lipids or blood in the subretinal space. Unlike rhegmatogenous or tractional detachm...

How does Optical Coherence Tomography reduce motion artifacts?
Aug 08 , 2025
1.Improvements at the hardware level (1) Increase the scanning speed Frequency domain OCT (FD-OCT) : Compared with time domain OCT (TD-OCT), FD-OCT has A faster scanning speed (up to tens of thousands to hundreds of thousands of A-scans per second), significantly reducing artifacts caused by patients' minor movements (such as eye tremors and breathing). Swept-frequency OCT (SS-OCT) : By rapidly tu...

Understanding Optical Coherence Tomography Technology in One Article.

I. What is OCT? A Core Metaphor Let's understand OCT through a vivid analogy: Imagine a fresh sandwich. A regular camera can only capture its top view (a two-dimensional photo). OCT, however, acts like a precise “optical scalpel.” It can slice the sandwich layer by layer without damage, capturing ultra-high-resolution images of each component (bread, vegetables, meat slices). These cross-sectional...
