OCT shows you structure. OCTA shows you perfusion. A standard optical coherence tomography (OCT) scan answers the question "what does this tissue look like?" — it renders the retinal layers as a cross-section, micrometer …
In modern ophthalmology, early detection is the ultimate cornerstone of preventing irreversible vision loss. As conditions like age-related macular degeneration (AMD), diabetic retinopathy, and glaucoma continue to rise …
The combination of artificial intelligence (AI) and optical coherence tomography (OCT) is revolutionizing the diagnostic model of ophthalmic diseases. The core of this integration lies in combining the powerful data …
The first step: Demarcate the boundaries of the “safe” and the environment (regional boundary security) OCT devices should not be directly exposed to public networks. First, it is necessary to plan the security domain. …
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 …
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 …
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 …
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 …
Common causes: tractional retinal detachment (TRD) is mainly caused by the traction of the fibrous vascular membrane on the surface of the retina or within the vitreous. Adult TRD is most commonly seen in proliferative …
Optical coherence tomography (OCT) is a valuable imaging technology with diverse applications in medicine, particularly in ophthalmology and cardiology. Its utility depends on the clinical context, but here’s a …
