What Is Optical Coherence Tomography? - American Academy of Ophthalmology
Sep 26, 2024 · Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) are non-invasive imaging tests. They use light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers and the optic nerve fiber layer.
Optical Coherence Tomography (OCT) Eye Test: What It Is - Cleveland Clinic
Sep 24, 2024 · Optical coherence tomography (OCT) is a noninvasive imaging method that uses reflected light to create pictures of the back of your eye. It helps eye care providers diagnose and manage common eye diseases like diabetes-related retinopathy and glaucoma.

May 7, 2024 · OCT stands for optical coherence tomography. An OCT scan is an advanced eye test that provides incredibly detailed images of the back of your eye, including the retina, optic nerve, and deeper layers. How does an OCT scan differ from other eye tests?
Learning to read retinal OCT | Ophthalmology Management
Jul 1, 2015 · This noninvasive imaging technique produces high-resolution cross-sectional images of the retina, anterior segment, optic nerve head and retinal nerve fiber layer. OCT employs low-coherence interferometry of near-infrared light to acquire views of the eye, which resemble histological sections.
OCT: How It Works and When to Use It
Jun 12, 2019 · SD-OCT provides two- and three-dimensional images with nearcellular resolution (<10 μm). It uses a long-wavelength (near-infrared), broad-bandwidth light source to illuminate the retina and assess the light reflected from retinal tissue interfaces using a spectrometer and Fourier transformation.
