View of the normal retina with OCT. The macular OCT can be used to evaluate the premacular vitreous, macula, and choroid. We’ll look at the OCT through a number of common diseases. Below, we’ve highlighted a few diseases with their common OCT findings: View of the retinal pathologies with OCT Age-related macular degeneration (AMD)

Optical coherence tomography (OCT) is an optical analog of ultrasound imaging that uses low coherence interferometry to produce cross-sectional images of the retina. It captures optical scattering from the tissue to decode spatial details of tissue microstructures.

2023年6月11日 · Optical coherence tomography (OCT) enables ophthalmologists to measure retina thickness on a cellular level and has revolutionized the way we practice ophthalmology. Considering how ubiquitous this technology is, it’s essential that you are able to interpret these 3D reconstructions. But have no fear!

2024年9月26日 · Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye.

2015年9月15日 · OCTs—and their printouts—can be tough to understand. Here’s a how-to on differentiating OCT models and reading their scans. Optical coherence tomography (OCT) has evolved over the last several years from a device used in only a few practices to one found in many primary eye care clinics.

Optical coherence tomography (OCT) is a high-resolution imaging technique with most of its applications in medicine and biology. OCT uses coherent near-infrared light to obtain micrometer-level depth resolved images of biological tissue or other scattering media.

2010年5月1日 · Optical coherence tomography (OCT) has revolutionized the diagnostic field of retina in many different ways. Here is a quick primer on how to read an OCT. (This example involves the Stratus Time-Domain model by Carl Zeiss Meditec, Inc., Dublin, Calif.) 1.

2025年1月27日 · Approaching a basic OCT interpretation. Step 1: With an OCT Macula, identify the retinal layers. Recognize the normal anatomy: RNFL, GCL, IPL, INL, OPL, photoreceptor layer, RPE, and choroid. Step 2: Look for abnormal fluid. Check for intraretinal fluid, subretinal fluid, or cystic spaces. Step 3: Assess retinal thickness.

OCT was first introduced in 1991 Due to the transparency of the eye (i.e. the retina can be viewed through the pupil), OCT is an invaluable ophthalmic diagnostic tool. Time domain to Spectral/Fourier Domain Time vs Spectral Domain OCT
