OCT is a non-contact, cross-sectional imaging modality providing high-resolution images of the macula. Summary of the diseases in this article: Wet age-related macular degeneration (AMD)

2024年9月26日 · 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.

2005年11月1日 · With AMD patients, for example, OCT is good at detecting subretinal fluid and differentiating it from increased retinal thickness. It also shows the anatomical changes that can occur in a way that fluorescein angiography does not.

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.

Optical coherence tomography (OCT) is a noninvasive imaging method that eye care specialists use to produce cross-sectional images of your eye. It works by measuring wavelengths of infrared light that reflect off the back of your eye (your retina ).

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.

2019年6月12日 · Optical coherence tomography (OCT) is the gold-standard imaging modality for monitoring the posterior segment and a technique that residents will encounter early on in their training. This article provides a concise summary of how OCT works and also offers some common disease presentations.

Optical coherence tomography (OCT) is an emerging technology for performing high-resolution cross-sectional imaging. OCT is analogous to ultrasound imaging, except that it uses light instead of sound. OCT can provide cross-sectional images of tissue structure on the micron scale in situ and in real time. Using OCT in combination with catheters ...

2020年1月1日 · Optical coherence tomography (OCT) is a noninvasive imaging technique that has been used increasingly to diagnose and manage a variety of retinal diseases. OCT enables micrometer-resolution retinal imaging both at the optic nerve head and the macula. It has become an established imaging modality in ophthalmology.

Optical coherence tomography (OCT) is a high resolution cross-sectional imaging modality initially developed for retinal imaging. Anterior segment OCT (ASOCT) imaging was first described in 1994 by Izatt et al using the same wavelength of light as retinal OCT, namely 830nm. This wavelength is suboptimal for imaging the angle due to limited ...
