The OCT machines provide automated, serial analysis of the nerve fiber layer thickness, cup-to-disc ratio, and other measurements. They can compare the patient’s optic nerve and nerve fiber measurements against age-matched normal patients to show areas of loss.
28 sty 2019 · The table below lists and compares the specs of each OCTA device. For images with a typical field of view (~6 mm) centered on the macula, all OCTA devices can clearly identify superficial and deep retinal vasculatures as well as the choriocapillaris.
1 maj 2010 · 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.
15 wrz 2015 · The Anatomy of an OCT Scan. OCTs—and their printouts—can be tough to understand. Here’s a how-to on differentiating OCT models and reading their scans. By Jarett Mazzarella, OD, and Justin Cole, OD.
11 cze 2023 · 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.
Optical coherence tomography (OCT) is an imaging technique that uses interferometry with short- coherence-length light to obtain micrometer-level depth resolution and uses transverse scanning of the light beam to form two- and three-dimensional images from light reflected from within biological tissue or other scattering media.
