Lecture: Retinal OCT for Clinicians Cybersight.
During this Live Lecture, the basics behind retinal OCT are reviewed, followed by normal anatomic correlations and then OCT assessment of retinal conditions. Finally, structure-function correlations are discussed. To translate please select your language to the right of this page. DR CIULLA: And I will be speaking on optical coherence tomography, or OCT, for clinicians. Well, as many of you know, OCT is non-contact and non-invasive. It provides micron resolution of the retina and optic nerve.

The ABCs of OCT.
Once the findings in normal eyes are appreciated, the transition to detecting variations in different retinal, choroidal and vitreal abnormalities will be simplified greatly. SD-OCT scans most often are presented as a cross-section of the retina, which appears as a typical histological slice in anatomy textbooks. By convention, the inner retina is close to the center of the eyethe vitreousand the outer retina is close to the choroid and sclera. Remember that the outer retina contains the RPE and the photoreceptors, and the inner retina contains the retinal nerve fiber layer RNFL and the ganglion cells. Think of OCT technologys role as identifying changes in optical density, which are depicted either in color or grayscale.

What Is Optical Coherence Tomography? American Academy of Ophthalmology.
Optical coherence tomography OCT is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retinas distinctive layers. This allows your ophthalmologist to map and measure their thickness.

With three new chapters and expansive amount of section updates, this source supplies the latest studies on OCT imaging, experimental treatments, new applications for thermal lasers, and gene therapy for AMD. The source also summarizes studies from current clinical trials to remain the gold standard in the provision of care for patients with this disabling disorder.
The Retinal Nerve Fiber Layer Thickness in Ocular Hypertensive, Normal, and Glaucomatous Eyes With Optical Coherence Tomography. Glaucoma JAMA Ophthalmology JAMA Network.
Conclusion These findings suggest that quantitative differences in RNFL thickness exist between age-matched ocular hypertensive, normal, and glaucomatous eyes. OPTICAL COHERENCE tomography OCT is one promising technology that has been developed to assess tissue thickness in vivo, such as that of the retinal nerve fiber layer RNFL. This technology was initially designed for fiberoptic use. 1 Early biological uses of this technology involved imaging of the human anterior chamber, peripapillary retina, and coronary artery.
