![]() The amount of energy directed into the eye in both cases, 600 μW, is less than that of the Stratus OCT3 and is safe for intrabeam viewing for up to 8 hours at the same retinal location.Ĭonclusion Spectral domain optical coherence tomography technology enables ophthalmic imaging with unprecedented simultaneous ultra-high speed and ultra-high resolution. In the past decade, SD-OCT images have shown excellent morphologic. Using a different source in a slightly slower configuration, single images consisting of 500 A-scans were acquired in 34 ms, allowing imaging at 29 frames per second at an axial resolution of 3.5 μm, which is 3 times better than commercially available optical coherence tomography instruments. Spectral-domain OCT (SD-OCT) has enabled high-speed scanning and improved image resolution. Enter the email address you signed up with and well email you a reset link. Spectral Domain Optical Coherence Tomography in Glaucoma - EyeWiki This is a review of the utility of spectral-domain optical coherence tomography in the diagnosis and management of glaucoma. Single images (B-scans) consisting of 1000 A-scans were acquired in 34.1 ms, allowing video rate imaging at 29 frames per second with an axial resolution of 6 μm. Glaucoma Diagnostic Performance of Macular and Retinal Nerve Fiber Layer by Spectral-Domain Optical Coherence Tomography. It will provide a brief review of all modalities, but focus primarily on the Cirrus machine. Results In vivo images of the retina, the optic nerve head, and retinal blood flow were obtained at an ultra-high speed of 34.1 microseconds (ms) per A-scan, which is 73 times faster than commercially available optical coherence tomography instruments. Spectral Domain Optical Coherence Tomography in Glaucoma - EyeWiki This is a review of the utility of spectral-domain optical coherence tomography in the diagnosis and management of glaucoma. The AWG has a footprint of only 3.0 cm × 2. Methods Using a superluminescent diode source, a clinically viable ultra-high speed, ultra-high resolution spectral domain optical coherence tomography system was developed. The clinical response was documented on serial spectral domain optical coherence tomography (OCT) imaging, with image registration. Abstract We designed and fabricated an arrayed-waveguide grating (AWG) in silicon oxynitride as a spectrometer for spectral domain optical coherence tomography (SD-OCT).
