Understanding Pseudopapilledema on Spectral Domain Optical Coherence Tomography
Indian Journal of Ophthalmology, 2022 Abstract Objective: Optic nerve head drusen (ONHD), peripapillary hyperreflective ovoid mass like structures (PHOMS) and horizontal hyperreflective lines (HHL) are commonly seen in eyes with pseudopapilledema on spectral domain optical coherence tomography (SDOCT) .The objective of this study is to ...

Spectral Domain Optical Coherence Tomography and Glaucoma [PDF]
International Ophthalmology Clinics, 2008 Glaucoma may be the second leading cause of blindness in the world, affecting about 60 million people globally.1,2 The true prevalence may be underestimated as up to half of patients with glaucoma are undiagnosed, and a large proportion of glaucoma patients who are eligible for registration as legally blind remain unregistered.3–7 Glaucoma is a ...

Quantum-inspired detection for spectral domain optical coherence tomography [PDF]
Optics Letters, 2020 Intensity levels allowed by safety standards (ICNIRP or ANSI) limit the amount of light that can be used in a clinical setting to image highly scattering or absorptive tissues with optical coherence tomography (OCT). To achieve high-sensitivity imaging at low intensity levels, we adapt a detection scheme—which is used in quantum optics for providing ...

Spectral-Domain Optical Coherence Tomography for Glaucoma Diagnosis [PDF]
The Open Ophthalmology Journal, 2015 Identification of structural damage to the optic nerve and retinal nerve fiber layer (RNFL) is an essential component of diagnosis and management of glaucoma. The introduction of spectral-domain OCT (SD-OCT) has allowed objective quantification of damage to these structures with unprecedented resolution.

Spectral-Domain Optical Coherence Tomography for Macular Edema [PDF]
The Scientific World Journal, 2014 Optical coherence tomography (OCT) is a rapid noncontact method that allows in vivo imaging of the retina and it has become an important component in clinical practice. OCT is a useful ancillary tool for assessing retinal diseases because of its ability to provide cross-sectional retinal images and quantitatively analyze retinal morphology.

Orthogonal dispersive spectral-domain optical coherence tomography
Optics Express, 2014 Ultrahigh depth range spectral domain optical coherence tomography (SDOCT) can be realized based on the orthogonal dispersive spectrometer consisted by a high spectral resolution virtually-imaged phased array (VIPA) and a low spectral resolution grating.

Multirate Spectral Domain Optical Coherence Tomography
IEEE Photonics Journal, 2023 Optical coherence tomography is state-of-the-art in non-invasive imaging of biological structures. Spectral Domain Optical Co-herence Tomography is the popularly used variation of this technique, but its performance is limited by the bandwidth and res-olution of the system.

Toward Spectral-Domain Optical Coherence Tomography on a Chip
IEEE Journal of Selected Topics in Quantum Electronics, 2012 We present experimental results of a spectral-domain optical coherence tomography system based on an integrated optical spectrometer. A 195-channel arrayed-waveguide-grating (AWG) spectrometer with 0.4-nm channel spacing centered at 1300 nm and a 125-channel AWG with 0.16-nm channel spacing centered at 800 nm have been fabricated in silicon oxynitride ...

CHOROIDAL IMAGING USING SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY [PDF]
Retina, 2012 A structurally and functionally normal choroidal vasculature is essential for retinal function. Therefore, a precise clinical understanding of choroidal morphology should be important for understanding many retinal and choroidal diseases.PUBMED (http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed) was used for most of the literature search for this ...

The promise of spectral-domain optical coherence tomography [PDF]
Expert Review of Ophthalmology, 2008 Optical coherence tomography (OCT) was first reported in 1991 [1]. Since then, improved resolution and speed have enabled OCT to become widely used clinically in ophthalmology.
