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.

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 ...

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 ...

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.

Multimodal imaging of type 1 aneurysmal telangiectasia in a Turkish female with giant arteriovenous aneurysmal malformation

Therapeutic Advances in Ophthalmology, 2019
We present a case with giant arteriovenous aneurysmal malformation with different imaging modalities, including fundus photography, fundus fluorescein angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography.

Balanced detection for spectral domain optical coherence tomography

Optics Express, 2013
The use and advantages of applying balanced-detection (BD) operation method to high speed spectral domain optical coherence tomography (SDOCT) are presented in this study, which we believe is the first such demonstration. Compared to conventional SDOCT, BD-SDOCT provides two unique advantages.

MOGAD Is the Most Common Cause of Isolated Optic Neuritis in Children

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives The study aimed to characterize the clinical features, etiologies, and outcomes of isolated, first‐time pediatric ON in the post‐MOG‐IgG era. Methods This was a single‐center retrospective cohort study at Texas Children's Hospital of patients diagnosed with first‐time ON between 2018–2024, with follow‐up data collected through 2025.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.
