Swept Source Optical Coherence Tomography: a Review

Current Ophthalmology Reports, 2018
In this review, we shall attempt to explain the physics behind swept source-optical coherence tomography (SS-OCT), the advantages and disadvantages of SS-OCT when compared with spectral domain-optical coherence tomography (SD-OCT), and the current clinical applications of SS-OCT.

Swept-Source Optical Coherence Tomography

2016
In the two decades since optical coherence tomography (OCT) was first described (Huang et al. 1991), this technology has played essential roles in ophthalmology as well as other branches of medicine. The technology has been adapted to produce noninvasive, high-resolution images of both the anterior segment (cornea and structures at the angles) and ...

Swept source Fourier domain optical coherence tomography

Optical Amplifiers and Their Applications/Coherent Optical Technologies and Applications, 2006
Swept laser based Fourier domain optical coherence tomography (FDOCT) systems were designed and developed. 3-D structure, Doppler and polarization imaging with high speed and high sensitivity were described and ...

Handheld common-path swept-source optical coherence tomography angiography

Optics Letters, 2023
This study develops a handheld optical coherence tomography angiography (OCTA) system that uses a high-speed (200 kHz) swept laser with a dual-reference common-path configuration for stable and fast imaging. The common-path design automatically avoids polarization and dispersion mismatches by using one circulator as the primary system element, ensuring

SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS IN WAARDENBURG SYNDROME

RETINAL Cases & Brief Reports, 2021
Purpose: Waardenburg syndrome (WS) is a rare condition characterized by six main features. It has been previously observed that WS is also associated with hypopigmentation of the choroid through multimodal imaging. To our knowledge, this is the first report of using swept-source optical coherence tomography angiography (OCTA ...

Retinal applications of swept source optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)

Progress in Retinal and Eye Research, 2021
The advent of optical coherence tomography (OCT) revolutionized both clinical assessment and research of vitreoretinal conditions. Since then, extraordinary advances have been made in this imaging technology, including the relatively recent development of swept-source OCT (SS-OCT).

Air-puff Swept-Source Optical Coherence Tomography

Frontiers in Optics 2016, 2016
The response of porcine eyes to air puff at well controlled levels of intraocular pressure (IOP) was visualized and quantified using air-puff combined with Swept-Source OCT instrument. The viscoelastic properties of the corneas of model animals appeared as a hysteresis of the deformation amplitude vs. applied air pressure. The corneal apex displacement

Image artefacts in swept-source optical coherence tomography angiography

British Journal of Ophthalmology, 2016
To describe optical coherence tomography angiography (OCTA) image artefacts in eyes with and without ocular pathologies.The OCTA images of healthy subjects and patients with age-related macular degeneration, diabetic retinopathy and retinal vascular occlusions were retrospectively reviewed.

Swept-source optical coherence tomography angiography in serpiginous choroiditis

British Journal of Ophthalmology, 2017
Background/AimsTo analyse choroidal vascular density of affected and non-affected areas in active and inactive serpiginouschoroiditis (SC) by means of optical coherence tomography angiography (OCT-A).MethodsIn this cross-sectional and observational study, 22 eyes of 11 patients diagnosed with SC were included.
