En face swept-source optical coherence tomography (SS-OCT) and SS-OCT angiography findings of retinal astrocytic hamartomas in patients with tuberous sclerosis complex [PDF]

Frontiers in Medicine
IntroductionTuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by multisystem hamartomas, including retinal astrocytic hamartomas (RAHs), which are a key diagnostic criterion.

Surgical microscope integrated MHz SS-OCT with live volumetric visualization. [PDF]

Biomed Opt Express, 2023
Intraoperative optical coherence tomography is still not overly pervasive in routine ophthalmic surgery, despite evident clinical benefits. That is because today’s spectral-domain optical coherence tomography systems lack flexibility, acquisition speed, and imaging depth.

In vivo SS-OCT imaging of crystalline lens sutures. [PDF]

Biomed Opt Express, 2020
We demonstrate in vivo three-dimensional (3-D) visualization of crystalline lens sutures in healthy eyes using swept source optical coherence tomography (SS-OCT). Volumetric data sets of the crystalline lenses were acquired and processed to obtain enhanced contrast projection images and to extract suture patterns in both anterior and posterior lens ...

Evaluation of Incipient Enamel Caries at Smooth Tooth Surfaces Using SS-OCT. [PDF]

Materials (Basel), 2022
(1) Background: Dental caries, if diagnosed at the initial stage, can be arrested and remineralized by a non-operative therapeutic approach preserving tooth structure. Accurate and reproducible diagnostic procedure is required for the successful management of incipient caries.

Analysis of injured-skin SS-OCT images based on combined attention UNet. [PDF]

PLoS One
Optical coherence tomography (OCT) is a noninvasive imaging technique that provides high-resolution images of superficial skin tissues and has become widely used for diagnosing various skin disorders. Assessing laser-induced skin tissue damage is essential for understanding the healing mechanisms and optimizing treatment strategies.

Validity of Automated Choroidal Segmentation in SS-OCT and SD-OCT. [PDF]

Invest Ophthalmol Vis Sci, 2015
To evaluate the validity of a novel fully automated three-dimensional (3D) method capable of segmenting the choroid from two different optical coherence tomography scanners: swept-source OCT (SS-OCT) and spectral-domain OCT (SD-OCT).One hundred eight subjects were imaged using SS-OCT and SD-OCT.

Longitudinal SS-OCT choroidal imaging following thrombosis of the superior ophthalmic vein. [PDF]

Am J Ophthalmol Case Rep
To report longitudinal changes in choroidal thickness and the choroidal vasculature using SS-OCT imaging in a patient with superior ophthalmic vein thrombosis (SOVT).In a 93-year-old woman with a left-sided SOVT, the choroid in the left eye was thickened and the choroidal vessels were dilated both superiorly and inferiorly, with greater changes evident
