Retinal phantom applicable to OCT, OCT-angiography, and fundus angiography

Design and Quality for Biomedical Technologies XIV, 2021
The retinal imaging system, such as optical coherence tomography (OCT), OCT-angiography (OCTA) and fluorescein angiography (FA), is the important subject for ophthalmic. The use of such equipment continues to increase and retinal phantoms have also been developed to evaluate and modify its performance and image quality.

Navigating the White Dot Syndromes with Optical Coherence Tomography (OCT) and OCT Angiography (OCT-A)

Ocular immunology and inflammation, 2022
Introduction White dot syndromes are a heterogeneous group of diseases that affect different layers in the retina and choroid. Multimodal imaging is fundamental in the diagnosis, but also can be crucial in unveiling the pathogenesis of these entities ...

Structural OCT and OCT angiography biomarkers associated with the development and progression of geographic atrophy in AMD

Graefe's Archive for Clinical and Experimental Ophthalmology
Geographic atrophy (GA) is an advanced, irreversible, and progressive form of age-related macular degeneration (AMD). Structural optical coherence tomography (OCT) and OCT angiography (OCTA) have been largely used to characterize this stage of AMD and ...

Anterior Segment OCT: Angiography

2020
Optical coherence tomography angiography (OCTA) is a non-invasive technique for imaging vasculature in the eye. In the anterior segment, OCTA can produce both cross-sectional and three-dimensional images that allows for imaging of normal structures or pathology with its accompanying vasculature. Currently, imaging of the anterior segment vasculature is

Peripapillary Retinal Segmentation in OCT Angiography

Ophthalmology, 2020
Abstract Correction of automated retinal layer segmentation in the peripapillary retina led to significant differences in perfusion density measured with optical coherence tomography angiography in the retinal plexuses. Segmentation accuracy should be checked prior to interpretation.

OCT Angiography as an Interdisciplinary Diagnostic Tool for Systemic Diseases.

Klinische Monatsblätter für Augenheilkunde, 2021
In recent years, OCT angiography (OCT-A) has emerged as a well established imaging modality of the retina. This allows non-invasive visualisation of the retinal circulation at a micrometre scale in eye disorders and systemic diseases with potential ...

[OCT Angiography].

Klinische Monatsblatter fur Augenheilkunde, 2020
OCTA expands the spectrum of multimodal retinal imaging as a non-invasive procedure. Subtraction analysis of two temporally dense and identical B-scan images only show changes corresponding to the flow in the blood vessels. Freely selectable segmentation visualization of different layers of the retina, RPE, choriocapillars and choroid.
