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.

Artificial intelligence in OCT angiography

Progress in Retinal and Eye Research, 2021
Optical coherence tomographic angiography (OCTA) is a non-invasive imaging modality that provides three-dimensional, information-rich vascular images. With numerous studies demonstrating unique capabilities in biomarker quantification, diagnosis, and monitoring, OCTA technology has seen rapid adoption in research and clinical settings.

A Review of OCT Angiography in Glaucoma

Seminars in Ophthalmology, 2019
There is growing evidence that vascular dysfunction plays a role in the pathogenesis of glaucoma. The details of this relationship have remained elusive partially due to limitations in our ability to assess blood flow in the optic nerve. Optical coherence tomography angiography (OCTA) has emerged as a promising new technology well positioned to become ...

Technische Grundlagen der OCT-Angiographie

Der Ophthalmologe, 2015
Optical coherence tomography angiography (OCT-A) is a new diagnostic non-invasive method by which the vascular structures of the retina and choroid can be visualized three-dimensionally without need for using fluorescence dyes. The technology of OCT-A is an advancement of the OCT.

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.

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
