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.

Distribution of Diabetic Neovascularization on Ultra-Widefield Fluorescein Angiography and on Simulated Widefield OCT Angiography.

American journal of ophthalmology-glaucoma, 2019
PURPOSE Areas of neovascularization (NV) in proliferative diabetic retinopathy (PDR) on ultrawide-field (UWF) fluorescein angiography (FA) were identified and compared with a simulated wide field (WF) swept-source OCT angiography (SS-OCTA) field of view (

OCT Angiography Imaging in Serpiginous Choroidopathy

Ophthalmology Retina, 2018
To report OCTA findings in 3 cases, 2 active and 1 inactive, of serpiginous choroidopathy (SC) and describe OCTA changes in response to treatment.Retrospective case series.We studied 6 eyes of 3 patients with SC.Retrospective case series of 3 patients with SC undergoing multimodal imaging, including OCTA.

[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.

OCT Angiography: Guidelines for Analysis and Interpretation

2020
The recent introduction of optical coherence tomography angiography (OCTA) has remarkably expanded our knowledge of the ocular vasculature. Furthermore, this imaging modality has been widely-adopted to investigate different ocular and systemic diseases.
