Clinical utility of OCTA

Canadian Eye Care Today, 2022
Optical coherence tomography angiography (OCTA) is a novel technology that can produce images of blood flow with unprecedented resolution of all the vascular layers of the retina and choroid in a rapid, non-invasive fashion. The technology dates back to 2005, when researchers demonstrated that blood flow could be visualized using swept-source OCT (SS ...

Deep-OCTA: Ensemble Deep Learning Approaches for Diabetic Retinopathy Analysis on OCTA Images

, 2023
The ultra-wide optical coherence tomography angiography (OCTA) has become an important imaging modality in diabetic retinopathy (DR) diagnosis. However, there are few researches focusing on automatic DR analysis using ultra-wide OCTA. In this paper, we present novel and practical deep-learning solutions based on ultra-wide OCTA for the Diabetic ...

Sam-Octa: Prompting Segment-Anything for Octa Image Segmentation

Biomedical Signal Processing and Control
Segmenting specific targets or biomarkers is necessary to analyze optical coherence tomography angiography (OCTA) images. Previous methods typically segment all the targets in an OCTA sample, such as retinal vessels (RVs). Although these methods perform well in accuracy and precision, OCTA analyses often focusing local information within the images ...
