The Association Between the Foveal Avascular Zone and Retinal Thickness [PDF]
Investigative Ophthalmology & Visual Science, 2014 To investigate the association between the size and shape of the foveal avascular zone and retinal thickness in healthy subjects.In vivo imaging of the foveal microvasculature was performed on 32 subjects by using an adaptive optics scanning laser ophthalmoscope (AOSLO). Motion contrast maps of the AOSLO images were used to generate a montage revealing

A Reliable Criterion for the Correct Delimitation of the Foveal Avascular Zone in Diabetic Patients. [PDF]
J Pers Med, 2023 Background: Manual segmentation of the Foveal Avascular Zone (FAZ) has a high level of variability. Research into retinas needs coherent segmentation sets with low variability. Methods: Retinal optical coherence tomography angiography (OCTA) images from type-1 diabetes mellitus (DM1), type-2 diabetes mellitus (DM2) and healthy patients were included ...

Automatic segmentation of the foveal avascular zone in ophthalmological OCT-A images [PDF]
PLOS ONE, 2019 Angiography by Optical Coherence Tomography is a non-invasive retinal imaging modality of recent appearance that allows the visualization of the vascular structure at predefined depths based on the detection of the blood movement. OCT-A images constitute a suitable scenario to analyse the retinal vascular properties of regions of interest, measuring ...

The Size of the Foveal Avascular Zone Is Associated with Foveal Thickness and Structure in Premature Children [PDF]
Journal of Ophthalmology, 2019 Purpose. To investigate the foveal avascular zone (FAZ) in the eyes of patients with a history of retinopathy of prematurity (ROP) using optical coherence tomography angiography (OCTA) and to identify associated clinical factors. Patients and methods. Overall, 14 children with a history of laser treatment for ROP, 17 children born prematurely without a
