Diametric measurement of foveal avascular zone in healthy young adults using optical coherence tomography angiography
BACKGROUND The objective of this study is to measure the diameter size of foveal avascular zone (FAZ) in both eyes of healthy young adults using optical coherence tomography (OCT) angiography. METHODS A cross sectional study to measure the foveal avascular zone in healthy young adults. Subjects underwent OCT angiography using Zeiss AngioPlex OCT angiography in both eyes. RESULTS 30 eyes of ...
متن کاملAssessing the Accuracy of Foveal Avascular Zone Measurements Using Optical Coherence Tomography Angiography: Segmentation and Scaling
PURPOSE The foveal avascular zone (FAZ) is altered in numerous diseases. We assessed factors (axial length, segmentation method, age, sex) impacting FAZ measurements from optical coherence tomography (OCT) angiography images. METHODS We recruited 116 Caucasian subjects without ocular disease, and acquired two 3 × 3 mm AngioVue scans per each right eye (232 total scans). In images of the super...
متن کاملThe quantitative measurements of foveal avascular zone using optical coherence tomography angiography in normal volunteers
Purpose To provide normative data of foveal avascular zone (FAZ) and thickness. Methods In this cross-sectional study both eyes of each normal subject were scanned with optical coherence tomography angiography (OCTA) for foveal superficial and deep avascular zone (FAZ) and central foveal thickness (CFT) and parafoveal thickness (PFT). Results Out of a total of 224 eyes of 112 volunteers wit...
متن کاملQuantitative optical coherence tomography angiography of macular vascular structure and foveal avascular zone in glaucoma
OBJECTIVE The study aimed to evaluate the quantitative characteristics of the macular vessel density (VD) and foveal avascular zone (FAZ) in glaucoma using optical coherence tomography angiography (OCT-A). DESIGN Cross-sectional, age- and sex-matched case-control study. METHODS Fifty-two eyes of 52 patients with primary open angle glaucoma and 52 eyes from 52 healthy participants were recru...
متن کاملFoveal Avascular Zone in Normal Tension Glaucoma Measured by Optical Coherence Tomography Angiography
Aim To measure diameter of foveal avascular zone (FAZ), FAZ area, and vessel density using Optical Coherence Tomography Angiography (OCT-A) in patients with normal tension glaucoma (NTG) and to establish the possible role of OCT-A in diagnosis and follow-up of patients with NTG. Methods Twenty-one eyes of 21 patients with NTG and 30 eyes of 30 healthy subjects underwent complete ophthalmic ex...
