Relationship between the foveal avascular zone and foveal pit morphology.
PURPOSE To assess the relationship between foveal pit morphology and size of the foveal avascular zone (FAZ). METHODS Forty-two subjects were recruited. Volumetric images of the macula were obtained using spectral domain optical coherence tomography. Images of the FAZ were obtained using either a modified fundus camera or an adaptive optics scanning light ophthalmoscope. Foveal pit metrics (d...
متن کاملRetinal fixation point location in the foveal avascular zone.
The site of normal fixation is often assumed to be centered in the foveal avascular zone (FAZ). This assumed anatomic relationship is used during photocoagulation therapy as an objective guide to avoid damaging critical retinal structures on or near fixation. With laser therapy being directed closer and closer to the center of the FAZ, the accuracy with which the center of the FAZ locates the r...
متن کاملAutomated segmentation of foveal avascular zone in fundus fluorescein angiography.
PURPOSE. To describe and evaluate the performance of a computerized automated segmentation technique for use in quantification of the foveal avascular zone (FAZ). METHODS. A computerized technique for automated segmentation of the FAZ using images from fundus fluorescein angiography (FFA) was applied to 26 transit-phase images obtained from patients with various grades of diabetic retinopathy. ...
متن کاملEvaluation of the Vascular Density, the Area of Foveal Avascular Zone, and Corrected Vision in Patients with Diabetic Macular Edema after Anti-VEGF Therapy
Background and Objective: This study aimed to evaluate the changes in macular superficial and deep capillary plexus (SCP and DCP) density, Foveal Avascular Zone (FAZ) area, and visual acuity in patients with diabetic macular edema after anti-VEGF therapy. Materials and Methods: This descriptive-analytical study utilized before and after treatment design. In total, 30 eyes of 30 patients with d...
متن کاملIntrasession Repeatability and Interocular Symmetry of Foveal Avascular Zone and Retinal Vessel Density in OCT Angiography
Purpose To measure intrasession repeatability and interocular symmetry of the foveal avascular zone area (FAZA) and superficial retinal vessel density (SRVD) using AngioVue Analytics optical coherence tomography angiography (OCTA). Methods Fifty healthy individuals were prospectively enrolled. OCTA scans (3 × 3 and 6 × 6 mm) were acquired twice in right and once in left eyes. FAZA (with and w...
