Popis: To determine the area of the surface foveal avascular zone (FAZ) in children with posterior microphthalmos (PM), high hyperopia, and normal eyes using optical coherence tomography (OCT) and OCT angiography (OCTA).Thirty-six children were studied including 6 cases 12 eyes of PM (mean age 9.5 ± 5.2 years), 15 cases 30 eyes of high hyperopia (6.9 ± 1.5 years), and 15 cases 30 eyes of healthy individuals (8.7 ± 1.7 years). The B- and C-scan images in all children were recorded by OCT and OCTA with a scanning area of 3.0 × 3.0 mm centered on the fovea. All images were corrected for axial length differences, and the area of the FAZ surface and central macular thickness (CMT) was measured manually and compared.The area of FAZ in the PM group was 0.007 ± 0.003 mmThese findings indicate that patients with PM have a hypoplastic macular region, which must be considered in any treatment of these eyes.
