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 15 healthy young adults were evaluated. The mean horizontal FAZ diameter of superficial vascular plexus was 661.166 ± 119.99 microns and mean vertical FAZ diameter was 660.033 ± 96.169 microns (P = 0.9442). The mean horizontal FAZ diameter of deep vascular plexus was 1011.2 ± 154.526 microns and the mean vertical FAZ diameter of deep vascular plexus was 818.033 ± 102.108 microns. There was no difference between the contralateral eyes of subjects in FAZ diameter of both superficial and deep capillary plexuses.
CONCLUSION
The mean diametric size of FAZ in superficial capillary plexus is 660.599 ± 0.801 microns and deep capillary plexus is 914.616 ± 136.589 microns. There was no significant difference with the contralateral eyes.
背景
本研究的目的是使用光学相干断层扫描血管造影术（OCT）测量健康年轻成年人双眼的黄斑无血管区（FAZ）直径大小。
方法
一项测量健康年轻成年人黄斑无血管区的横断面研究。受试者双眼使用蔡司AngioPlex OCT血管造影术进行OCT血管造影。
结果
对15名健康年轻成年人的30只眼睛进行了评估。浅表血管丛的平均水平FAZ直径为661.166±119.99微米，平均垂直FAZ直径为660.033±96.169微米（P = 0.9442）。深部血管丛的平均水平FAZ直径为1011.2±154.526微米，深部血管丛的平均垂直FAZ直径为818.033±102.108微米。受试者双眼在浅表和深部毛细血管丛的FAZ直径方面没有差异。
结论
浅表毛细血管丛中FAZ的平均直径大小为660.599±0.801微米，深部毛细血管丛为914.616±136.589微米。与对侧眼相比无显著差异。
