摘　　要：目的:应用扫频源光学相干断层扫描血管成像(SS-OCTA)观察不同屈光状态下儿童的脉络膜厚度变化。方法:59例(118只眼) 6~13岁的儿童受试者作为研究对象,分为远视组、正视组和近视组。分别测量受试者的眼部参数包括屈光度(等效球镜,SE)、眼轴长度(AL)、和黄斑区下脉络膜厚度(CT)、黄斑区中心凹下脉络膜厚度(SFCT)。CT是使用ETDRS网格自动生成的以黄斑中心凹为中心的9个区域的区域下脉络膜厚度,SFCT是黄斑区中心凹下点的脉络膜厚度。结果:远视、正视和近视组三组受试者屈光度对比,差异有统计学意义(P Objective: Sweep-source optical coherence tomography angiography (SS-OCTA) was used to observe the choroidal thickness changes in children with different refractive conditions. Method: Fifty-nine (118 eyes) pediatric subjects aged 6~13 years were divided into hyperopic group, emmetropia group and myopia group. The ocular parameters included refraction (equivalent, SE), axial length (AL), and subchoroidal thickness (CT), and subfoveal choroidal thickness (SFCT). The CT is the regional inferior choroidal thickness of nine sectors centered on the macular fovea and automatically generated using an ETDRS grid., and the SFCT is the choroidal thickness at the subfoveal point of the macular region. Results: Significant differences were found between the three subjects of hyperopia, emmetropia and myopia groups (P < 0.001). The AL became longer as the refraction progressed from hyperopia to myopia, and the AL was significantly different between the three groups (P < 0.001). Choroidal thickness was significantly different between the three groups, with the thinnest choroidal thickness in the myopic group, followed by emmetropia, and the thickest in the hyperopia group (P < 0.001). The distribution of choroidal thickness in the ETDRS grid was consistent, centered on the macular fovea, the inner quadrant CT was higher than the outer quadrant CT, the CT in the nasal quadrant was s
