To determine the existence of differences in the retinal microcirculation of dominant and non-dominant eyes, as well as of interocular differences in macular microcirculation, using swept-source optical coherence tomography angiography (OCTA).
In total, 122 eyes of 61 individuals were enrolled in this cross-sectional study. Measurements were taken using the swept-source optical coherence tomography Triton device (Topcon Corp, Tokyo, Japan) coupled with non-invasive OCTA technology. Macular perfusion parameters were assessed, including superficial vascular complex, vascular density of the deep vascular complex, vascular density of the choriocapillaris vascular complex, superficial foveal avascular zone and deep foveal avascular zone. Ocular dominance was determined among individuals with healthy eyes using the hole-in-the-card test.
Ocular dominance was found in 68.9 % of right eyes and 31.1 % of left eyes. The mean age of the subjects was 34.45 ± 16.48 years (range: 18-73 years). We found that 16 (30.76 %) males and 22 (31.42 %) females had left-eye dominance (p > 0.05). None of the OCTA parameters differed between the eyes based on dominance (p > 0.05). Central macular thickness and sub-foveal choroidal thickness did not show significant differences (p > 0.05). When comparing interocular parameters, a significant difference was observed only in the inferior sector of the superficial vascular complex (p = 0.04).
There was no significant difference in OCTA parameters between dominant and non-dominant eyes. There was no predominant interocular difference in the measurements.
使用扫频源光相干断层扫描血管造影术(OCTA)确定主导眼和非主导眼的视网膜微循环是否存在差异,以及黄斑微循环的眼间差异。
本横断面研究共纳入 61 名个体的 122 只眼。使用扫频源光相干断层扫描仪 Triton 设备(Topcon 公司,东京,日本)结合无创性 OCTA 技术进行测量。评估了黄斑灌注参数,包括浅层血管复合体、深层血管复合体的血管密度、脉络膜毛细血管血管复合体的血管密度、浅层黄斑中心无血管区和深层黄斑中心无血管区。使用孔卡测试确定健康眼中的眼优势。
右眼的眼优势为 68.9%,左眼的眼优势为 31.1%。受试者的平均年龄为 34.45±16.48 岁(范围:18-73 岁)。我们发现 16 名(30.76%)男性和 22 名(31.42%)女性为左眼优势(p>0.05)。根据眼优势,OCTA 参数在双眼之间没有差异(p>0.05)。中央黄斑厚度和中心凹下脉络膜厚度无显著差异(p>0.05)。在比较眼间参数时,仅浅层血管复合体的下象限观察到显著差异(p=0.04)。
主导眼和非主导眼的 OCTA 参数没有显著差异。测量值没有明显的眼间优势差异。
