This study aimed to compare the dominant and non-dominant eyes of healthy individuals in terms of CT and CVI values to assess the effect of ocular dominance on choroidal morphology. Three hundred eyes of 150 individuals were included in this study. All patients underwent routine ophthalmological examinations and hole-in-the-card tests to determine the dominant eye. EDI-OCT was used to obtain choroidal images. Choroidal thickness (CT) was measured at three points on the choroid including the subfoveal region (subfoveal choroidal thickness (SFCT)), 1500 μm nasal (NCT) and temporal (TCT) to the fovea. Choroidal vascularity index (CVI), total choroidal area (TCA), luminal area (LA), and stromal area (SA) were measured at fovea-centered choroidal area by image binarization via Image J software. While 93(%62) participants were right-eyed, 57(%38) participants were left-eyed. We could not detect any difference in SFCT, NCT, TCT, TCA, LA, SA, and CVI measurements between the dominant and the non-dominant eyes. (> 0.05 for all). We could not detect any effect of ocular dominance on choroidal structures. These results also support the use of randomized ocular data regardless of which eye is dominant when investigating CVI and CT in scientific research.
本研究旨在比较健康个体的主导眼和非主导眼的 CT 和 CVI 值，以评估眼优势对脉络膜形态的影响。本研究纳入了 150 名个体的 300 只眼。所有患者均接受了常规眼科检查和孔卡测试以确定主导眼。采用 EDI-OCT 获得脉络膜图像。在脉络膜的三个点测量脉络膜厚度（CT），包括黄斑下区域（黄斑下脉络膜厚度（SFCT））、黄斑 1500μm 鼻侧（NCT）和颞侧（TCT）。通过 Image J 软件对以黄斑为中心的脉络膜区域进行图像二值化，测量脉络膜血管指数（CVI）、总脉络膜面积（TCA）、管腔面积（LA）和基质面积（SA）。93%（62 名）参与者为右眼，57%（38 名）参与者为左眼。我们未发现主导眼和非主导眼之间的 SFCT、NCT、TCT、TCA、LA、SA 和 CVI 测量值存在差异（所有 P 值均>0.05）。我们未发现眼优势对脉络膜结构有任何影响。这些结果也支持在科学研究中使用随机的眼部数据，而无需考虑哪只眼是主导眼，以研究 CVI 和 CT。
