研究目的: |
1.主要目的 本研究旨在通过一项前瞻性干预性临床研究,招募 18-28岁低、中、高度近视相关眼底改变的年轻成人患者,利用超广域 SS-OCT/OCTA评估七叶洋地黄双苷滴眼液对眼部血流动力学及相关结构参数的短期影响。通过将药物干预与无创影像学技术相结合,探索其在改善眼部微循环、尤其是脉络膜与视网膜血流方面的潜在临床价值,并为后续青少年近视相关眼底改变防控研究提供可靠的技术路径与参数基线。 2.次要目的 (1)比较不同近视程度合并眼底改变人群在七叶洋地黄双苷滴眼液干预前后,眼部血流动力学指标(包括中央凹下脉络膜厚度 SFCT、脉络膜血管指数 CVI、脉络膜毛细血管丛灌注密度、黄斑区视网膜血管密度、前节血流动力学等)及相关结构参数的变化差异; (2)探讨七叶洋地黄双苷滴眼液对近视相关眼底改变年轻成人患者干预前后视盘相关结构(如视盘旁萎缩弧)的变化及其与血流动力学指标的相关性; (3)探讨不同个体基线特征(如性别、虹膜色素类型、眼轴长度、基线 SFCT及前节结构参数等)对干预效果的影响,筛选潜在的治疗响应预测因子; (4)验证超广域 SS-OCT/OCTA 在近视相关眼底改变患者眼部血流动力学定量分析中的可行性与稳定性,为后续青少年近视相关眼底改变防控研究提供技术路径和参数基线。 |

Objectives of Study: |
1. Main objective This study aims to conduct a prospective interventional clinical research to recruit young adults aged 18-28 with low, moderate, and high myopia-related fundus changes. Using ultra-widefield SS-OCT/OCTA, the short-term effects of the seven-leaf digitalis dianide eye drops on ocular hemodynamics and related structural parameters will be evaluated. By combining drug intervention with non-invasive imaging techniques, the potential clinical value of this drug in improving ocular microcirculation, especially in the choroid and retina blood flow, will be explored, and a reliable technical path and parameter baseline will be provided for subsequent research on the prevention and control of myopia-related fundus changes in adolescents. 2. Secondary objectives (1) To compare the differences in ocular hemodynamic indicators (including subfoveal choroidal thickness SFCT, choroidal vascular index CVI, choroidal capillary bed perfusion density, macular retinal vascular density, anterior segment hemodynamics, etc.) and related structural parameters before and after intervention with the seven-leaf digitalis dianide eye drops in populations with different degrees of myopia and fundus changes; (2) To explore the changes in optic disc-related structures (such as peripapillary atrophy arcs) in young adults with myopia-related fundus changes before and after intervention with the seven-leaf digitalis dianide eye drops and their correlation with hemodynamic indicators; (3) To explore the influence of different baseline characteristics (such as gender, iris pigment type, axial length, baseline SFCT and anterior segment structural parameters, etc.) on the intervention effect, and to screen potential predictors of treatment response; (4) To verify the feasibility and stability of ultra-widefield SS-OCT/OCTA in the quantitative analysis of ocular hemodynamics in patients with myopia-related fundus changes, and to provide a technical path and parameter baseline for subsequent research on the prevention and control of myopia-related fundus changes in adolescents. |
