摘要

本研究的目的是根据尼日利亚参与者的队列，评估视网膜中央动脉（CRA）内相关的多普勒参数。本研究在尼日利亚卡拉巴尔的一家医疗诊所招募并获得同意的共有 66 名参与者，时间跨度为 2019 年 8 月至 2023 年 12 月。该队列记录的诊断数据点包括空腹血糖 (FBG)（mmol/L）、CRA 收缩峰值速度 (PSV)、CRA 舒张末期速度 (EDV)、阻力指数 (RI) 和脉动指数 (PI)。数据分析的目的是提供描述性信息和相关性信息。统计显著性以 P < .05 为标准。根据右侧 CRA（右侧 PSV [20.8 ± 6.0 SD] 和右侧 EDV [5.8 ± 2.1 SD]）以及左侧 CRA（左侧 PSV [20. 6 ± 4.4 SD] 和左侧 EDV [6.2 ± 2.0 SD]）的血管流量，该队列中女性的 PSV 和 EDV 均较高。这与男性的右侧 CRA（右侧 PSV [19.6 ± 5.3 SD] 和右侧 EDV [5.2 ± 1.8 SD]）和左侧 CRA（左侧 PSV [19.2 ± 4.7 SD] 和左侧 EDV [5.3 ± 1.3 SD]）血管流量数据进行了比较。参试者的 FBG 水平与各自的多普勒参数无相关性。与左侧 CRA 相比，基于右侧 CRA 血流的多普勒参数显示出中等至弱的正相关性。在 17 至 25 岁和 26 至 34 岁的特定参与者年龄组中，右侧 CRA 中记录的 PSV 均有所不同。CRA内记录的多普勒速度可能存在与性别和年龄相关的变化，这是该组群所特有的，样本量可能会影响整个研究的统计能力。这项研究需要进行复制，并需要从更大的参与者群组中获取数据。

Sonographic Evaluation of Doppler Parameters Within the Central Retinal Artery: A Cohort Study

The objective of this study was to assess the Doppler parameters, associated within the central retinal artery (CRA), based on a cohort of Nigerian participants. A total of 66 participants were recruited and consented at a medical clinic in Calabar, Nigeria, and presented from August 2019 to December 2023. The diagnostic data points recorded on this cohort were their fasting blood glucose (FBG) (mmol/L), CRA peak systolic velocity (PSV), CRA end-diastolic velocity (EDV), the resistive index (RI), and pulsatility index (PI). The data analysis was completed to provide descriptive information, as well as correlations. The statistical significance was set at P < .05. In this cohort, the women demonstrated a higher PSV and EDV, based on the vascular flow within the right CRA (Rt. PSV [20.8 ± 6.0 SD] and Rt. EDV [5.8 ±2.1 SD]), as well as the left CRA (Lt. PSV [20. 6 ± 4.4 SD] and Lt. EDV [6.2 ± 2.0 SD]). This was compared to the men’s data taken on the vascular flow within the right CRA (Rt. PSV [19.6 ± 5.3 SD] and Rt. EDV [5.2 ± 1.8 SD]), as well as their left CRA (Lt. PSV [19.2± 4.7 SD] and Lt. EDV [5.3 ± 1.3 SD]). The participants’ FBG levels did not correlate with their respective Doppler parameters. The Doppler parameters, based on the flow within the right CRA, showed moderate to weak positive correlations compared with the left CRA. The PSV recorded in the right CRA was varied across the specific participant age groups of 17 to 25 and 26 to 34 years. Potential sex and age-related variations in the Doppler velocities, recorded within the CRA, were specific to this cohort, and the sample size may have compromised the overall study’s statistical power. A replication of this research is needed, and data from a larger cohort of participants are needed.
