本研究的目的是通过同时比较眼球跟踪(ET)参数和脑血氧饱和度来评估轻度创伤性脑损伤(MTBI)患者的眼动协同效应与脑氧状态的关系。这项非随机单中心前瞻性研究包括77例mTBI患者(平均年龄36.3±4.8岁，男性48例，女性29例，GCS中位数13.7±0.7)。采用脑氧仪检测额叶极区血氧饱和度(SctO2)。同时使用眼镜仪测量眼球运动。计算的参数为：眼球垂直和水平角速度(AV)；左垂直速度(LVS)；右垂直速度(RVS)；左水平速度(LHS)；右水平速度(RHS)。计算垂直眼和水平眼的版本指数(Version Index，VX)，计算右眼和左眼对应的视听度之间的Pearson相关系数。重要性被预先设定为p<；0.05。FLP中SctO2为62%~79%。左侧FLP和右侧FLP的SctO2平均值分别为69.26±6.96%和70.25±7.58%(p=0.40)。对眼球跟踪数据的总体分析显示，凝视参数如下：左眼轴-0.327±0.263拉德/秒；左眼-0.201±0.164拉德/秒；右眼-0.361±0.269拉德/秒；右眼-0.197±0.124拉德/秒。计算垂直版本指数(VVX)为0.80±0.12。计算的水平版本指数(HVx)为0.82±0.11。VVx和Hvx与FLP中SctO2水平呈正相关(p=0.038；r=0.235；p=0.048；r=0.218，分别为p=0.035；r=0.241；p=0.039；r=0.235)。Vvx和Hvx与mTBI中FLP(p<；0.01)中的SctO2水平相关。SctO2水平与眼球垂直和水平AV之间无显著相关性。眼球跟踪可以帮助量化mTBI后眼睛共轭损害的严重程度，以及探索脑氧状态障碍对这一过程的贡献。
The aim of this study was to assess the relationship between oculomotor synergies and brain oxygen status at mild traumatic brain injury (mTBI) using simultaneous comparison of eye-tracking (ET) parameters and cerebral oxygen saturation. This non-randomised single-centre prospective study included 77 patients with mTBI (mean age was 36.3 ± 4.8 years, 48 men, 29 women, median GCS 13.7 ± 0.7). Cerebral oximetry was used to detect oxygen saturation level (SctO2) in the frontal lobe pole (FLP) region. Eye movements were measured simultaneously using the EyeTracker. Calculated parameters were: vertical and horizontal angular eyeball velocity (AV); left vertical speed (LVS); right vertical speed (RVS); left horizontal speed (LHS); and right horizontal speed (RHS). The indices of vertical and horizontal eye version (version index, Vx) were calculated as the Pearson correlation coefficient between the corresponding AV of the right and left eyes. Significance was pre-set to p < 0.05. SctO2 in the FLP varied from 62% to 79%. The average SctO2 values were 69.26 ± 6.96% over the left FLP and 70.25 ± 7.58% over the right FLP (p = 0.40). The total analysis of the eye-tracking data revealed the following values of gaze parameters: LVS – 0.327 ± 0.263 rad/sec; LHS – 0.201 ± 0.164 rad/sec; RVS – 0.361 ± 0.269 rad/sec; and RHS – 0.197 ± 0.124 rad/sec. The calculated vertical version index (VVx) was 0.80 ± 0.12. The calculated horizontal version index (HVx) was 0.82 ± 0.11. The VVx and HVx were correlated with SctO2 levels in the FLP (p = 0.038; r = 0.235; p = 0.048; r = 0.218, respectively p = 0.035; r = 0.241; p = 0.039; r = 0.235, respectively). VVx and HVx correlate with the SctO2 level in the FLP (p < 0.01) in mTBI. No significant correlation was detected between the level of the SctO2 level and vertical and horizontal AV of the eyeballs. Eye tracking can help quantify the severity of ocular conjugation impairments after mTBI, as well as explore the contribution that cerebral oxygen status disorders make to this process.
