| 摘 要： | 目的 检测青年近视患者的眼球运动参数，比较不同程度近视组眼动参数差异，分析眼动参数与眼轴长度、等效球镜度的相关性。 方法 招募91例青年近视患者，基于等效球镜度将研究对象分为轻度、中度和高度近视组。收集研究对象的年龄、性别资料，完成基础临床检查，采用眼动仪检测研究对象的双眼注视、反射性扫视和反向扫视功能。采用单因素方差分析或秩和检验比较3组近视患者的一般资料和眼球运动参数，采用Pearson或Spearman相关性分析注视区95%二维椭圆面积（BCEA）、扫视运动各项参数与眼轴长度、等效球镜度的相关性。 结果 轻度、中度和高度近视组的95%BCEA分别为2.08 （0.54，14.69） deg2、4.99（0.94，49.22） deg2、5.79 （2.18，64.91） deg2。3组研究对象的95%BCEA差异有统计学意义（P=0.029），轻度近视组的95%BCEA比高度近视组更小（P=0.01）。3组研究对象的各项扫视参数差异无统计学意义（P>0.05）。95%BCEA与眼轴长度呈正相关（r=0.342， P=0.001）；95%BCEA与等效球镜度呈负相关（r=?0.322，P=0.002）；扫视运动各项参数与眼轴长度、等效球镜度均无相关性（P>0.05）。 结论 青年近视患者眼轴越长、近视程度越高，注视稳定性越差。高度近视患者的注视稳定性低于轻度近视患者。不同程度近视患者的扫视运动参数无差异。

| Abstract: | Objective To measure the parameters of eye movement of young adult patients of myopia, to compare the differences in the parameters of patient groups with varied degrees of myopia, and to analyze the correlation between eye movement parameters and axial length (AL) and spherical equivalent refraction (SER). Methods A total of 91 young adult patients of myopia were recruited. The subjects were divided into three groups of low, moderate, and high myopia according to their SER. Information on the subjects’ age and sex was collected and general clinical examination was completed. The subjects’ binocular fixation, reflexive saccade, and antisaccade were measured with eye tracker. One-way ANOVA or Kruskal-wallis test was used to compare the general data and eye movement parameters of the three groups of myopic patients. Pearson or Spearman correlation analysis was used to analyze AL and SER’s correlation with 95% bivariate contour ellipse area (BCEA) and saccadic parameters. Results The 95% BCEA for mild, moderate, and high myopia groups were 2.08 (0.54, 14.69) deg2, 4.99 (0.94, 49.22) deg2, and 5.79 (2.18, 64.91) deg2, respectively. There was significant difference between the 95% BCEA of the three groups (P=0.029). The 95% BCEA of the mild myopia group was significantly smaller than that of the high myopia group (P=0.01). There were no significant differences in saccadic parameters among the three groups (P>0.05). There was a significant positive correlation between 95% BCEA and AL (r=0.342, P=0.001). There was a significant negative correlation between 95% BCEA and SER (r=?0.322, P=0.002). There was no significant correlation between the parameters of saccadic movement and the AL or SER (P>0.05). Conclusion For young adult myopic patients, the longer the AL is, the higher the degree of the myopia and the worse the fixation stability becomes. The fixation stability of patients with high myopia was significantly worse than that of patients with mild myopia. There was no significant difference in saccadic parameters in patients with different degrees of myopia. |
