摘要： 目的运用Sirius系统对准分子术前患者的前房参数以及角膜中央厚度进行检测,探讨上述因素之间的相关性、规律性,以及性别、年龄对其的影响。方法分组:对210例近视眼患者(420只眼)根据屈光度分为低度近视组,中度近视组、高度近视组。采用Sirius系统对三组检测眼进行角膜中央厚度、中央前房深度、前房容积、颞侧及鼻侧房角宽度进行测量,并采用相关性分析,单因素方差分析对检测数据进行统计学分析。结果屈光度数绝对值与颞侧房角呈正相关,中央前房深度与前房容积呈正相关、与颞侧及鼻侧房角宽度均呈正相关。颞侧与鼻侧房角宽度亦呈正相关。年龄与中央前房深度呈负相关。不同屈光度度数组别之间颞侧房角宽度存在统计学差异性。男性中央前房深度及颞侧房角宽度明显大于女性。结论 Sirius系统可以作为一种便捷、准确且无创的角膜厚度及前房参数的测量工具。近视眼患者的前房参数与屈光度数、中央角膜厚度、年龄、性别存在一定的相关性性、规律性。

Abstract: Objective To analyze the correlation and principle of anterior chamber parameter and central cornea thickness, the influence by the sexual and age in the pre-operative patients with excimer laser by using Sirius system. Methods 210 patients (410 eyes)were divided into 3 groups based on refractive status:low myopia,moderate myopia and high myopia.Central cornea thickness(CCT),anterior chamber depth(ACD),anterior chamber volume(ACV),temporal(T) and nasal anterior chamber width(N) were measured by Sirius system. The results are analyzed by correlation and one-way anova of statistics. Results A positive correlation was found in the absolute value of diopter and temporal anterior chamber width, the anterior chamber depth(ACD) and anterior chamber volume(ACV), temporal(T) and nasal anterior chamber width(N), and also in the temporal and nasal anterior chamber width. There was a negative correlation between age and temporal and nasal anterior chamber width. There were significantly statistics differences in the temporal anterior chamber width between different diopter groups. The anterior chamber depth(ACD) and temporal anterior chamber width of males were obvious deeper than females. Conclusion The Sirius system may be used as a convenient, precise and noninvasive technique in cornea thickness and anterior chamber parameter measurement. There is a definite correlation and principle in the anterior chamber parameter and diopter, central cornea thickness, age and sexual.
