目的:以眼压为指征来明确眼部的交感神经活性的非对称性。方法:在回顾性横断面研究中,对150名新生儿、80名年轻人和159名老年人表面麻醉后使用Tono-pen笔式眼压计测量眼压。结果:在新生儿的眼压右眼16.16mmHg、左眼15.79mmHg,在年轻人的眼压右眼是15.04mmHg、左眼14.71mmHg,在老年人的眼压右眼是15.16mmHg、左眼15.03mmHg。右眼眼压具有统计学差异的是新生儿(P=0.03)和年轻人(P=0.02),在老年人是没有统计学差异(P=0.26)。右眼更高的眼压表明其交感神经活性的降低。结论:我们猜测在双侧器官存在的交感神经活性非对称性是有助于建立身体器官的优势模式。

AIM:To determine the asymmetry in the sympathetic activity in the eyes as indicated by intraocular pressure(IOP). ·METHODS:In a prospective cross sectional study,the IOP in 150 newborns,80 young adults and 159 old people was measured with Tono-Pen under topical anaesthesia. ·RESULTS:The mean IOP in the newborns was 16.16mmHg in right eye and 15.79mmHg in left eye; in young adults 15.04mmHg in right eye and 14.71 in left eye; in old people 15.16 in right eye and 15.03 in left eye. A statistically significant higher IOP was noted in the right eye in the newborns (P=0.03) and in young adults (P=0.02),but not in the old people (P=0.26). The higher IOP in the right eye indicates the lowered sympathetic activity in that eye.·CONCLUSION:We hypothesize that the sympathetic asymmetry in the bilaterally placed organs helps to establish the dominant pattern of the organ in the body.
