健康成年人视神经鞘直径的影响因素分析

摘要

目的 探讨健康成年人视神经鞘直径(ONSD)的正常值范围及其影响因素.方法 选取60名健康成年体检者,记录受试对象年龄、性别、体质量指数(BMI)、血压等指标;用普通超声检测不同体位下ONSD值,分析影响ONSD的因素.结果 正常成年人的ONSD为(3.56±0.13)mm,95％可信区间为3.53～ 3.60.多因素分析结果显示,BMI是ONSD的影响因素(P＜0.05).结论 BMI可能是健康成年人ONSD值的影响因素.%Objective To explore the influencing factors and normal range of optic nerve sheath diameter (ONSD) in healthy adults.Methods Sixty healthy adults who received physical examination were enrolled.Age,gender,body mass index (BMI) and blood pressure of the subjects were recorded.ONSDs in different positions were measured by conventional B-scan ultrasonography,and the influencing factors of ONSD were analyzed.Results ONSD of healthy adults was 3.56 ± 0.13 mm,with 95 ％ confidence interval of 3.53 to 3.60.The result of multivariate analysis showed that BMI was the influencing factor of ONSD (P ＜ 0.05).Conclusion BMI might be an influencing factor of ONSD in healthy adults.
