摘　　要：目的利用非接触红外测温仪对大样本量健康人群眼球表面角膜温度(TOC)进行测量,确立其正常值范围。方法采用大样本单中心随机抽样方法,在上海市浦东新区体检人群中随机抽取健康志愿者作为受试者。于(26±2)℃的环境温度及(60±5)%的相对湿度条件下,采用非接触红外测温仪测量所有受试者右眼瞬目后即刻眼球表面TOC。结果经随机抽样和筛选共计入选3288名受试者。其中男性1978名,女性1310名;年龄≤15岁者396名,15岁<年龄≤30岁者942名,30岁<年龄≤50岁者1482名,年龄>50岁者468名。受试人群平均眼球表面TOC为(32.06±1.24)℃。各年龄段受试者眼球表面TOC呈现随年龄增长而上升的趋势。男性和女性受试者平均眼球表面TOC分别为(32.26±1.11)℃和(31.75±1.36)℃,两者间比较差异有统计学意义(P<0.01),但分别与受试人群平均眼球表面TOC比较差异均无统计学意义(P>0.05)。结论在环境温度为(26±2)℃及相对湿度为(60±5)%的条件下,临床上可将(32.06±1.24)℃作为非接触红外测温仪测量眼球表面TOC的正常值范围,并建议适时考虑可能存在的性别差异。Objective To measure the temperature of cornea （TOC） on ocular surface of healthy people with non-contact infrared thermometer, and determine the reference range. Methods Large sample single center random sampling was adopted to select healthy volunteers from medical examinees of Pudong New District of Shanghai. With environment temperature of （26±2） ℃ and relative humidity of （60±5）%, non-contact infrared thermometer was used to measure TOC on ocular surface of right eyes after blinking. Results A total of 3 288 subjects were enrolled after random sampling and screening, with 1 978 males and 1 310 females. Three hundred and ninety-six subjects aged no more than 15 years, 942 aged between 15 and 30 years, 1 482 aged between 30 and 50 years, and 468 aged more than 50 years. TOC on ocular surface of total sample was （32.06±1.24）℃. TOC on ocular surface exhibited an increased tendency with age stages. There were significant differences in TOC of ocular surface between males and females [（32.26±1.11）℃ vs （31.75±1.36）℃, P〈0.01]. However, there was no significant difference in TOC of ocular surface between males and total sample and between females and total sample （P〉0.05）. Conclusion With environment temperature of （26±2）℃ and relative humidity of （60±5）%, （32.06±1.24） ℃ may serve as the normal range of TOC on ocular surface measured by non-contact infrared thermometer in clinics, and there may exist differences between males and females.
