Several studies suggest that the temperature of the inner canthus of the eye (T(ca)), determined with infrared thermal imaging, is an appropriate method for core temperature estimation in mass screening of fever. However, these studies used the error prone tympanic temperature as a reference. Therefore, we compared T(ca) to oesophageal temperature (T(es)) as gold standard in 10 subjects during four conditions: rest, exercise, recovery and passive heating. T(ca) and T(es) differed significantly during all conditions (mean ΔT(es) - T(ca) 1.80 ± 0.89°C) and their relationship was inconsistent between conditions. Also within the rest condition alone, intersubject variability was too large for a reliable estimation of core temperature. This poses doubts on the use of T(ca) as a technique for core temperature estimation, although generalization of these results to fever detection should be verified experimentally using febrile patients.
多项研究表明，通过红外热成像测定的眼内眦温度（T(ca)）是大规模发热筛查中估计核心温度的一种合适方法。然而，这些研究将容易出错的鼓膜温度作为参考。因此，我们在10名受试者处于休息、运动、恢复和被动加热这四种状态下，将T(ca)与作为金标准的食管温度（T(es)）进行了比较。在所有状态下，T(ca)和T(es)均存在显著差异（平均ΔT(es)−T(ca)为1.80±0.89°C），且它们在不同状态下的关系并不一致。仅在休息状态下，受试者之间的变异性就太大，无法可靠地估计核心温度。这对将T(ca)用作估计核心温度的技术提出了质疑，尽管这些结果推广到发热检测还应通过发热患者进行实验验证。
