Thermography is an investigative tool without side effects. To our knowledge thermography has not been evaluated in the assessment of lacrimal passage inflammation and obstruction. It can give an objective assessment of presence and degree of inflammation. An infrared scanning device was used to detect surface temperatures in 29 patients with known disorders of the lacrimal drainage passage. Thermal images were compared for bilateral symmetry and against the normal thermographic appearance of the face. Acute dacryocystitis and canaliculitis showed gross hyperthermia and asymmetry. Forty-two percent of patients with a picture of chronic dacryocystitis and 40% of patients with only tearing and no clinical evidence of inflammation showed temperature elevation on the side of involvement, whereas 58% and 60% of these respective groups showed symmetrical thermal patterns, suggesting no active inflammation. In a few cases there were discrepancies between clinical assessment and objective thermographic evaluation of the degree of inflammation. The implications of our results and possible applications of thermography are discussed.
热成像技术是一种无副作用的检查工具。据我们所知，热成像技术尚未用于泪道炎症和阻塞的评估。它可以对炎症的存在和程度进行客观评估。使用红外扫描设备检测29例已知泪道引流疾病患者的表面温度。将热图像与双侧对称性以及面部正常热成像外观进行比较。急性泪囊炎和泪小管炎表现为明显的体温过高和不对称。42%的慢性泪囊炎患者和40%仅有流泪且无炎症临床证据的患者在患侧出现体温升高，而这些相应组中的58%和60%表现出对称的热模式，表明无活动性炎症。在少数情况下，临床评估与炎症程度的客观热成像评估之间存在差异。讨论了我们研究结果的意义以及热成像技术的可能应用。
