Infrared thermography (IRT) is a well-known imaging technique that provides a non-invasive displaying of the ocular surface temperature distribution. Currently, compact smartphone-based IRT devices, as well as special software for processing thermal images, have become available. The study aimed to determine the possible use of smartphone-based IRT devices for real-time ocular surface thermal imaging. This study involved 32 healthy individuals (64 eyes); 10 patients (10 eyes) with proliferative diabetic retinopathy (PDR) and absolute glaucoma; 10 patients (10 eyes) with PDR, who underwent vitreoretinal surgery. In all cases, simultaneous ocular surface IRT of both eyes was performed. In healthy individuals, the ocular surface temperature (OST) averaged 34.6 ± 0.8 °C and did not differ substantially between the paired eyes, in different age groups, and after pupil dilation. In our study, high intraocular pressure was accompanied by a decrease in OST in all cases. After vitreoretinal surgery in cases with confirmed subclinical inflammation, the OST was higher than the baseline and differed from that of the paired eye by more than 1.0 °C. These results highlight that smartphone-based IRT imaging could be useful for the non-invasive detection of OST asymmetry between paired eyes due to increased intraocular pressure or subclinical inflammation.
红外热成像（IRT）是一种众所周知的成像技术，可提供眼部表面温度分布的非侵入性显示。目前，基于紧凑智能手机的 IRT 设备以及用于处理热图像的特殊软件已经问世。本研究旨在确定基于智能手机的 IRT 设备在实时眼部表面热成像中的可能用途。本研究涉及 32 名健康个体（64 只眼睛）；10 名患有增生性糖尿病视网膜病变（PDR）和绝对青光眼的患者（10 只眼睛）；10 名接受玻璃体视网膜手术的 PDR 患者（10 只眼睛）。在所有情况下，均对双眼同时进行眼部表面 IRT。在健康个体中，眼部表面温度（OST）平均为 34.6±0.8°C，在不同年龄组和瞳孔扩张后，双眼之间的 OST 没有明显差异。在我们的研究中，高眼压伴随着所有情况下 OST 的降低。在经证实存在亚临床炎症的病例中进行玻璃体视网膜手术后，OST 高于基线，与配对眼相差超过 1.0°C。这些结果表明，基于智能手机的 IRT 成像可能有助于非侵入性检测由于眼内压升高或亚临床炎症引起的双眼之间的 OST 不对称。
