Methods: Forty healthy individuals (80 eyes) were enrolled to the study. Participants underwent a detailed ophthalmologic examination and medical history review for excluding any ocular and systemic diseases. The measurements of the central corneal temperature were performed in a room having constant temperature, humidity, and brightness levels. To avoid any variability, all the temperature measurements were performed in the same examination room by a single examiner. The temperature was measured with a handheld infrared skin thermometer (MEDISANA, FTN) from the corneal surface. The same instrument was also used to measure the subjects' body temperature. Moreover, the subjects underwent the corneal temperature measurement by a noncontact videothermography device (Optris PI 450; Optris GmbH). Results: The male to female ratio was 19:21 among the subjects. The mean age was 25.14.7 years. The mean body temperature was 36.93 +/- 0.33 degrees C. The mean corneal temperatures measured by the handheld infrared skin thermometer and the ocular videothermography device were 36.94 +/- 0.28 degrees C and 35.61 +/- 0.61 degrees C, respectively (P<0.01). The mean temperature difference was 1.34 +/- 0.57 degrees C, with a 95% confidence interval. There was a moderate correlation between the corneal temperatures measured by the 2 devices in the right, the left eyes, and both eyes, respectively (P=0.450, 0.539, 0.490). Conclusions: Handheld infrared skin thermometers can be used for the evaluation of the corneal temperature. These devices may provide a simple, practical, and cheaper way to detect the corneal temperature, and the widely performed corneal temperature measurements may afford us to understand the temperature variability in numerous ocular conditions in a better way.en10.1097/ICL.0000000000000174info:eu-repo/semantics/closedAccessCorneal temperatureHandheld infrared skin thermometerVideothermography deviceArticle423202205WOS:00037594160001126219077Q3
