Abstract

Purpose : To describe the temperature of the ocular surface by infrared thermography imaging in a healthy adult population in Bogotá, Colombia.

Methods : A cross-sectional study was carried out. All subjects underwent complete ophthalmological examination. Infrared thermography images were acquired using the FLIR ONE thermal camera. Ambiental temperature and humidity were constantly monitored and maintained within an average of 21°C + 2 and 55 % +2. Body temperature was measured previously in all subjects. The infrared thermal images were read and divided into four quadrants termed as: Superior Temporal (ST), Superior Nasal (SN), Inferior Temporal (IT) and Inferior Nasal (IN). The mean and median statistical measures were calculated in order to determine differences among the quadrants. The analysis of the data was done with SPSS 21.0 version

Results : 28 eyes were included (15 subjects) that met the inclusion criteria, 62% were women with a median age of 31 years (IQR 8). Median body temperature was 36, 40 °C (IQR 0.1). The superior temporal quadrant had a median temperature of 38.46 °C (IQR 0.97), the superior nasal quadrant had a median temperature of 37,77°C (IQR 1.63), the inferior temporal quadrant had a median temperature of 38.50°C (IQR 0.71) and the inferior nasal quadrant had a median temperature of 38.53° C (IQR 0.91).

Conclusions : Thermal imaging was successfully applied for evaluation of the ocular surface temperature in adult healthy subjects, and it was correlated with body temperature. A lower body temperature was reported when compared to ocular surface temperature. The inferior nasal quadrant showed a higher temperature that the others. This could be correlated with the findings reported by Fellman et al. where episcleral flow in the human eye is largely segmented, favored inferonasall
