Body temperature reflects the animal health and/or disease conditions. During clinical examination, temperature measurement is a basic step in veterinary medicine. The conventional method used is the rectal thermometry, particularly stressful in some subjects, especially for cats. A less stressful alternative method, such as infrared thermal imaging camera, is used in various fields of medicine for diagnosis, prognosis and correct therapeutic approaches. To evaluate the usefulness of infrared thermal imaging for the assessment of ocular temperature, twenty cats of different breeds (European, Siamese and Persian, 4-6 years old, mean body weight 4.3 ± 0.30 Kg) were enrolled in the study. In order to evaluate the applicability of the ocular temperature assessment through thermal imaging as a tool for measuring the animal's body temperature, the obtained values were compared with the rectal temperature values recorded in each cat by means of a digital thermo-camera. There were no differences between left and right eye; and a difference of about 1.19 °C between the ocular and rectal temperature value was recorded (p < 0.0001). Rectal and ocular temperatures were positively correlated (p < 0.0001; r = 0.93). In conclusion, we show that ocular temperature is an alternative method for body temperature measurement that can be used in clinical evaluation of cats, especially in cases where rectal temperature recording is not possible.
体温反映了动物的健康状况和/或疾病情况。在临床检查中，体温测量是兽医的基本步骤。传统的方法是直肠测温，对某些动物来说特别有压力，尤其是对猫来说。一种压力较小的替代方法，如红外热成像相机，已在医学的各个领域用于诊断、预后和正确的治疗方法。为了评估红外热成像在评估眼部温度方面的有用性，本研究纳入了 20 只不同品种（欧洲、暹罗和波斯，4-6 岁，平均体重 4.3 ± 0.30 公斤）的猫。为了评估通过热成像评估眼部温度作为测量动物体温的工具的适用性，将获得的值与通过数字热像仪在每只猫中记录的直肠温度值进行比较。左眼和右眼之间没有差异；眼部温度和直肠温度值之间记录到约 1.19°C 的差异（p < 0.0001）。直肠温度和眼部温度呈正相关（p < 0.0001；r = 0.93）。总之，我们表明，眼部温度是一种替代的体温测量方法，可用于猫的临床评估，特别是在无法记录直肠温度的情况下。
