Background:
Thyroid eye disease (TED; also known as thyroid - associated orbitopathy, Graves ophthalmopathy) is an autoimmune inflammatory disease which presents in typical signs and symptoms such as deep orbital pain, chemosis with or without caruncular edema, unilateral or bilateral proptosis, eyelid retraction, eyelid edema or erythema, restrictive strabismus and compressive optic neuropathy.
Objective:
The aim of this study was to investigate the role of thermal camera in the assessment of thyroid eye disease (TED) activity compared to the Clinical Activity Score (CAS) scale, exophthalmometry values, and thyroid hormone and antibody levels.
Methods:
A total of 50 patients participated in this cross-sectional study of whom 29 were in the active phase of TED according to the sum on CAS scale and 21 patients in the inactive phase. The Flir E8® thermal camera was used to measure the temperature of the orbital area and the values were compared with the CAS scale, exophthalmometry values and thyroid hormone and antibody levels.
Results:
Higher values of temperature (p>0.0001), CAS score (p>0.0001), exophthalmometry (p=0.022), FT4 (p=0.0176) and TRAb (p=0.0091) were found in patients in the active phase of TED. Temperature of orbital area showed statistically significant positive correlation with CAS scale (p=0.0001), exophthalmometry values (p=0.0022) and anti-TPO levels (p=0.019).
Conclusion:
Thermal camera showed higher values of the temperature of the orbital area in patients in the active phase of the disease and positively correlated with the CAS scale, exophthalmometry findings and anti-TPO levels.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
