Prospective evaluation of infrared thermography of a patient with active Graves’ Ophthalmopathy. Example of thermal images from a male patient, 60-year-old, with GD and active ophthalmopathy, currently using 20 mg of methimazole. At first physical exam: CAS of 7, measure of right eye and left eye was 17 and 15 mm, respectively. TSH and fT4 were, respectively, 0.07 mUI/L and 2.33 m/dL. Thermal evaluation: (a) 38.8°C, right upper eyelid; (b) 39.1°C, right caruncle; (c) 37.8°C, left upper eyelid; (d) 37.8°C, left caruncle. The patient was treated with prednisone 40 mg daily and local care with eyedrops. Methimazole dose was increased and after 6 months orbital decompression surgery was performed in both eyes. At second physical exam: CAS of 2, measure of right eye and left eye was 15 and 12 mm, respectively. TSH and fT4 were, respectively, 1.46 mUI/L and 1.44 m/dL. Thermal evaluation: (e) 35.9°C, right upper eyelid; (f) 35.7°C, right caruncle; (g) 36.1°C, left upper eyelid; (h) 36.3°C, left caruncle.
