FERREIRA, Yeiley et al. Clinical and sonographic relationship associated with thyroid orbitopathy. Salus [online]. 2016, vol.20, n.1, pp.34-42. ISSN 1316-7138.

This paper seeks to qualify and quantify non detectable clinical changes in the initial stages of thyroid disease, through orbit ultrasound and Doppler color duplex ultrasonography; as well as to measure the hemodynamic values of the ophthalmic artery and vein for early detection of observable changes in the optic nerve. Descriptive, cross-sectional and correlational field study of 80 patients, 40 patients diagnosed with thyroid disease and 40 control group patients, who underwent orbital color Doppler ultrasound from July 2006 to December 2007. From the thyroid disease group, 90% were female and 10% male; 75% were between 25-59 years, 45% with hyperthyroidism, 35% with hypothyroidism and 10% euthyroid; 35% had positive smoking habits and 47.5% caffeine habits. 87.3% with <23mm of Exophtalmometry. Moderate reflectivity was present in 136 muscles (43%) with predominance in the upper-right lifting complex of the upper eyelid. Pulsatility index, resistance index and systolic peak velocity of the ophthalmic artery were elevated in hyperthyroidism subjects. Indices of the ophthalmic vein as V1 and V2 were elevated in all groups (hyper, hypo and euthyroid). It is concluded that the orbital eco evaluates quantitative and qualitative alterations such as edema and fibrosis, which are significant in the diagnosis and monitoring of these patients. The Doppler echo revealed significant hemodynamic changes in pulsatility index parameters and systolic peak velocity in hyperthyroidism patients.
