Archives: researchers, using sophisticated 3D CT scanning, have demonstrated that eyebrow fat increases in volume in thyroid eye disease, just like the fat and soft tissue in the orbit. They suggest that eyebrow fat be examined more carefully and that standards and normals be established, so that eyebrow fat can be better addressed when surgical correction of thyroid eye disease is considered. Typically it is ignored as surgeons focus on the retrobulbar and orbital tissue that causes disfiguring exophthalmos (bulging out) of the eyeballs.
