Contrast CT image and schematic drawing of the coronal plane orbit.
(a) Contrast CT image through the mid-left orbit in a patient with mild TED. The superior rectus muscle (SR) can be distinguished from the superior ophthalmic vein and the levator palpebrae. (b) Schematic drawing of the coronal plane orbit. The area of the IR appears significantly larger than the area of the SR.
