Thickness of Retro- and Sub-Orbicularis Oculi Fat in Thyroid Eye Disease: Comparison With Controls and Its Influential Factors

Purpose:
To compare the thickness of the retro- and sub-orbicularis oculi fat (ROOF and SOOF) between patients with thyroid eye disease (TED) and controls via MRI and to determine factors influencing fat thickness.
Methods:
This retrospective, comparative, case-control study included 136 patients (272 sides) with TED and 50 control patients (50 sides). The thickness of the ROOF and SOOF was measured on the quasi-sagittal plane through the optic nerve (the central plane) and 6 mm lateral and medial to the central plane at the level through the superior orbital rim and at the level just below the orbital septum in the lower eyelid, respectively.
Results:
The ROOF and SOOF were thickest on the lateral plane (p
