Remarkable bilateral proptosis, large prolapsed lacrimal glands, and enlarged extraocular muscles most prominently in the superior, medial, and inferior rectus muscles, with impression on the optic nerves on both sides, especially in the orbital apex.
Thickened mucosa in paranasal sinuses.
Case Discussion
This case illustrates how the enlarged extraocular muscles in the orbital apex can exert pressure on the optic nerves via orbital apex crowding, thus threatening visual acuity. This is in addition to proptosis, caused by proliferation of intraorbital fat.
