The levator palpebrae superioris receives motor innervation from the superior division of the oculomotor nerve. [1] [2] [3] The smooth muscle that originates from its undersurface, called the superior tarsal muscle is innervated by postganglionic sympathetic axons from the superior cervical ganglion.
Tarsorrhaphy is a surgical procedure in which the eyelids are partially sewn together to narrow the eyelid opening. [citation needed] It may be done to protect the cornea in cases of corneal exposure, as a treatment for Graves' ophthalmopathy, Möbius syndrome or after corneal graft surgery. The procedure is performed on the corner of the ...
