Anatomical terms of muscle |
The levator palpebrae superioris (Latin for: elevating muscle of upper eyelid) is the muscle in the orbit that elevates the superior (upper) eyelid.

Structure
The levator palpebrae superioris originates on the lesser wing of the sphenoid bone, just above the optic foramen. It broadens and becomes the levator aponeurosis. This portion inserts on the skin of the upper eyelid, as well as the superior tarsal plate. It is a skeletal muscle. The superior tarsal muscle, a smooth muscle, is attached to the levator palpebrae superioris, and inserts on the superior tarsal plate as well.
Innervation
As with most of the muscles of the orbit, it is innervated by the superior division of the oculomotor nerve (Cranial Nerve III). It originates from the Edinger Westphal (E-W) nucleus. This is why, when one turns one's eye upward, the eyelid tends to rise with it.[1] An adjoining smooth muscle, the superior tarsal muscle, is sympathetically innervated and is occasionally considered to be part of the levator palpebrae superioris.
Function
The levator palpebrae superioris muscle elevates and retracts the upper eyelid.
Clinical signifiance
Damage to this muscle, or its innervation, can cause ptosis, the drooping of the eyelid. Ptosis can also be caused by damage to the adjoining superior tarsal muscle, or its sympathetic innervation. Such damage to the sympathetic supply occurs in Horner's syndrome, and presents as a partial ptosis.

- Evidence of ancillary trigeminal innervation of levator palpebrae in the general population.
- Lehman AM, Dong CC, Harries AM, Patel A, Honey CR, Patel MS.Author information Department of Medical Genetics and Child and Family Research Institute, University of British Columbia, C234 4500 Oak Street, Vancouver, BC, Canada V6H 3N1.AbstractThe cranial synkineses are a group of disorders encompassing a variety of involuntary co-contractions of the facial, masticatory, or extraocular muscles that occur during a particular volitional movement. The neuroanatomical pathways for synkineses largely remain undefined. Our studies explored a normal synkinesis long observed in the general population - that of jaw opening during efforts to open the eyelids widely. To document this phenomenon, we observed 186 consecutive participants inserting or removing contact lenses to identify jaw opening. Seeking electrophysiological evidence, in a second study we enrolled individuals undergoing vascular decompression for trigeminal neuralgia or hemifacial spasm, without a history of jaw-winking, ptosis, or strabismus, to record any motor responses in levator palpebrae superioris (LPS) upon stimulation of the trigeminal motor root. Stimulus was applied to the trigeminal motor root while an electrode in levator recorded the response. We found that 37 participants (20%) opened their mouth partially or fully during contact lens manipulation. In the second study, contraction of LPS with trigeminal motor stimulation was documented in two of six patients, both undergoing surgery for trigeminal neuralgia. We speculate these results might provide evidence of an endogenous synkinesis, indicating that trigeminal-derived innervation of levator could exist in a significant minority of the general population. Our observations demonstrate plasticity in the human cranial nerve innervation pattern and may have implications for treating Marcus Gunn jaw-winking.

- Ocular myocysticercosis: an unusual case of ptosis.
- Agrawal S, Ranjan S, Mishra A.AbstractBackground: Cysticercosis is common in endemic countries like India. It can have various clinical manifestations depending on the tissue involved. It refers to a parasitic infestation by Cysticercus cellulosae, the larval form of the pork tapeworm or Taenia solium. Objective: To report an unusual case of ocular cysticercosis involving the levator palpebrae superioris and superior rectus muscle of the right eye. Case description: A young, male adult was diagnosed by Magnetic Resonance Imaging (MRI) scan of the skull and orbit to have right-sided ocular cysticercosis. The patient was treated with oral prednisolone and albendazole, to which he showed a significant improvement. Conclusion: Ocular myocysticercosis can be diagnosed by MRI and be treated medically with steroid and albendazole.
