A small portion of this musclecontains a collection of smooth muscle fibres known as the superior tarsal muscle. Damage to the MLF, connecting the abducens nucleus to the opposite oculomotor nucleus, can result in failure of this synchronous gaze. Instead, these muscles allow us to quickly adapt without the necessity of having to engage in significantly effortful, obvious movements. Fig 3 Lateral view of the extraocular muscles. Levator palpebrae superioris is a thin muscle located in the bony orbit above the eyeball. The petrosal obicularis and subcutaneous tissues overly the upper part of the aponeurosis. after they have crossed over from the opposite abducens nucleus). At the time the article was created Frank Gaillard had no recorded disclosures. For example: the right abducens nerve innervates the right lateral rectus muscle. This category only includes cookies that ensures basic functionalities and security features of the website. There are seven extraocular muscles -the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. Trochlear nerve palsy also causes torsional diplopia (as the superior oblique muscle assists with intorsion of the eye when the head tilts). The extraocular muscles (EOM) are responsible for controlling the movements of the eyeball and upper eyelid. 1. Damage to any of the three cranial nerves innervating the extraocular muscles can result in paralysis of the corresponding muscles. Revisions: 43. The following article focuses on these muscles, their functions, and the nerves that innervate them. Early diagnosis and appropriate management of ptosis is essential and critical to avoid the consequences as discussed. This occurs when a lesion affecting the abducens nucleus or PPRF also interrupts MLF fibers en route to the oculomotor nucleus on the same side (i.e. Sound knowledge of its anatomy and adjacent structures is essential for eyelid surgery. Authors Bahram Eshraghi 1 , Hadi Ghadimi 1 , Mojgan Nikdel 1 Affiliation The levator palpebrae superioris is innervated by the oculomotor nerve, a branch of cranial nerve III (CN III). When this occurs, parasympathetic fibers within the oculomotor nerve are typically affected first: as such, an affected person may initially present with pupils that constrict uncharacteristically slowly in response to light. TransconjunctivalLevatorAponeurosis Advancement without Resection of Mllers Muscle in AponeuroticPtosis Repair. Anatomy Lecturer and Anatomy Lead for Geeky Medics. It is often said, the eyes are the windows to the soul. This beautiful literary quote is not exactly a scientifically provable statement but science has shown us over the years that, our eyes are certainly the windows of our body, allowing us to view the world in which we live and everyone and everything contained within it. This connection allows it to play a crucial role in synchronizing horizontal gaze. 2. Isolated nerve palsy presents with horizontal binocular diplopia with ipsilateral impaired abduction and esotropia (inward turning of eye). 2012;85(1012):460-7.

Introduction The extraocular muscles (EOM) are responsible for controlling the movements of the eyeball and upper eyelid. It leaves the sinus and enters the orbit via the superior orbital fissure, along with the oculomotor nerve, the ophthalmic division of the trigeminal nerve, and the abducens nerve. [1] Federal government websites often end in .gov or .mil. 8600 Rockville Pike The oblique muscles are the superior and inferior obliques. This category only includes cookies that ensures basic functionalities and security features of the website. To compensate for this, patients with trochlear nerve palsy tilt their head to the opposite side, in order to fuse the two images. There are seven extraocular muscles the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. CN III palsy with sparing of the pupil is associated with ischemic neuropathy, which typically occurs secondary to microvascular disease. A blepharoplasty may be indicated, however, if there is significant redundancy present and the extra skin will overhang the lashes and obstruct vision after the lid is raised, or it can be done to improve the cosmetic result after ptosis repair [13]. The wide variability of symptoms reflects the potential of the disease at any time to damage any part of the brain or spinal cord. The abducens nerve originates from cells in the abducens nucleus, which is located in the dorsomedial part of the posterior pons, pontine tegmentum, just ventral to the fourth ventricle. There are two oblique muscles the superior and inferior obliques. The superior tarsal muscle attaches along the whole extent of the superior tarsal plate. 2016 Nov/Dec; [PubMed PMID: 27124372], Pan E,Nie YF,Wang ZJ,Peng LX,Wu YH,Li Q, Aponeurosis of the levator palpebrae superioris in Chinese subjects: A live gross anatomy and cadaveric histological study. Mr. Sivesh also had a good result in the visual field rest as the sides of his viewing are not affected by the drooping of this right upper eyelid due to the paralysis of the levator palpabrae superioris muscle (Figure 1, 2). Whitnallssling for poor function ptosis. They all share a common origin, a fibrous ring of connective tissue located posteriorly at the apex of the orbit, called the tendinous ring or the annulus of Zinn. The levator palpebrae superioris muscle origin is the periosteum of the lesser wing of the sphenoid bone, superior to the optic foramen. This complex is located at the level of superior colliculus near the midline. Become a Gold Supporter and see no third-party ads. The levator palpabrae superioris muscle originates from the lesser wing of the sphenoid bone [1]. They attach to the posterior surface of the sclera. Lippincott Williams & Wilkins. Bookshelf Watch this to learn all the essentials of ECG interpretation and how to document the most common ECG findings in cardiology! Original Author(s): Oliver Jones Last updated: December 22, 2022 The nerve fibers travel through the cavernous sinus along with CN III,V1,V2 & VI. The only muscle the trochlear nerve innervates is the superior oblique muscle. If the lesion extends to affect medial lemniscus and trigeminothalamic fibers, an affected individual may also present with a loss or reduction in position, vibration, and fine touch sensation in the contralateral arm and parts of the contralateral face respectively. Necessary cookies are absolutely essential for the website to function properly. It provides motor and parasympathetic innervation to some of the structures within the bony orbit. By visiting this site you agree to the foregoing terms and conditions. Unable to process the form. 2020;99(5):430-5. Rather than affecting the oculomotor nerve and crus cerebri on the same side of the brain, shifting of the midbrain leads to stretching of the ipsilateral oculomotor nerve (i.e. eCollection 2021 Feb. Two fibromuscular transverse ligaments related to the levator palpebrae superioris: Whitnall's ligament and an intermuscular transverse ligament. Levator Aponeurosis can be seen to cause uneven creases in the eyelids and are usually diagnosed by and ophthalmologist through a vision test that uses an eye chart can help determine if eyelid drooping is compromising the vision aspects of the individual such as the distance of sight and the movements of the eyeball. It is in this situation where the physiologic variants mentioned above are helpful to understand.[7]. The levator palpebrae superioris (LPS) muscle is the main retractor of the upper eyelid, responsible for elevating the upper eyelid and maintaining it in an open position. Claude syndrome, otherwise known as a central midbrain lesion, is characterized by damage to the oculomotor nerve, the red nucleus, and cerebellothalamic fibers in the midbrain. The axons of LMNs are considered as part of the cranial nerves themselves, with their axons projecting via the cranial nerves to the muscles of the face, head, and neck. Would you like email updates of new search results? These axons pass through the red nucleus and emerge from the ventral midbrain medial to the crus cerebri. Theaponeurotic approach to congenital ptosis. Kenhub. The superior tarsal muscle has a unique function in that it assists the levator palpebrae superioris by maintaining the elevation of the upper eyelid after the levator palpebrae superioris has raised it. Thus, damage to the MLF between the left abducens nucleus and right oculomotor nucleus will present with loss of adduction in the right eye. For example: when the left abducens nucleus sends signals to the left lateral rectus to abduct, it also sends signals to the right oculomotor nucleus via the MLF. due to neuropathy affecting levator palpebrae superioris +/- enlarged unreactive pupil if present, suggests compression of CN III, because the parasympathetic pupillary fibers are located peripherally in the nerve and are more likely affected by external compression Pathology Etiology "Transcutaneous Blepharoptosis Surgery - Advancement of LevatorAponeurosis." When the PPRF or abducens nucleus is also damaged, this results in loss of lateral deviation of the ipsilateral eye as well as loss of communication with the opposite oculomotor nucleus. on the side of the herniation) and compression of the contralateral crus cerebri against the opposing edge of the tentorium cerebelli, damaging the corticospinal fibers within. Surgery to advance or resect the levator aponeurosis is generally performed through a lid crease incision [11]. The extraocular muscles are located within the orbit, but are extrinsic and separate from the eyeball itself. Weber syndrome, otherwise known as medial midbrain syndrome, presents with a constellation of symptoms referred to as a superior alternating hemiplegia. [. A useful mnemonic for remembering the nerve supply to the extraocular muscles is: The levator palpebrae superioris is a solitary triangular-shaped muscle responsible for elevation of the superior eyelid (striated muscle). Palpebral ptosis: clinical classification, differential diagnosis, and surgical guidelines: an overview. Am J Phys Med Rehabil. The levator palpebrae superioris (LPS) is the only muscle involved in raising the superior eyelid. As such, it is frequently associated with hypertension, diabetes, or hyperlipidemia. All patients should be assessed for tear-film deficiencies prior to the procedure and be warned about the possibility of post-operative irritation if they have a positive Schirmers test [16]. Adapted by Geeky Medics. An important function of the MLF is to connect the abducens nucleus on one side of the brain with the oculomotor nucleus on the opposite side of the brain. Parasympathetic - Supplies the sphincter pupillae and the ciliary muscles of the eye. The four rectus muscles are the medial rectus, lateral rectus, superior rectus, and inferior rectus. As such, an interruption in the MLF between the right abducens nucleus and the left oculomotor nucleus will block signals to the left eye to look right when the right eye looks right: in a patient with this lesion, the right eye will abduct to the right, but the left eye will be stationary, continuing to gaze forward. Isolated Oculomotor Nerve Palsy in Mild Traumatic Brain Injury. giant cell) arteritis, should also be considered as a potential etiology in older adults. Abducens nerve palsy (sixth nerve palsy) results in unopposed adduction of the eye (by the medial rectus muscle), resulting in a convergent squint. Reviewer: Clinically oriented anatomy. J CraniofacSurg17:246-254. Research has determined that the superior tarsal muscle transmits a considerable amount of power to the levator palpebrae superioris when elevating the eyelid. A comprehensive collection of clinical examination OSCE guides that include step-by-step images of key steps, video demonstrations and PDF mark schemes. The oculomotor nerve is the third cranial nerve (CN III). Material and methods: After removing the orbital roof, the LPS' shape and anatomical variations (i.e., the presence of accessory muscular bands or atypical formation of the muscle) were assessed. Work from researchers and anatomists over the years continue to enrich our understanding in the anatomy of the LPS. 3. and transmitted securely. [1][2][3][4] Mr. Ramesh with his resting facial expression. Ettl A, Zonneveld F, Daxer A, Koornneef L. Ophthalmic Res. Case 6: oculomotor nerve palsy due to aneurysm, View Frank Gaillard's current disclosures, see full revision history and disclosures. The post-ganglionic fibres are carried to the eye via the short ciliary nerves. As the tumor grows, it has the potential to occlude the cerebral aqueduct and put pressure on the superior colliculi. It emerges from the anterior aspect of the midbrain, passing inferiorly to the posterior cerebral artery and superiorly to the superior cerebellar artery. A comprehensive collection of medical revision notes that cover a broad range of clinical topics. The name recti is derived from the latin for straight this represents the fact that the recti muscles have a direct path from origin to attachment. Fibers originating from the frontal eye fields project to two regions: the rostral interstitial nucleus of the MLF (riMLF), known as the vertical gaze center; and in the paramedian pontine reticular formation (PPRF), the pontine horizontal gaze center. The oculomotor nerve provides motor and parasympathetic innervation to some of the structures within the bony orbit. There is paralysis of the superior tarsal muscle in this pathology. Fig 1 Attachment of the levator palpebrae superiors to the superior tarsal plate. The levator palpebrae superioris muscle attaches into the tarsal plate and skin of the upper eyelid and is the primary elevator of the eyelid. Eventual impingement of the oculomotor and trochlear nuclei by the tumor can result in a more severe paralysis of eye movement; and if the medial longitudinal fasciculus (MLF) becomes involved, an affected person may also present with nystagmus. These parasympathetic fibers originate from a group of neuron cell bodies in the midbrain called the accessory nucleus of oculomotor nucleus/Edinger-Westphal nucleus. This is in contrast with the oblique eye muscles, which have an angular approach to the eyeball. The nerve courses medially close to the roof of the orbit and reaches the superior oblique muscle to innervate it. Ettl A, Priglinger S, Kramer J, Koornneef L. Br J Ophthalmol. By Waster [CC-BY-2.5] via Wikimedia Commons, [caption id="attachment_8508" align="aligncenter" width="581"], [caption id="attachment_8510" align="aligncenter" width="599"], [caption id="attachment_37471" align="aligncenter" width="477"], [caption id="attachment_10244" align="aligncenter" width="188"]. Other associated signs and symptoms include: These symptomstend to be relapsing and remitting. olfaction, vision, gustation, audition, and balance); CN V (all three branches, the ophthalmic, maxillary, and mandibular) and CN IX play roles in somatic sensory functions; and CN III, CN IV, CN V (the mandibular branch, V3, only), CN VI, CN VII, CN IX, CN X, CN XI, and CN XII are responsible for motor functions. Is Whitnall's ligament responsible for the curved course of the levator palpebrae superioris muscle? If you do not agree to the foregoing terms and conditions, you should not enter this site. Without these muscles and the nerves that innervate them, the process of observation would be completely different: rather than just shifting ones gaze, one would have to turn the whole head to look in any direction. The lateral rectus muscle is an abductor and moves the eye laterally, and side to side along with the medial rectus, which is an . 2016 Aug; [PubMed PMID: 27495084], Esperidio-Antonio V,Conceio-Silva F,De-Ary-Pires B,Pires-Neto MA,de Ary-Pires R, The human superior tarsal muscle (Mller's muscle): a morphological classification with surgical correlations. But opting out of some of these cookies may affect your browsing experience. This situation presents with ipsilateral paralysis of the oculomotor nerve and ipsilateral hemiplegia. The levator palpabrae superioris is a muscle in the orbit that elevates the upper eyelid. The oculomotor nerve innervates the majority of extraocular muscles: the superior rectus and levator palpebrae superioris are innervated by superior division while inferior division innervate , medial, and inferior recti and the inferior oblique. The nerve leaves the cranial cavity via the superior orbital fissure. The abducens nucleus on the right side sends fibers across the midline to the left oculomotor nucleus via the MLF, instructing the left oculomotor nerve to innervate the medial rectus muscle in the left eye, facilitating synchronous movement of these muscles for rightward gaze. Functional anatomy of the levator palpebrae superioris muscle and its connective tissue system. The medial rectus is one of seven extraocular muscles. It creates a pull that acts as a transmitter which functions from inside the orbital cavity to the eyelid [3]. The nerve enters the orbit via the superior orbital fissure along with the oculomotor nerve, the trochlear nerve, and the ophthalmic division of the trigeminal nerve. It runs ventro-laterally in the subarachnoid space of posterior cranial fossa and penetrates the dura lateral to dorsum sellae of sphenoid bone. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. This patient is presenting with a pupil-sparing oculomotor nerve palsy, characterized by the loss of somatic motor function (i.e. J Pak Med Assoc 59:319-321. Innervated by the oculomotor nerve, the levator palpebrae superioris muscle (LPS) origins from the upper part of the annulus of Zinn, also called the common tendinous ring, which is surrounded by the orbital apex muscle, and stretches forward between superior wall of the orbit and superior rectus muscle in the form of the sector [1,2,3]'.The levator palpebrae superioris could be observed . It is important to recognize preoperatively any ptosis that may be obscured by dermatochalasis [22]. 2023 Lo C, Huang C, Hsu C et al. A collection of free medical student quizzes to put your medical and surgical knowledge to the test! The ability to see is accomplished using a combination of both sensory input from the eye (more specifically from the specialized cells of the retina), and motor output from the brain to the muscles around and attached to the eyes. It divides into superficial and deep lamella. This website uses cookies to improve your experience while you navigate through the website. Make the changes yourself here! The trochlear nerve originates from the trochlear nucleus which lies at the level of inferior colliculus in the tegmentum of the midbrain. The superior tarsal muscle has specific physiologic variants when comparing different individuals, and these center around the attachment of the muscle to the superior tarsal plate. They can be divided into two groups; the four recti muscles, and the two oblique muscles. official website and that any information you provide is encrypted Arch Ophthalmol 108:1628-1632. Fibers from these two gaze centers then project to the motor nuclei of the oculomotor, trochlear, and abducens cranial nerves. A 10-year study of this procedure found that, after resecting the superior tarsal muscle, a significant majority of patients with congenital and acquired ptosis were within 1.5 mm of the opposite lid level, and less than 1% required additional surgery. We also use third-party cookies that help us analyze and understand how you use this website. The extrinsic eye muscles right eye lat. Damage to one of the cranial nerves will cause paralysis of its respective muscles.

Occlusion of the cerebral aqueduct can lead to enlargement of the third ventricle and eventually hydrocephalus. Horner's syndrome refers to a triad of symptoms produced by damage to the sympathetic trunk in the neck: Horner's syndrome can represent serious pathology, such as a tumour of the apex of the lung (Pancoast tumour), aortic aneurysm or thryoid carcinoma. Upper eyelid gold weight implantation in the Asian patient with facial paralysis. A collection of surgery revision notes covering key surgical topics. Surgeries which involve repair of ptosis, or upper eyelid correction procedures, will usually encounter Muller's muscle and should be very precise in adjustments when resecting portions of the upper eyelid. Ptosis is a frequently encountered eyelid malposition in patients of all ages [20]. All rights reserved. The technique to treat the muscle depends on the position of the ptosis and the function of the levator palpabrae muscles as well as the age factor plays a role [10]. CN III also provides motor control to several other extraocular muscles of the eye . The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The visual acuity test showed that he had a 20/20 vision on both sides of his eyes and has no signs of long-sightedness or short- sightedness. Licence: [CC BY]. Since the function of the superior tarsal muscle is to maintain the elevation of the eyelid, it is then easy to understand that damage to this muscle will result in ptosis of the affected eye. . Contraction of the medial rectus adducts the eye, both medial recti act together for convergence. The nerve fibers travel forward between the duraand apex of the petrous temporal bone to enter the cavernous sinus. FOIA Damage to oculomotor nerve leads to ipsilateral paralysis of eye movement: this presents with the eye directed in the down and out eye position, with a dilated, fixed pupil and drooping lid. loss of function of the levator palpebrae superioris; medial, superior, and inferior recti; and inferior oblique muscles) with retention of special visceral afferent function of the constrictor pupillae muscle. a lesion above the tentorium cerebelli), medial portion of the temporal lobe especially the uncal portion herniate across the tentorium. Unlike the recti group of muscles, they do not originate from the common tendinous ring. Licence: [CC BY-SA]. Overview. This is a ring of fibrous tissue,which surrounds the optic canal at the back of the orbit. Contraction of the inferior rectus depresses, adducts, and laterally rotates the eye, and as such it is the main muscle responsible for downward gaze. These signals instruct the left oculomotor nucleus to innervate and thus simultaneously contract the left medial rectus muscle, which pulls the left eye medially so that it also points right at the same time the right eye does. If the medial longitudinal fasciculus (MLF) is lesioned between the motor nuclei of the abducens and oculomotor nerves in the midbrain, internuclear ophthalmoplegiathe inability to adduct the medial rectus muscle of one eye when the lateral rectus of the other eye is abducted for lateral gazecan occur. Vasculitis, such as temporal (i.e. Anatomical structure and its clinical significance of Whitnalls ligament in patients with ptosis.

Before Convergence of the eyes is brought about by both medial recti muscles supplied by somatic efferent component of the oculomotor nerve. LR6 (SO4)3 is a simple mnemonic representing the innervation of the extraocular muscles. An affected individual will also present with eyelid ptosis, or drooping of the eyelid. When there is a weakness, thinning, over stretching or natural injuries besides aging as well as complications due to bhelpharoplasty in the levator muscle will cause the upper eyelid of the eye to not open fully when it is weak [4]. As a result, patients typically present with a down and out appearance of the affected eye. Read more. Oculomotor nerve palsies, or third nerve palsies,result in weakness of the muscles supplied by the oculomotor nerve, namely the superior rectus, inferior rectus, medial rectus, inferior oblique, and levator palpebrae superioris muscles. When this muscle contracts, it releases the suspensory ligament of the lens, which allows the lens to relax and increase its degree of curvature. The presence of an aneurysm should be suspected when the patient does not have a history of diabetes, vascular disease, or other associated risk factors. deviation of the eye in the down and out direction. The site is secure.

Manickam et al. These fibres do not combine with the oculomotor nerve they merely travel within its sheath. In addition, after recognizing that the innervation of the muscle is through the sympathetic nervous system, it is then clear to see that damage to the sympathetic nervous system will also cause ptosis. Ophthalmology 102:2016-2019. There are a total of four rectus muscles, two oblique muscles, and the standalone levator palpebrae superioris. [4], The specific muscle subtype of the superior tarsal muscle is different from the other extraocular muscles. The Anatomic Features of Mller's Muscle: A Histology Study in Chinese. Sympathetic - No direct function, but sympathetic fibres run with the oculomotor nerve to innervate the superior tarsal muscle (helps . The levator palpebrae superioris (LPS) muscle is the main retractor of the upper eyelid, responsible for elevating the upper eyelid and maintaining it in an open position. Medicine. Preganglionic visceral motor axons leave the nucleus and course through the midbrain with somatic efferents both of which constitutes CNIII. D.J. The superior tarsal muscle is visible with the naked eye and is about 15 mm wide by 10 mm long. This can result in damage to a number of structures, including: It should be noted that the exact constellation of symptoms observed will depend significantly on whether the lesion occurs in the rostral or caudal regions of the pons. It emerges from the anterior aspect of the midbrain, passing inferiorly to the posterior cerebral artery and superiorly to the superior cerebellar artery. There are six muscles involved in the control of the eyeball itself. All content published on Kenhub is reviewed by medical and anatomy experts. Note the partial ptosis.
