Background and Purpose: To add to the literature a case of isolated third nerve paresis involving the nerve fascicles subserving the superior rectus and the levator palpebrae muscles from brain stem infarction and presenting the characteristics of central disruption of binocular vision fusional amplitudes. Case Report: One patient with an old intracranial aneurysm and with old and recent brain stem infarcts and no other neurological manifestations, demonstrating findings characteristic of isolated paresis of the superior rectus and levator palpebrae muscles is reported. Conclusion: This dual involvement of the superior rectus and levator palpebrae muscles supports the anatomical arrangement of the ocular motor nucleus fascicles in the midbrain, clarified by experimental studies on animals and clinical data in humans and emphasizes the juxtaposition of the superior rectus and levator palpebrae fascicles and placing the levator palpebrae muscle fascicle lateral to the medial rectus fascicle in the ...

PURPOSE. To examine the distribution of myosin-binding protein C (MyBP-C) in human extraocular muscles (EOMs) and to correlate the myosin heavy chain (MyHC) and the MyBP-C composition of the fibers.. METHODS. Samples from 17 EOMs, 3 levator palpebrae ( LP), and 6 limb muscles were analyzed with SDS-PAGE and immunoblot or processed for immunocytochemistry with monoclonal antibodies (mAbs) against MyBP-C-fast, MyBP-C-slow, MyHCIIa, MyHCI, MyHCsto, MyHC alpha-cardiac, and MyHCemb.. RESULTS. In the limb muscle samples, fast fibers were labeled with anti-MyBP-C-fast and anti-MyBP-C-slow, whereas the slow fibers were immunostained with anti-MyBP-C-slow only, in accordance with previous studies. In 11 EOM samples MyBPC-fast was not detected, and weak staining with anti-MyBP-Cfast was seen only in a few fibers in the proximal part of 2 muscles. The mAb against MyBP-C-slow labeled all fibers, but fibers containing MyHCI were generally more strongly stained. In the levator palpebrae, immunostaining with ...

Background: There are many surgical approaches to treat sixth nerve palsy depend on residual lateral rectus function, which the vertical rectus muscle transpositions (VRT) procedure is the surgical of choice in complete sixth palsy. VRT procedures, including full-tendon and partial tendon transpositions, often are combined with medial rectus muscle weakening. Partial tendon VRT procedure aimed to create success rate similar to full-tendon transposition with reduced risk of anterior segment ischemia when combined with simultaneous ipsilateral medial rectus muscle recession. ...

The supraorbital artery is an artery of the head. It springs from the ophthalmic artery as that vessel is crossing over to the medial side of the optic nerve. It passes upward on the medial borders of the superior rectus muscle and levator palpebrae superioris, meeting the supraorbital nerve accompanies it between the roof of the orbit and levator palpebrae superioris to the supraorbital notch. When passing through the supraorbital notch it divides into a superficial and a deep branch. Its terminal branches anastomose with branches of the supratrochlear artery and the superficial temporal arteries. This artery supplies the levator palpebrae superioris, the diploë of the frontal bone, the frontal sinus, the upper eyelid, and the skin of the forehead and the scalp. This artery may be absent in 10% to 20% of individuals. The arteries of the face and scalp. Bloodvessels of the eyelids, front view. supraorbital artery This article incorporates text in the public domain from the 20th edition of ...
For patients with no apparent overaction of the oblique muscles or a pattern inconsistent with oblique dysfunction, vertical transposition of the horizontal muscles is performed. The muscles are transposed from one-half to a full tendon width. The medial rectus muscles are always moved toward the apex of the pattern (ie, upward in A patterns and downward in V patterns). The lateral rectus muscles are moved toward the open end (ie, upward in V patterns and downward in A patterns). A useful mnemonic is MALE: medial rectus muscle to the apex, lateral rectus muscle to the empty space. These rules apply whether the horizontal rectus muscles are weakened or tightened (Fig 10-4).. If transposition of horizontal rectus muscles is used to treat pattern strabismus when there is associated ocular torsion, it will exacerbate the torsion (extorsion with V pattern and intorsion with A pattern), which itself can contribute to the pattern. Conversely, when rectus muscle transposition is used to treat torsion, ...
The extraocular muscles are one of few skeletal muscles that are structurally and functionally intact in Duchenne muscular dystrophy. Little is known about the mechanisms responsible for differential sparing or targeting of muscle groups in neuromuscular disease. One hypothesis is that constitutive or adaptive properties of the unique extraocular muscle phenotype may underlie their protection in dystrophinopathy. We assessed the status of extraocular muscles in the mdx mouse model of muscular dystrophy. Mice showed mild pathology in accessory extraocular muscles, but no signs of pathology were evident in the principal extraocular muscles at any age. By immunoblotting, the extraocular muscles of mdx mice exhibited increased levels of a dystrophin analog, dystrophin-related protein or utrophin. These data suggest, but do not provide mechanistic evidence, that utrophin mediates eye muscle protection. To examine a potential causal relationship, knockout mouse models were used to determine whether eye muscle
DR MARMOR: This patient is a 6-year-old who has a right superior oblique paresis. And he has a large vertical deviation in primary position of about 25 prism diopters. And so were going to do some investigation first on whether the superior oblique in the right eye has a normal tone or whether it may be lax. So he has inferior oblique overaction, and well be recessing the inferior oblique, but for the amount of deviation in primary position, that wouldnt be enough to take care of the vertical deviation. So we would need to add a second muscle. The second muscle would be a tuck of the superior oblique, if its in fact lax, or it could be recession of the inferior rectus on the other side. So were gonna determine that with forced duction testing.. ,, And can you just again summarize - I know youve been talking about it all week. Tell us why you do forced ductions, and how you do them. Very slowly just tell us: What are the purpose of forced ductions, and what are you testing?. DR MARMOR: In ...
Next, we compared the predicted impact of extorsion of the rectus muscle pulleys on binocular eye alignment with the clinical measurement in three patients. The location of each rectus muscle pulley was shifted both vertically and horizontally in the ocular simulator software (Eidactics) by an amount quantified by analysis of the corresponding CT images. Eye alignment for patients with 0 to 2°, 20°, and 32° of extorsion of the rectus muscle pulleys are shown as Hess-Lancaster-type plots in Figure 4. Eye position predicted by the ocular simulator software (Eidactics) in central gaze and at eccentricities of 30° upgaze, downgaze, right gaze, and left gaze in 2.5 mm intervals is indicated by the circles. Eye position determined from clinical examination in central gaze and at eccentricities of 30° downgaze and 30° upgaze is represented by the pluses (+). Figure 4A shows the horizontal and vertical eye position in a patient without extorsion of the pulleys. The model predicted normal eye ...
Introduction: The extraocular muscles (EOMs) are considered a separate class of skeletal muscle, allotype. Myosin is the major contractile protein in muscle. The myosin heavy chain (MyHC) isoforms are the best molecular markers of functional heterogeneity of muscle fibers. The relaxation rate, reflects the rate at which Ca2+ is transported back into the sarcoplasmic reticulum (SR) mostly by SR Ca2+ATPase (SERCA). Myosin binding protein C (MyBP-C), plays a physiological role in regulating contraction. The laminins (Ln) are the major non-collagenous components of the basement membrane (BM) surrounding muscle fibers and are important for muscle fiber integrity.. Methods: Adult human EOMs were studied with SDS-PAGE, immunoblots and immunocytochemistry, the latter with antibodies against six MyHC, 2 SERCA, 2 MyBP-C and 8 laminin chain isoforms. The capillary density was also determined.. Results: Most fibers contained a mixture of MyHC isoforms. Three major groups of fibers could be distinguished. ...
Planned strabismus repair targeted the recovery and advancement of the apparently slipped medial rectus muscle, recession of the lateral rectus muscle and excision of the mass in toto, if possible. Intraoperative unroofing of a superficial layer of conjunctiva over the mass revealed a chocolate-colored cyst filled with sero-sanguninous fluid, with strands of flaccid extraocular muscle or pseudo-tendon straddling its surface (Figure 3). The color of the fluid was attributed to prior hemorrhage. Although excision in one piece proved technically challenging, an excisional biopsy of one large section of the mass included up to 10 mm of the flaccid medial rectus fibers. A gentle hand-over-hand technique was required to reach the posterior extension of the cyst, enabling recovery of the medial rectus muscle, well posterior to the equator and still attached to the posterior surface of the remaining wall of the cyst via a thin thread of muscle fiber. The body of the medial rectus muscle was recovered, ...
A 16-year-old girl presented with a 2-month history of recurrent (three episodes) right upper eyelid drooping and oedema (figure 1A). Examination showed fullness in the right upper eyelid along with elevation deficit. Visual acuity was 20/20 in each eye, and anterior and posterior segments were essentially within normal limits in both the eyes. To explain the cause, ultrasonography of the orbit for extraocular muscles revealed a large cyst in the superior rectus muscle along with a central hyperechoic spot corresponding to the scolex (figure 1B). Non-contrast CT of the orbit and brain revealed inflammatory thickening of the superior rectus muscle with the central cystic area harbouring the scolex without any intracranial foci (figure 1C). Based on the history and imaging findings a diagnosis of myocysticercosis was confirmed and … ...

TY - JOUR. T1 - Ipsilateral hypertropia after cataract surgery. AU - Capo, H.. AU - Guyton, D. L.. PY - 1996/1/1. Y1 - 1996/1/1. N2 - Background: Reports of acquired strabismus caused by injection of local anesthetics during cataract surgery have increased recently. The authors proposed a mechanism to explain the occurrence of strabismus with apparent overactive muscles after cataract surgery. Methods: The authors studied 19 patients in whom strabismus developed after cataract surgery. Prism and cover test in the diagnostic positions of gaze and forced-duction testing were used to identify the affected muscles. Results: The deviation was greater in the field of action of the presumed tight muscle in 16 of 19 patients. An ipsilateral hypertropia with superior rectus muscle overaction subsequently developed in two patients with an initial hypotropia. An overaction of the ipsilateral lateral rectus muscle causing an exotropia developed in one patient with initially limited abduction. Conclusions: ...

The oculomotor nerve pierces the dura mater on the lateral side of the posterior clinoid process (see Fig 3-24), initially traversing the roof of the cavernous sinus (see Fig 3-25). It runs along the lateral wall of the cavernous sinus and above CN IV and enters the orbit through the superior orbital fissure (see Fig 3-1).. CN III usually separates into superior and inferior divisions after passing through the annulus of Zinn in the orbit (Fig 3-17). Alternatively, it may divide within the anterior cavernous sinus. The nerve maintains a topographic organization even in the midbrain, so lesions almost anywhere along its course may cause a divisional nerve palsy.. The superior division of CN III innervates the superior rectus and levator palpebrae superioris muscles. The larger inferior division splits into 3 branches to supply the medial rectus, inferior rectus, and inferior oblique muscles.. The parasympathetic fibers wind around the periphery of the nerve, enter the inferior division, and ...

Congenital fibrosis of the extraocular muscles, or CFEOM, is a class of rare genetic disorders affecting one or more of the muscles that move the eyeballs. Individuals with CFEOM have varying degrees of ophthalmoplegia (an inability to move the eyes in one or more directions) and ptosis. The condition is present from birth and non-progressive, runs in families, and usually affects both eyes similarly. In the most common form, the superior recti are dysfunctional and the inferior recti, lacking proper opposition, pull the eyes down, forcing the head to be tilted upward in order to see straight ahead.[citation needed] There are three types of CFEOM, numbered 1-3. CFEOM1, the most common type, is now known to be caused by one of several mutations in the KIF21A gene, while CFEOM2 is caused by mutations in the PHOX2A gene. CFEOM3 is caused by mutations in the TUBB3 gene. CFEOM was first named in 1956, although papers describing conditions now known or assumed to be CFEOM appear in the medical ...

There are more than 1 million cesarean deliveries performed annually in the United States, at a rate of 30.2% of all deliveries. Data are limited regarding optimal surgical closure techniques to minimize adhesions at cesarean. Adhesions are implicated in pelvic pain, infertility, difficult repeat surgery, and bowel obstruction. Practice techniques regarding rectus muscle reapproximation vary widely, and there are no data regarding the impact of this step on pain, and some data suggesting a reduction in significant adhesions. Given the frequency of cesarean deliveries, small changes in surgical technique may yield significant benefits.. We hope to learn 1) whether suture reapproximation of the rectus muscles increases pain, and 2) the degree to which suture reapproximation of the rectus muscles alters adhesions when studied in a prospective, randomized trial.. All patients undergoing primary cesarean delivery at Lucile Packard Childrens Hospital (LPCH) will be offered the study. Once consented, ...

Abstract: : Purpose: Temporal expression profiling of developing extraocular muscle (EOM) by high-density DNA arrays and electron microscopy. Methods: Affymetrix U34A arrays and routine EM were used to study EOM gene expression/morphogenic patterns at P0 to P45, 3 replicates/age. A self-organizing map cluster analysis identified patterned trends in gene expression. Results: Of 8,800 genes on arrays, 3,385 were expressed in EOM with ≷ 2x changes during the age range. Of these, genes meeting additional significance criteria were grouped into 12 clusters comprising 4 major trends. Type I cluster genes (411) were highly expressed at birth and downregulated by P14; group included cell cycle, transduction and growth regulation factors. Type II cluster genes (104) were absent/low expressers at P0, some upregulated by P7, but most progressively increased starting by P14; group included muscle differentiation genes. Expression of genes in the type III cluster (62) was high at P0, progressively dropped ...

Infantile esotropia is defined as the onset of constant esodeviation in children less than 6 months of age.There are several other clinical findings that often accompany infantile esotropia including: large amplitude of the angle (greater than 30 prism diopters), dissociated vertical deviation, dissociated horizontal deviation, inferior oblique overaction, latent nystagmus, cross fixation with pseudo abduction deficit, low degree of hyperopia (less than 3 diopters), and amblyopia. The incidence of infantile esotropia is approximately 1%,making this an important issue for pediatric ophthalmologist.. There are multiple surgical techniques used to treat infantile esotropia with the main goal being to align the eyes so that binocular vision may develop.The most common initial treatment is either bilateral medial rectus muscle recessions or unilateral medial rectus muscle recession and lateral rectus muscle resection. For infants with very large angles of esotropia (,60 prism diopters [PD]), surgery ...

Paralysis of the third cranial nerve affects the medial, superior, and inferior recti, and inferior oblique muscles.. The eye is incapable of movement upwards, downwards or inwards, and at rest the eye looks laterally and downwards owing to the overriding influence of the lateral rectus and superior oblique muscles respectively. The reduced response of levator palpebrae superioris results in ptosis - a drooping of the upper eyelid.. A third nerve palsy with pupillary sparing is often termed a medical third palsy and often has an ischaemic or diabetic aetiology.. Full assessment of oculomotor nerve function involves testing of movement, reaction to light, and accommodation. If all of these are normal, PERLA may be written in the notes - pupils equal, reactive to light and normal accommodation. ...
1) I is the olfactory nerve. The olfactory nerve is a characteristic sensory nerve which serves as a smell transmitter to the brain for interpretation.. 2) II is the optic nerve. The optic nerve is purely sensory in nature and is responsible for vision whereby it transits all visual signals emanating from the eyes retina to the brain for interpretation.. 3) III is the oculomotor nerve. The oculomotor nerve is a type of a motor nerve which has the function of coordinating the eyeball and eyelid movements in that it innervates the inferior oblique, inferior rectus, medial rectus, superior rectus, and the levator palpebrae superioris which jointly perform most the movements of the eye.. 4) IV is the trochlear nerve. The trochlear nerve is a motor nerve which innervates the muscle called superior oblique and this helps in turning the eye laterally and downwards.. 5) V is the trigeminal nerve. The trigeminal nerve is both a motor and sensory nerve which obtains sensation directly from the face and ...
The Parks-Bielschowsky three-step test , also known as Park's three-step test or Bielschowsky head tilt test , is a method used to isolate the paretic extraocular muscle , particularly superior oblique muscle and trochlear nerve (IVth cranial nerve), in acquired vertical double vision . It was originally described by Marshall M. Parks . Bielschowsky's head tilt test Step 1: Determine which eye is hypertropic in primary position. If there is right hypertropia in primary position, then the depressors of the R eye (IR/SO) or the elevators of the L eye are weak (SR/IO). Step 2: Determine whether the hypertropia increases on right or left gaze. The vertical rectus muscles have their greatest vertical action when the eye is abducted. The oblique muscles have their greatest vertical action when the eye is adducted. Step 3: Determine whether the hypertropia increases on right or left head tilt. During right head tilt, the right eye intorts (SO/SR) and the left eye extorts (IO/IR). When a healthy
Dissociated horizontal deviation after traumatic brain injury.. Korean J Ophthalmol. 2010 Dec;24(6):377-9. Authors: Lee TE, Cha DS, Koh SB, Kim SH. A 4-year-old boy visited the hospital with exotropia after brain hemorrhage caused by trauma. He had undergone decompressive craniectomy and cranioplasty 18 months prior to presentation at our hospital. An alternate prism cover test showed more than 50 prism diopters (PD) of left exotropia when he was fixing with the right eye and 30 PD of right exotropia when he was fixing with the left eye at near and far distance. On the Hirschberg test, 60 PD of left exotropia was noted in the primary position. Brain computerized tomography imaging performed 18 months prior showed hypodense changes in the right middle cerebral artery and anterior cerebral artery territories. Subfalcian herniation was also noted secondary to swelling of the right hemisphere. The patient underwent a left lateral rectus muscle recession of 7.0 mm and a left medial rectus muscle ...

The sclera is the opaque (usually white), fibrous, protective layer of the eye containing collagen and elastic fibers.[1] In children, it is thinner and shows some of the underlying pigment, appearing slightly blue. In the old, however, fatty deposits on the sclera can make it appear slightly yellow. The sclera forms the posterior five sixths of the connective tissue coat of the globe. The sclera maintains the shape of the globe, offering resistance to internal and external forces, and provides an attachment for the extraocular muscle insertions. The thickness of the sclera varies from 1mm at the posterior pole to 0.3 mm just behind the rectus muscle insertions. ...

All of the patients were injected in the inferior obliques, and two cases were also injected in the inferior rectus. The number of injections ranged between four ...
The extra-ocular, or extrinsic eye, muscles are a series of small muscles that arise from the pre-otic somites in the developing head. Associated with these somites are the three ventral motor cranial nerves (III or the oculomotor, IV or the trochlear, and VI or the abducens) rostral to the developing ear. The seven extra-ocular muscles encircle the eye within the orbit. Six of the seven muscles attach to the sclera of the eye and produce the complete range of eye movements. The seventh muscle moves the upper eyelid out of the visual pathway. The six muscles of the eyeball are an incredibly stable muscle group over the long history of vertebrate evolution. Across the entire range of vertebrate animals, from fish to mammals, the six extra-ocular muscles show little variation. These intricately controlled muscles have some of the highest neuron to muscle fiber ratios in the body, with motor units consisting of approximately ten muscle fibers. The levator palpebrae superioris, the only member of ...
In 2007, I published in the British Journal of Ophthalmology a new, minimally invasive access technique for primary horizontal rectus muscle recession and plication and its results.1 I suggested performing these types of surgeries using only two, small parainsertional openings. The term minimally invasive surgery (MISS) was proposed for all types of strabismus surgeries (1) minimizing the … ...

The present invention is directed to a drug delivery device for a human eye. The human eye has a sclera, an inferior oblique muscle, and a macula. The device of the present invention includes a pharmaceutically active agent, and a geometry that facilitates the implantation of the device on an outer surface of the sclera, beneath the inferior oblique muscle, and with the pharmaceutically active agent disposed above the macula. Methods of delivery a pharmaceutically active agent to the posterior segment of the human eye are also disclosed.
Obliques that form the side of the body, often loses necessary for the development of load. The lag in the development of these muscle groups due to the fact that most of the people for strengthening the abdominal muscles do the twist and other variations of this exercise, in which the oblique muscles are not as active as direct muscle. Therefore, in order to develop the muscles laterally and to give it relief, the need to separately work out the oblique muscles of the press. Also, be sure to adhere to a special diet, thanks to which decreases the amount of abdominal fat, and relief of the abdominal muscles begins to be clearly seen. The complex of exercises for the oblique muscles of the press ...
In Part 1 we reviewed evidence for the importance of proprioception in eye muscle function. The graphic above is from a paper on sensory control of extraocular muscles, postulating proprioceptive pathways based on known connections. if proprioceptive signals are generated in the palisade endings on multiply innervated extraocular muscle fibers (MIFs), the information may first…

Strabismus surgery should NOT be considered as just a cosmetic procedure. Misaligned eyes are not a normal state. Misaligned eyes affect ones ability to see, communicate, gain social acceptance, find a job, make friends, seek a life partner and avert depression. Therefore strabismus surgery is more proprely referred to as a RECONSTRUCTIVE rather than just cosmetic. ...
If I do use the restasis he said I am on this for at least 3 months to see if it helps. Ugh, I dont know if I should use it or not. It has been about 14 weeks since my lasik surgery. Well, then he put me behind the equipment (dont know what it is called) to check my vision and it was blurry but as soon as he overcorrected me I could see perfectly. I was so happy. He said he corrected me for my perscription but that I was overcorrected in my glasses and contacts before the surgery. He said if he overcorrected me then I would need reading glasses much sooner. But my answer is I would rather see like I did and need reading glasses sooner than see fuzzy as I am now ...

Tetanus neurotoxin (TeNT) cleaves synaptobrevin, a protein involved in synaptic vesicle docking and fusion, thereby preventing neurotransmitter release and causing a functional deafferentation. We injected TeNT into the lateral rectus muscle of adult cats at 0.5 or 5 ng/kg (low and high dose, respectively). In the periphery, TeNT slightly slowed motor axon conduction velocity, and at high doses, partially blocked neuromuscular transmission. TeNT peripheral actions displayed time courses different to the more profound and longer-lasting central actions. Central effects were first observed 2 days postinjection and reversed after 1 mo. The low dose induce depression of inhibitory inputs, whereas the high dose produce depression of both inhibitory and excitatory inputs. Simultaneous recordings of eye movement and neuronal firing revealed that low-dose injections specifically reduced inhibition of firing during off-directed saccadic movements, while high-dose injections of TeNT affected both inhibitory and
The Sherringtons law of reciprocal innervation, also called Sherringtons law II explains how a muscle will relax when its opposite muscle is activated. in other words, when a muscle contracts, its direct antagonist relaxes to an equal extent allowing smooth movement..for example, when the muscle of lateral rectus in the right eye is contract, it will relax the reciprocal muscle (medial rectus)of the same eye...and the same time it will also contract the medial rectus of the other eye ...

Look, there they are, Technicolored for your convenience (actually they are all different colors, really, thats why Colorado is really pink because its pink on the map. Anyway, I didnt draw many deep layer muscles because, well, they are deep layered muscles and not really vital to understanding facial expression as they act to assist the upper layer muscles. The buccinator (sounds like buck-sin-a-tor not like buccaneer) is about as deep layer as I got here. The levator palpebrae is under the orbicularis oculi and opens the eye, its a deep layer muscle too. Youll notice that I included origin and insertion of these muscles (labeled as O and I) because its very important to know how the muscle works and therefore changes to the face so it can express. Origination of a muscle means where the muscle pulls to. Think of origination as the place where you dig in your heels at the start of a tug-o-war. Insertion means the part that is being pulled. If you were in a tug-o-war against a ...
