Action: Elevates, adducts, androtates medially the eye . Combined with the action of the superior rectus muscle, it directs the eye upward (Fig. The superior oblique is a fusiform (spindle-shaped) muscle belonging to the extraocular group of muscles. To evaluate the outcome of bilateral symmetric and asymmetric superior rectus (SR) recessions in patients with bilateral dissociated vertical deviation (DVD) without oblique dysfunction and determine factors that might influence the surgical outcome. This nerve may be stretched by mobilizing the superior aspect of the eyeball in an essentially caudad direction, during the cranial expansion phase. Patients with a minimum follow-up of 6 months were included. We included 65 unselected consecutive cases of patients with purely tonic esotropias who underwent surgery, Purpose For the LR group, mean preoperative deviation was 35.7Δ ± 3.5Δ at distance and 16.3Δ ± 3.9Δ at near. Action. ipsilateral medial rectus resection (LR+MR group). Description: Origin: Superior part of the common tendinous ring that surrounds the optic canal Insertion: Superior surface of the anterior part of the sclera Actions: Rolls the eye upward Nerve supply: Oculomotor nerve Blood supply: Internal carotid artery. Originates in common with the rectus muscles, courses along the medial wall of the orbit, and then turns and loops through a fibrous sling, called the trochlea, before inserting on the superolateral region of the eyeball. for the actions of superior and inferior recti and superior and inferior obliques. Results: (Raymond Jack). the contractile tissue that effects the movement of and within the body. Each of the eye’s recti muscles originates from the common tendinous ring (sometimes referred to as the annular tendon or annulus of Zinn), This is a fibrous ring of connective tissue that surrounds the optic nerve where it connects to the orbit. These actions are more complicated when the patient is directed to look vertically upward or downward, or horizontally inward ... rectus or left superior oblique muscle palsy. In this workshop, participants discuss the characteristics and most current methods for assessing and quantifying the deviation and explore the potential etiologies, clinical characteristics, and indications for surgical intervention and nonsurgical management of DVD. Extraocular muscle actions. Inferior rectus muscle. The main advantage is improvement in distance alignment while selectively reducing the near angle in patients with different levels of AC/A ratios. A satisfactory result was defined as orthophoria or esotropia <10 prism diopters (Δ) at near and distance with reduction of the near-distance disparity to <10 Δ. orbicularis oculi. The technique was particularly helpful for the inferior rectus muscle (85.8% reduction), followed by the medial rectus (66%), lateral rectus (55%), and superior rectus muscles (55%). The mean medial rectus resection was 5.5 ± 0.6 mm. The superior rectus is an eye muscle, controlling the eye as it moves up. In the primary position (looking straight ahead), the superior rectus muscle's primary No complications or muscle slippage occurred. The vector summation of these actions results in moving the visual gaze up and in. Description: Origin: Superior part of the common tendinous ring that surrounds the optic canal Insertion: Superior surface of the anterior part of the sclera Actions: Rolls the eye upward Nerve supply: Oculomotor nerve Blood supply: Internal carotid artery. Superior rectus muscle - Location. moves the scalp as in a surprised facial expression. This problem has been solved! Results A total of 20 procedures in 20 patients were included. Explanation of superior rectus muscle The median DVD reduced from 9 PD (IQR, 6-14 PD) to 5 PD (IQR, 3-8 PD) in the right eye (P = 0.015) and 9 PD (IQR, 7-12 PD) to 6 PD (IQR, 3-10 PD) in the left eye (P = 0.016) after surgery. Please see each individual article for more detailed description. All patients, regardless of the size of AC/A ratio and the amount of near-distance disparity, had satisfactory alignments at near and distance fixations, with residual near-distance disparity of <10Δ. The most common type of vertical strabismus is a trochlear nerve palsy. Found insideThis important new text reflects the importance of correlating clinical signs of disorders in the oculomotor system with their neuroanatomic and neurophysiologic architecture. To determine the effect of the rectus extraocular muscle pulleys on the fadenoperation, an operation designed to fixate the posterior muscle belly to the underlying retroequatorial sclera. Muscle Nerve. Packed with easily understood, up-to-date and clinically relevant material, this is the only physiology book junior anaesthetists will need. Methods Methods: Conclusion Methods Superior rectus muscle View Related Images. They act to control the movements of the eyeball and the superior eyelid. Function. origin: incisive fossa of the mandible; insertion: skin of the chin innervation: facial nerve; action: raises skin of chin and elevates lower lip Gross anatomy Origin. This is the basis for Bielschowsky's test for a cranial nerve IV palsy. On the synoptophore, there was a superior rectus underaction in both eyes of –0.48 degrees and a median of 0 degrees (IQR = –1 to –1 degrees).

The medical records of adult patients undergoing combined adjustable resection-recession surgery on a single rectus muscle at one institution from 2008 to 2019 were reviewed retrospectively. Methods If the muscle were to contract by itself it would intort the eye and turn it downwards and outwards, but under normal circumstances it does not act in isolation but in combination with other extraocular muscles. The mean near-distance disparity (NDD) was 11.4Δ ± 2.7Δ. The main outcome measure was postoperative angle of DVD at the end of six postoperative months and success was identified as absence of manifest DVD . Access scientific knowledge from anywhere. There was no difference in successful outcome with respect to age, sex, preoperative horizontal deviation, preoperative vertical deviation, postoperative residual horizontal deviation, surgical technique, asymmetry of SR recession, and magnitude of preoperative DVD. To assess the effect of combined resection and recession on the same lateral rectus muscle in patients with true divergence excess sensory exotropia. Purpose: Develops in about 72% of congenital esotropes, 34% of accommodative esotropes, and 32% of intermittent exotropias developed between 1-6 years. origin: incisive fossa of the mandible; insertion: skin of the chin innervation: facial nerve; action: raises skin of chin and elevates lower lip Gross anatomy Origin. The fourth cranial nerve, aka trochlear nerve, innervates the superior muscles. Patients were divided into two groups. Origin. Superior rectus muscle View Related Images. Therefore, it is essential in testing the extraocular muscles to ensure that only one muscle is tested at a time, without influence from another extraocular muscle. The superior rectus muscle is a muscle in the orbit. Bilateral SR recession resulted in a success rate of 63% after single operation for bilateral DVD without oblique dysfunction. In man vertical motion stimulates a response by both the inferior oblique and superior rectus. It extorts the eye and moves it upward and outwards. M15). The tendon is reflected caudally, laterally, and inferiorly beneath the superior rectus to the lateral part of the bulb of the eye, and is inserted onto the scleral surface, behind the equator of the eyeball, the insertion of the muscle lying between the superior rectus and lateral rectus. When the eye is abducted, the rectus muscles are the prime vertical movers. With respect to muscle strength and innervation testing, it is important to consider that multiple muscles can accomplish the same actions about the three principle axes. The technique was particularly helpful for the inferior rectus muscle (85.8% reduction), followed by the medial rectus (66%), lateral rectus (55%), and superior rectus muscles (55%).

Recessions for the maximal deviations were combined with smaller resections using hang-back, nonadjustable sutures. a. Pubic crest and symphysis pubis. The mean maximum eccentric gaze deviation was 21.4(Δ) ± 9.9(Δ) (range,10(Δ)-48(Δ)). Table 8–1 lists the primary and secondary actions of the extraocular muscles. Philadelphia: Lea & Febiger, 1918; Bartleby.com, 2000. www.bartleby.com/107/. In our study combined resection and recession of the same lateral rectus muscle in patients with divergence excess sensory exotropia significantly reduced the NDD, with no adverse outcomes. It is the largest of the extraocular muscles and its only action is adduction of the eyeball. In the primary position (looking straight ahead), the superior rectus muscle's primary function is elevation, although it also contributes to intorsion and adduction. The incisive fossa is a small depression in the body of the mandible lying just below the lateral and central incisor teeth on each side.

To compare outcomes of combined resection and recession on previously unoperated single horizontal or vertical rectus muscles in consecutive adult patients with acquired incomitant deviations minimal in primary gaze and maximal in an eccentric gaze position. To study prospectively the effect of extirpating the proprioceptive impulse at the myotendinous junction combined with recession of the medial rectus muscles in patients with convergence excess esotropia. Conclusions: Check for errors and try again. When the eye is in abduction, the superior oblique muscle pulls the 12 o’clock meridian of the iris toward the nose, rotating the globe around an anteroposterior (Y) axis. Note that the vertically acting muscles also tort the eye, but the torsional forces are balanced when both elevators (superior rectus and inferior oblique) or both depressors (inferior rectus and superior … A satisfactory outcome was defined as orthotropia or esotropia of <10Δat near and distance fixations with available correction and reduction of the distance--near disparity to <10Δ. The superior oblique muscle with its innervation by the trochlear nerve has several unusual features, and it plays a role in neurology disproportionate to its size.

ORIGIN Superior tendinous ring within orbit: INSERTION Superior sclera anterior to equator of eyeball: ACTION Elevates eye. In order to remove this disparity, and resolve that this is a pseudo paresis, we're gonna block this right eye. So the left superior rectus fires to intort the left eye, and that causes the left hypertropia, as the superior rectus fires. Medial rectus muscle. between October 2017 and 2018. Methods: The technique was particularly helpful for the inferior rectus muscle (85.8% reduction), followed by the medial rectus (66%), lateral rectus (55%), and superior rectus muscles (55%). Introduction: Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Mean maximum adduction after medial rectus fadenoperation was 18 degrees (range, 10 to 25 degrees; 13 eyes). The average length of follow-up was 1.7 years (range, 2.4 months to 11.1 years). The medial rectus causes the eyeball to look inwards; the inferior rectus downwards and the superior rectus upwards. Purpose This is retrospective study that evaluates the use of combined recession-resection of the superior rectus muscle in the treatment of dissociated vertical deviation (DVD) DVD is a rare, poorly understood eye motility disorder of unknown etiology. Synonym(s): musculus rectus superior [TA] . Cranial nerve III. The inferior oblique arises from the orbital surface of the maxilla, lateral to the lacrimal groove.

The superior rectus muscle runs from the apex of the orbit anteriorly and temporally and inserts in the eye 8 mm behind the upper limbus (Figure 113.2).When the eye is in primary position, the muscle plane of the superior rectus forms an angle of 23 degrees with the visual axis. Synonym(s): musculus rectus superior [TA] . orbicularis oris. This way these actions are neutralized and the net action is … Inferior rectus muscle - Action. A satisfactory outcome was defined as deviation ⩽10 prism diopters (PD), at near and distance fixation, between 3 and 6 months postoperatively. All patients who underwent bilateral SR recession for bilateral DVD from January 2012 to December 2016 at an eye hospital in New Delhi, India were included. The mean angle of preoperative DVD was 18.09 PD in the right eye and 16.76 PD in the left eye. Conclusion: The fibers then pass anteroinferiorly, deep to the oral mucosa of the vestibule of the mouth, on either side of the midline labial frenulum 1-3,5. Success was defined as absence of manifest DVD in both eyes at the final postoperative visit. Although hyperdeviation of affected eye was reduced in all patients, we didn't eliminate deviation completely. Position caused by unopposed action of: lateral rectus muscle (eye abduction action) innervation = abducens nerve (VI) superior oblique muscle (Adduct and move eye down) innervation = trochlear nerve (IV) Diplopia ("seeing double") - due to a misalignment of the eyes (ptosis may block the vision in one eye, resulting in the absence of diplopia) Selected structure offscreen.

Mean initial deviation was in group I, 19.6 PD and 32.0 PD, in group II, 23.6 PD and 33.5 PD, at distance and near fixation respectively. Aim: Purpose: Forced duction testing was performed prospectively during surgery before and after faden placement. The mean amount of SR recession was 8.9 ±1.4 mm in the right eye and 8.7 ±1.5 in the left eye with symmetrical surgery performed in only 7 patients. Conclusions To assess the effect of combined resection and recession on the same lateral rectus muscle in patients with true divergence excess sensory exotropia. The 4 rectus muscles do not insert at the same distance from the limbus; the medial rectus inserts closest to the limbus, with the inferior rectus, lateral rectus, and superior rectus muscles progressively inserting farther away, resulting in an imaginary spiral termed the spiral of Tillaux. Found insideThe text begins with chapters on performing the general examination of the eye and differential diagnosis. The Theory of Binocular Vision is a book about neurological control theory. In this sense it was far ahead of its time, for the formal development of control theory was many decades in the future when this book appeared in 1868. a. The technique of combined resection–recession is safe, easy and more effective in the treatment of near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results though longer follow-up period is still needed. In our study combined resection and recession of the same lateral rectus muscle in patients with divergence excess sensory exotropia significantly reduced the NDD, with no adverse outcomes. The medical records of 21 patients with bilateral DVD were retrospectively reviewed. Patients and methods Join the community of over 1 million readers. epicranial aponeurosis.
