| Cranial nerve palsies of the third, fourth and sixth cranial nerves may occur, affecting extraocular motility. |
|
| The size of the motor unit in this muscle approximates the size of that in the extraocular muscles, less than about ten muscle fibers. |
|
| Infiltration of extraocular muscles may lead to moderate to severe restriction of movement. |
|
| It may be absent on one side, in which case the extraocular muscle usually innervated by the abducens is supplied by the oculomotor nerve. |
|
| Background: Porous orbital implants allow fibrovascular ingrowth and integration with the extraocular muscles. |
|
| The nervous connections of this muscle are closely related to those of the extraocular muscle required to elevate the eye, so that when the eye looks upward the upper eyelid tends to move up in unison. |
|
| The treatment for intermittent exotropia is surgical, consisting of weakening and strengthening the appropriate extraocular muscles to realign the eyes. |
|
| Common signs and symptoms include diplopia, enophthalmos, infraortbital hypoesthesia, and decreased extraocular movements. |
|
| In fact, the extraocular muscles do contain two types of muscle fibre with characteristically different nerve supplies, and some recent studies tend to support this view of a dual mechanism. |
|
| The levator is innervated by the third cranial nerve the oculomotor nerve that also innervates some of the extraocular muscles concerned with rotation of the eyeball, including the superior rectus. |
|
| Rotation of the head in any direction is detected by the semicircular canals, and a velocity signal is then passed via the vestibular nuclei to the somatic and extraocular muscles. |
|
| The status of cranial nerves III, IV, and VI was assessed by using extraocular muscles and cover test. |
|
| Her pupils were equally round and reactive to light, and the extraocular muscles were intact. |
|
| His extraocular muscles were intact, and his pupils were equal, round, and reactive. |
|
| This integration partly occurs in the vestibular nuclei, the source of secondary neurons destined for the extraocular muscle nuclei of both sides. |
|
| Patient with purely extraocular manifestations from a pit viper snakebite. |
|
| Symptoms of intracranial mass effect, including visual field loss, obstructive hydrocephalus, and extraocular palsy of the cranial nerves, may occur. |
|
| Extraocular movements and the visual fields with direct confrontation were normal. |
