Acquired Oculomotor Nerve Palsy - EyeWiki
An acquired oculomotor nerve palsy (OMP) results from damage to the third cranial nerve. It can present in different ways causing somatic extraocular muscle dysfunction (superior, inferior, and medial recti; inferior oblique; and levator palpebrae superioris) and autonomic (pupillary sphincter and ciliary) muscles.
Cranial Nerve III Palsy - StatPearls - NCBI Bookshelf
2023年7月4日 · Third nerve palsy has a variety of etiologies and can be a harbinger of serious pathology. This activity reviews the etiology, presentation, evaluation, and management of CN III palsy and reviews the role of the interprofessional team …
Third cranial nerve (oculomotor nerve) palsy in adults
2024年3月28日 · The third cranial nerve supplies the levator muscle of the eyelid and four extraocular muscles: the medial rectus, superior rectus, inferior rectus, and inferior oblique. These muscles adduct, depress, and elevate the eye. The superior oblique muscle is innervated by cranial nerve IV and the lateral rectus muscle by cranial nerve VI.
Microvascular Non-Arteritic Ocular Motor Nerve Palsies—What …
Patients aged over 50 who present with isolated unilateral pupil-sparing third or isolated fourth or sixth nerve palsies are often labelled as having “microvascular extraocular palsies”. This condition and its management provoke divergent opinions.
Oculomotor nerve palsy - Wikipedia
Oculomotor nerve palsy or oculomotor neuropathy[1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique).
The profiles and clinical significance of extraocular muscle …
2023年12月20日 · Oculomotor nerve palsy (ONP) arises from primary abnormalities in the central neural pathways that control the extraocular muscles (EOMs). Long non-coding RNAs (lncRNAs) have been found to be involved in the pathogenesis of various neuroparalytic diseases.
Diagnosis and surgical management of isolated inferior oblique palsy …
Isolated inferior oblique palsy (IOP) is a rare clinical entity and the least frequent palsy among all those involving the 6 extraocular muscles. The main clinical features of isolated IOP consist of hypotropia and underelevation in adduction of the affected eye, along with absence of restriction on forced duction testing [1] – [2] .
Ophthalmoplegia | Diplopia, Cranial Nerve III & Oculomotor Palsy ...
ophthalmoplegia, paralysis of the extraocular muscles that control the movements of the eye. Ophthalmoplegia usually involves the third (oculomotor), fourth (trochlear), or sixth (abducens) cranial nerves. Double vision is the characteristic symptom in all three cases. In oculomotor paralysis the muscles controlling the eye are affected in such ...
Oculomotor palsy | Causes, symptoms and treatment
There are 7 extraocular muscles: four straight muscles and two oblique muscles, and the upper eyelid levator. They are responsible for moving the eyeballs toward the object of attention in the visual field, and the images perceived by each eye to merge into one in the cerebral visual cortex.
Extraocular Muscle Compartments in Superior Oblique Palsy
To investigate changes in volumes of extraocular muscle (EOM) compartments in unilateral superior oblique (SO) palsy using magnetic resonance imaging (MRI). High-resolution, surface-coil MRI was obtained in 19 patients with unilateral SO palsy and 19 age-matched orthotropic control subjects.
