• The abducens nerve or abducent nerve, also known as the sixth cranial nerve, cranial nerve VI, or simply CN VI, is a cranial nerve in humans and various other animals that controls the movement of the lateral rectus muscle, one of the extraocular muscles responsible for outward gaze.
• Intraocular malignancies are relatively more frequently treated than extraocular malignancies, likely due to a relatively earlier detection and subsequent treatment.
• An evisceration is the removal of the eye's contents, leaving the scleral shell and extraocular muscles intact.
• The orbital contents comprise the eye, the orbital and retrobulbar fascia, extraocular muscles, cranial nerves II, III, IV, V, and VI, blood vessels, fat, the lacrimal gland with its sac and duct, the eyelids, medial and lateral palpebral ligaments, cheek ligaments, the suspensory ligament, septum, ciliary ganglion and short ciliary nerves.
• The method was based in his theory that the eye does not focus by changing the power of the lens, but rather by elongating the eyeball through use of the extraocular oblique muscles; this model contradicted mainstream ophthalmology and optometry then and now.
• The inflammation of the Tenon capsule resulting from heightened blood flow may also affect the lacrimal gland and the extraocular muscles.
• A full eye examination consists of an external examination, followed by specific tests for visual acuity, pupil function, extraocular muscle motility, visual fields, intraocular pressure and ophthalmoscopy through a dilated pupil.
• Cavernous sinus thrombosis, associated with infection of the paranasal sinuses, proptosis, periorbital oedema, retinal haemorrhages, papilledema, extraocular movement abnormalities, and trigeminal nerve sensory loss.
• The concept of reciprocal innervation as applicable to the eye is also known as Sherrington's law (after Charles Scott Sherrington), wherein increased innervation to an extraocular muscle is accompanied by a simultaneous decrease in innervation to its specific antagonist, such as the medial rectus and the lateral rectus in the case of an eye looking to one side of the midline.
• In ophthalmology, tonus may be a central consideration in eye surgery, as in the manipulation of extraocular muscles to repair strabismus.
• Unlike the other extraocular muscles (recti and superior oblique), the inferior oblique muscle does not originate from the common tendinous ring (annulus of Zinn).
• Evisceration – removal of the iris, lens, and internal eye contents, but with the sclera and attached extraocular muscles left behind.
• Aside from asymmetric ptosis (which becomes worse with fatigue, sustained upgaze, and at the end of the day) and variable limitation of extraocular muscles/diplopia, other clinical signs of ocular MG include gaze-evoked nystagmus (rapid, involuntary, oscillatory motion of the eyeball) and Cogan’s lid twitch (upper lid twitch present when patient looks straight ahead after looking down for 10–15 seconds).
• Notably, there is no restriction of extraocular movements, no diplopia, and often no apparent ocular signs such as proptosis.
• An extraocular implant (also known as eyeball jewelry) is a cosmetic implant involving a tiny piece of decorative jewelry which is implanted within the superficial, interpalpebral conjunctiva or sclera of the human eye.
• Other than childbirth, possible applications of levobupivacaine include upper and lower limb surgery, as well as eye surgery, where it blocks the extraocular muscle, highly efficient and convenient for patients undergoing vitreoretinal anterior segment or cataract surgery.
• The idea of treating strabismus by cutting some of the extraocular muscle fibers was published in American newspapers by New York oculist John Scudder in 1837.
• Other ocular abnormalities include ophthalmoplegia (paralysis of one or more of the extraocular muscles) and other types of strabismus, uveitis, and heterochromia of the iris.
• A common misconception about EOG is that the measured potential is the electromyogram of extraocular muscles.
• A peritomy is a procedure carried out during eye surgery, where an incision is made around the limbus, usually to expose the sclera and/or extraocular muscles for a variety of surgical procedures.
