Oculomotor Muscles
The oculomotor muscles, also known as the extraocular muscles, are a group of six muscles that control the movement and position of the eyeball within the orbit. These muscles include the superior, inferior, medial, and lateral rectus muscles, as well as the inferior oblique and superior oblique muscles. Together, they enable various eye movements such as looking up, down, sideways, and rotating the eyes to follow moving objects or maintain fixation on a single point in space.

Ophthalmologic Surgical Procedures
Ophthalmologic surgical procedures refer to various types of surgeries performed on the eye and its surrounding structures by an ophthalmologist, a medical doctor who specializes in eye care and surgery. These procedures aim to diagnose, treat, or manage a range of eye conditions such as cataracts, glaucoma, retinal disorders, corneal diseases, and eyelid abnormalities. Examples of ophthalmologic surgical procedures include:
Streptococcus constellatus
'Streptococcus constellatus' är en grampositiv bakterie som tillhör streptokocker-gruppen och är en del av den normala munfloran hos många människor. Den kan dock orsaka infektioner i kroppen, särskilt i munsår, struphuvud, lungor, hjärta, blodomlopp och centrala nervsystemet, särskilt vid nedsatt immunförsvar.
Ophthalmoplegia
Ophthalmoplegia är ett medicinskt tillstånd där det uppstår svaghet eller fullständig förlamning (pares eller paralys) i de muskler som kontrollerar ögats rörelser. Detta kan orsaka problem med att fokusera ögat, dubbelseende eller oförmåga att röra ögat överhuvudtaget. Ophthalmoplegia kan vara en permanent eller tillfällig tillstånd och kan drabba ena eller båda ögonen. Det kan orsakas av en rad olika sjukdomar eller skador, inklusive neurologiska sjukdomar som Multipel skleros (MS) och myasthenia gravis, diabetes, trauma till ögat eller ögonhålan, eller som en biverkning av vissa mediciner. I vissa fall kan orsaken aldrig fastställas, vilket kallas idiopatisk ophthalmoplegia.
Oculomotor Nerve Diseases
The oculomotor nerve, also known as the third cranial nerve, controls many of the muscles that move the eye and enable fine-focus adjustments. Oculomotor nerve diseases refer to conditions that affect the function of this nerve, leading to various symptoms such as drooping of the eyelid (ptosis), double vision (diplopia), and difficulty with eye movement. These diseases can be caused by a variety of factors, including nerve damage due to trauma, compression from tumors or aneurysms, inflammation, or degenerative conditions. Treatment for oculomotor nerve diseases varies depending on the underlying cause and may include medication, surgery, or observation.
