Frequency. ~2% (children) [ 3] Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. [ 2] The eye that is pointed at an object can alternate. [ 3] The condition may be present occasionally or constantly. [ 3] If present during a large part of childhood, it may result in amblyopia, or ...
Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence of poor vision in one eye.
Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve ), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [ 1] The inability of an eye to turn outward, results in a convergent strabismus or esotropia of which the ...
Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [ 1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called ...
The management of strabismus may include the use of drugs or surgery to correct the strabismus. Agents used include paralytic agents such as botox used on extraocular muscles , [1] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.
Chronic progressive external ophthalmoplegia ( CPEO) is a type of eye disorder characterized by slowly progressive inability to move the eyes and eyebrows. [ 1] It is often the only feature of mitochondrial disease, in which case the term CPEO may be given as the diagnosis. In other people suffering from mitochondrial disease, CPEO occurs as ...
Sudden, acute left arm pain may be caused by a broken bone. The most common causes of fractures are falls, accidents (such as car or motorcycle accidents), and sports-related injuries. In addition ...
It is also under investigation whether the injection of bupivacaine into extraocular muscles is of possible therapeutic use for treating some forms of strabismus, be it alone or in combination with botulinum toxin. Bupivacaine is a local anaesthetic known to cause considerable myotoxicity and neurotoxicity. Its injection into muscle tissue ...
