Strabismus is a relatively common disease that affects about 4-5% of the world population. It is a condition in which the eyes are aligned in incorrectly and are not oriented in the same direction: an eye while fixing an object, the other can be directed inside, outside, top, or bottom.
The disease can occur at any age.
What is strabismus?
Strabismus is the digression of the visual axes caused by the poor functioning of the neuromuscular structures that control movement of the eyeballs.
Strabismus can be of various shapes, intermittent or constant over time, and mainly affect only one eye, or be alternating.
If it was not diagnosed in time in the child, strabismus can help determine a significant permanent reduction of visual acuity (amblyopia).
In adults, the symptoms of an altered indicator muscles in a coordinated operation designated to eye movement, is double vision (diplopia).
What causes strabismus?
The causes of strabismus may differ depending on the age of onset of disturno:
neurological disorders such as cerebral palsy origin or paresis of the eye muscles
eye diseases (cataracts, ptosis, etc.)
Strabismus in children is defined as “essential” when the causes are not detectable.
In adulthood, the dependent neuro-motor apparatus modifications in charge to coordinate the movements of the eyeballs can be restrictive nature (the most common causes lie in thyroid disorders and high myopia), non-paralytic (such as failure of childhood strabismus ) and paralytic. Among the paralytic nature causes of strabismus may be part of the cranial trauma, vascular or infectious diseases, degenerative diseases of the central nervous system, diabetes.
What are the symptoms of strabismus?
The symptoms related to strabismus may be:
Photophobia (discomfort caused by light)
Sometimes head tilt
double vision (diplopia)
The findings useful to diagnose strabismus are:
orthoptic evaluation and subsequent study of ocular motility
prismatic tests for diplopia (including, usually, in the visit orthoptic)
For strabismus problems regarding each age group is practiced strabismus surgery using the most innovative method called MISS (Minimally Invasive Surgery Strabismus) which constrain the surgical trauma through the use of conjunctival openings of a few millimeters, minimizes up to eliminate totally annoying problems of the post-intervention such as soreness, reddened eyes, swollen eyelids, however with the usual perdurerebbero method for a few weeks.
Interventions for the treatment of strabismus and diplopia the correction can be implemented both in local anesthesia, general anesthesia.
