Strabismus is a very common ophthalmological condition in which the eyes are separated to the sides. There are many causes of strabismus, including congenital genetic factors, acquired trauma, and nerve paralysis of the eye. All of these causes can lead to a shift in the position of the eye, resulting in the eye being separated to the sides. In general, after the occurrence of this performance, it is necessary to go to the hospital as soon as possible to improve the examination related to strabismus, including visual acuity examination, eye position examination, and eye movement examination, according to which the specific cause and severity of strabismus can be understood. For the treatment of this condition, surgery is still the main treatment. The principle of surgery is relatively simple, which is to artificially adjust the starting and ending points of the extraocular muscles to adjust the eye position, so that the eye is in a normal position again.
