Strabismus

Such a position of the eye in which their visual axes do not converge on the lockable object (under consideration).
Mowing can be one and the same eye or both alternately. Convergent squint - eyes cast to the nose, divergent - to the temple, is less common vertical component - up or down.
There are friendly and paralytic strabismus. With friendly - holds the full amount of movement of the eyeballs and does not bother doubling. This type of strabismus occurs in early childhood, the cause of his most often refractive error. In hyperopia strabismus is usually convergent, with myopia - divergent. Strabismus may be due to changes in intrauterine oculomotor apparatus or the central nervous system, as well as birth trauma. The cause of paralytic strabismus is a trauma, tumor, infection and so on. This results in partial or complete paralysis of one or more extraocular muscles. At the same time there is limited mobility of the eyeball toward the paralyzed muscles, double vision.
There is no difficulty. The easiest way to determine the presence of strabismus is as follows: the study sits at a distance of 1 meter away from you. reading lamps placed beside him. Using a handheld mirror light from the lamp is directed into the eyes. Normally reflection should be in the center of the pupil, in strabismus it will be shifted to the side. Experience can be carried out with a burning candle. To determine the cause of strabismus requires a thorough examination, including a neurologist.
When errors of refraction require painstaking treatment by an ophthalmologist. Paralytic strabismus may take after the treatment of the underlying disease. It is also used surgical approach.
