Tag Archives: disease of optic nerve is formed


Strabismus is characterized by a deviation of eyes (one or two) from the central axis. Eyes thus look in different directions. The view can’t be focused on a certain subject. More often strabismus develops at two – three-year-old children when joint work of both eyes is formed.

Strabismus can result from inflammatory or tumoral lesions of eye muscles, injuries and infections of brain, wrong compensation of visual impairments, congenital diseases and birth trauma, the excessive exercises and mental stresses.

There is a concomitant and paralytic strabismus. In case of concomitant left and right eyes squint in turn, size of their deviation from the central axis is identical. Paralytic strabismus arises at injury of oculomotor muscles or disease of optic nerve. One eye (not affected) squints. Sick eye when examining a subject badly moves, not affected eye moves on the increased angle.

Strabismus can meet be convergent (the eye moves to the nose that is usually combined with hyperopia); divergent with eye deviation to the temple (more often it is combined with myopia); vertical when the eye deviates down or up.

The patient is disturbed by doubling in eyes, headache and giddiness. He sees a flat image instead of 3D, in the squinting eye visual acuity goes down.

Treatment of strabismus is begun as soon as possible, illness does not pass independently. Begin with correction of disturbances of vision. To the child puts on glasses which should be worn till strabismus symptoms decrease.

The surgery is shown at paralytic strabismus or at non-effective conservative treatment of concomitant strabismus.
