Strabismus
Strabismus surgery on the extraocular muscles to correct strabismus, the misalignment of the eyes!! Strabismus is a condition in which the eyes do not properly align with each other when looking at an object. The eyes point in different directions when looking at an object. The condition may be present occasionally or constantly If present during a large part of childhood, it may result in amblyopia or loss of depth perception. If onset is during adulthood, it is more likely to result in double vision Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma or infections. Risk factors include premature birth, cerebral palsy and a family history of the condition. Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia where they are vertically misaligned. Diagnosis may be made by observing the light reflecting from the person's eyes and finding that it is not centered on the pupil. Another condition that produces similar symptoms is a cranial nerve disease. Strabismus surgery loosens or tightens eye muscles, which changes the alignment of the eyes relative to each other.
