By far the most frequent malpositions of the eyes are those on the horizontal plane, i.e. the internal (escotropia) and external (exotropia) strabismus with a strabismus angle remaining constant. Fundamentally, two different methods of operative corrections are used:
|
| - |
strengthening of a muscle by cutting short the muscle or moving its insertion towards the front of the eye
|
|
-
|
weakening of a muscle by moving its insertion towards the back of the eye.
|
Depending on the size of the strabismus angle, operations are carried out separately or in combination, on one eye or on both eyes simultaneously.
The considerably rarer complex movement disorders of the eye including the oblique and vertical eye muscles, paralytic strabismus and other kinds of strabismus with an unsteady angle of squint are not operated at Stralsund Eye Clinic.
