If after orthoptic therapy eye deviation remains, strabismus surgery is requested. Its is a treatment that should be done in local or general anaesthesia, and consists in operating extraocular muscles (those that control eye movements).
Most common treatments are:
– Recession: the muscle is detached from the surface of the eye and reattached further back from the original insertion in order to weaken its strength;
– Resection procedure: it strengthens extraocular muscle function by reattaching a muscle to the eyeball at the original insertion after a portion is removed. This procedure strenghtens the muscle function.
With recession and resection, the action of extraocular muscles is reduced or strengthend and, in this way, there is a surgical correction of strabismus.
