Résumé : L'impotence oculomotrice résulte soit d'une altération du muscle lui-même, soit d'une bride périmusculaire entravant le jeu musculaire normal.Môts-Clés : Strabismes, impotence musculaire
Summary : Mechanical restrictions of the eye movements result
either from a muscular disability or from an extra muscularleash.
In the first case, a muscle may be unable to relax because of a contracture or a
shortness, or to contract because of a laxity or an insufficient tension. In the second
case, the leash may be direct and prevent the muscle from relaxing or inverse and prevent
it from contracting normally.
Mechanical restrictions may be congenital (muscular fibrosis, Stilling-Duane syndrom), or
acquired (Basedow-Grave disease, myositis, high myopia, post-surgical, post-orbital
trauma), or associated with othermuscular desorders (concomitant or paralytic strabismus).
The treatment is surgical: it consist to recess a tight muscle or resect or tuck a loose
one, and eventually, in a second surgery, to damp the controlateral synergist or
antagonist.
Key Words : Strabismus, mechanical restrictions
