Orbital fracture can be complicated by medial rectus muscle entrapment whic
h usually involves the anterior part of the muscle (pseudo Duane syndrome).
We describe an unusual case of isolated medial orbital wall fracture with
medial rectus entrapment. Our patient had entrapment of the posterior part
of the muscle with exotropia and limitation of adduction. This rare complic
ation must be recognized so the appropriate management could be instituted
early to avoid potential functional sequelae.
