title: [Moebius syndrome : one case (author's transl)].
abstract: The Moebius syndrome is a congenital anomaly characterized by paralysis of the sixth and seventh nerves. In some instances, there may be weakness of the adductors. The other muscles are normal. Visual acuity is not affected. Other congenital defects may be associated: polydactyly, defects of the ear and of the tongue. Etiology is probably an embryonal egression, cause of aplasia of the facial and abducens nucleï. The impossibility to move the eyes laterally in either direction, points to supranucleus involvement by defective development of the medial longitudinal fasciculus. Some people suggest that a myogen disturbance should be the principal and unique etiology. No evolution. No treatment.
