[Etiologic diagnosis of oculomotor paralysis by computerized tomography: a statistical approach. Apropos of 472 cases].

Among 4,538 neuroradiology cases gathered at the NOHC of the XV-XX, an oculomotor paralysis is the 3rd (37.65%) clinical circumstances justifying a computerized tomography (directional plane by the neuro-ocular plane or PNO). The interpretation of the investigations requires to index them in 7 groups of items, therefore a computerized access follows (cross-sorting data). The injury of the VI overcomes (39.61%) followed by the one of the III (33.68%), and the IV (6.35%). In spite of limitations, the study puts forward and debates about etiological frequencies sometimes different from those in the literature.
