[Use of nerve division in oculomotor paralysis]

Sectors have a double interest in an extraocular muscle palsy: to avoid the diplopia and to aid the reeducation of palsied muscles. Patient can alternatively wear the two types of glasses with sectors. Authors decrease sector's size when motility improves. They are stopped if regression, and in other cases, patients can wait surgical time with maximum comfort. Clinical examples are presented: VI, III and IV cranial nerve palsies and generalized diplopia.
