[Analysis of motility disturbances due to a combination of different orbital lesions by means of the synoptometer (author's transl)].

There is no clear cut symptomatology of the ocular motility in blow-out fractures. It is essentially dependant on the number of muscles involved, what muscle in particular and where the muscle in incarcerated. Besides the blow-out fracture an additional impairment of motility can occur, for example central nerve palsy or Brown's syndrome of traumatic origin. For the exact analysis of the deviation measurement from 10 to 10 degrees is essential which can best be achieved with the synoptometer of Cüppers.
