title: [Active or postural prisms].
abstract: Oculomotor visual input of the postural system can be modified with a small powerful prism from 1 to 4 dioptries. The determination of features acting on postural tonus through visual and oculomotor input is difficult. It is necessary to examine postural and oculomotor consequences of each optical correction.
