ABSTRACT
Objectives: To determine the behavior of the visual cerebral cortex during the photo stimulation in the dissociated strabismus.Material and methods: We elaborated a digital cerebral mapping using the international 10-20 system with 21 electrodes and an option of a register of 32 channels with established parameters in every period (printed and with pulse monitoring) applied to two children with dissociated strabismus. We registered and evaluated the cortical response to different stimuli: luminous, hyperventilation, closing and opening of eyelids, asleep and awake; through digital electroencephalography, as well as the registering of ocular movements with electroculography and video film with infrared light.
Results: We discovered a paradoxical neuroelectrical response and the visual cerebral cortex during the intermittent photo stimulation never reported before, showing the neuroelectrical changes that occur in the dissociated horizontal deviation (DHD). We correlated these findings with the origin of the dissociated strabismus.
