Summary

Visual morbidity (visual acuity and/or visual field deficit) must be taken into account during neurosurgical procedures for lesions near the optical pathways. Part of this morbidity is due to surgical manipulation. There is no validated tool for intraoperative visual monitoring and few publications have studied this issue.

In a preliminary work based on analysis of these publications, we defined technical, anaesthetic and analytical parameters in order to optimise intraoperative visual evoked potentials monitoring. These parameters are special devices used for transpalpebral stimulation, complete intravenous anaesthesia without halogen or nitrous oxide, and pertinent analysis criteria of visual evoked potential (VEP). We suppose that these improvements will increase reliability of intraoperative VEP.

Conditions

  • Surgery
  • Optic Nerve and Pathway Injury

Interventions

DEVICE

Visual evoked potentials monitoring during neurosurgery - Vision monitor MonOpera®

Visual assessment (visual field, visual acuity, pattern visual evoked potential) are realised before and after surgery. Flash and steady state visual evoked potential are measured during the surgical procedure at different times.
