Visual Mapping for Tumor Resection: A Proof of Concept of a New Intraoperative Task and A Systematic Review of the Literature
2022, World NeurosurgeryCitation Excerpt :The main features of the review are summarized in Table 2. We found a total of 13 articles where VEP was used to monitor the visual function in different manners.16,17,19,30-34,36,42–45 Standard flash VEP (FVEP) with light-emitting diodes embedded in goggles or directly attached to the eyelids and the subcutaneous electrode or subdural grid recording were used in all cases.

2017, World NeurosurgeryCitation Excerpt :Another approach is the use of visual evoked potentials. In 2 patients, Curatolo et al19 demonstrated the feasibility of intraoperative monitoring of the visual cortex under general anesthesia, using visual evoked potentials with subdural electrodes and photic stimulation through closed eyelids with a strobe light. Postoperative visual field testing in both patients showed preservation of central vision, although with some reduction in peripheral fields.
Surgery for brain arteriovenous malformations (BAVMs): The role of intraoperative imaging and neuromonitoring
2016, Neurology Psychiatry and Brain ResearchCitation Excerpt :Up to present there is only one report about intraoperative visual monitoring in AVM surgery (San-Juan et al., 2011): Daniel et al. performed direct cortical recordings of VEPs generated by binocular flash light stimulation in a patient with an occipital AVM. However VEP recording so far is limited due to inconsistent results, speculated to be due to high susceptibility of signals to anesthetic drugs (Curatolo, Macdonell, Berkovic, & Fabinyi, 2000). Complications reported for intraoperative MEP recordings are rare.
Visual intraoperative monitoring of occipital arteriovenous malformation surgery
2011, Clinical Neurology and NeurosurgeryCitation Excerpt :Previously, visual intraoperative monitoring has been utilized to guide neurological procedures where the optic nerve or tract is involved using VEPs with scalp electrodes [1]. Although scalp VEPs allow real-time analysis of the overall activation of visually related cortical areas, they do not necessarily reflect what is occurring at the cortex level itself because scalp electrodes are relatively far away from the possible generator or generators of the VEP and because of the unique anatomic arrangement of the occipital cortex [1,2,4]. The generator source for VEPs appears to be located in the occipital cortex but actually comes from multiple sites, initially from the mesial occipital lobe and subsequently over the lateral occipital lobe [4].
