Modifications in infrared intraoperative neuromonitoring camera and supports.

At my request, modifications were made to the visual oculography (VOG) camera described in the March 2008 article in this journal: "Use of an Infrared Camera to Improve the Outcome of Facial Nerve Monitoring," Am J Electroneurodiagnostic Technol 48.:38-47. The camera now has a wider and a more distant range and a clamp onto a rod.
