Optimal eye movement strategies: a comparison of neurosurgeons gaze patterns when using a surgical microscope.

Background: Previous studies have consistently demonstrated gaze behaviour differences related to expertise during various surgical procedures. In micro-neurosurgery, however, there is a lack of evidence of empirically demonstrated individual differences associated with visual attention. It is unknown exactly how neurosurgeons see a stereoscopic magnified view in the context of micro-neurosurgery and what this implies for medical training.

Analysis of disruptive events and precarious situations caused by interaction with neurosurgical microscope.

Background: Developments in micro-neurosurgical microscopes have improved operating precision and ensured the quality of outcomes. Using the stereoscopic magnified view, however, necessitates frequent manual adjustments to the microscope during an operation.

Method: This article reports on an investigation of the interaction details concerning a state-of-the-art micro-neurosurgical microscope.
