This study is intended to evaluate the feasibility of using VisAR augmented reality surgical navigation during placement of an external ventricular drain (EVD). The investigators are interested in confirming the design of the VisAR headset is compatible with this bedside procedure.
A secondary objective of this study is to compare the accuracy of freehand EVD navigation, the current standard of care, with VisAR augmented reality surgical navigation. The intent is to demonstrate the advantages to the patient by the use/application of this next generation navigation technology.

|---|---|---|
| Determining navigation system accuracy based on anatomical location and Kakarla scoring system. | The accuracy of VisAR in placement of EVDs primary assessment will be graded based on the anatomical location of the EVD, known as the Kakarla scoring system. The Kakarla scoring system has 3 grades of accuracy of placement based on the location of the catheter tip. | During surgery |
