Intraoperative Fluorescence With Augmented Reality

The treatment group will consist of patients who require a medically necessary craniotomy. If an investigator deems that it will be useful to see blood vessels better with indocyanine green (ICG) videoangiography (VA), patients may be consented for the use if ICG VA using augmented reality (GLOW800). This will not add additional time or risk to their surgery

This is a standard medication which can be given IV during a surgery to better visualize blood vessels under the microscope
