Intraoperative Fluorescence With Augmented Reality

Phase 4 Open Label Study Of Indocyanine Green Video Angiography (ICG-VA) And Comparative Utility Of Glow800 And FL800 Intraoperative ICG-VA Tools For Intracranial Lesions

This is a study looking at a new way to evaluate vascular problems or tumors in brain surgery patients using a standard & approved intravenous dye and augmented reality.

This is a study investigating a new technique with an approved medication (ICG or indocyanine green) and using that and a near infrared mode on a standard operating room microscope to see the information provided for vascular or neoplastic (tumor related) neurosurgical problems. The technique uses the data from the microscope and using ICG with augmented reality overlaying the data into the microscope view (this is the new process). The technique is called GLOW800.

Inclusion Criteria:

• adult patients with a brain lesion requiring surgery and for whom ICG videoangiography would be used

Exclusion Criteria:

• allergy to ICG (indocyanine green)
