Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Fluorescein is a dye agent that can be injected through an intravenous line. It has been shown to help tell the difference between brain tumor tissue and normal brain tissue when it is used together with a specialized filter on a microscope in the operating room. The investigators plan to study the use of fluorescein in the removal of brain tumors at a low dose.
