Near-infrared II (NIR-II) fluorescence imaging has revealed significant potential for advancing glioma diagnosis because of its non-invasiveness, high spatiotemporal resolution, reasonable sensitivity, and deep penetration. These imaging techniques have been widely used to guide real-time glioma treatment with high accuracy and efficiency. This review summarised the applications and progress of NIR-II in guiding glioma surgery, targeted drug delivery, photoacoustic therapy, and multimodal therapy. We demonstrated the feasibility and practicality of integrating these technologies into glioma diagnosis and treatment. These technologies have great potential to improve patient prognosis further. Furthermore, this review highlights the challenges of using these technologies in future clinical studies.Keywords: near-infrared II, glioma, surgery, multimodal therapy, phototherapy
