To explore the efficacy and safety of minimally invasive suprachoroidal drainage for the treatment of advanced neovascular glaucoma

To explore the efficacy and safety of minimally invasive supraporcular drainage in the treatment of advanced neovascular glaucoma, and to record the various basic diseases, ocular conditions, lifestyle, inflammatory markers and other parameters of NVG patients. To compare the safety and efficacy of new surgical methods and traditional surgical methods in order to find an effective treatment for neovascular glaucoma

• Eye infection within two weeks before surgery
• Non-glaucomatous intraocular diseases that affect intraocular pressure (choroidal hemorrhage or detachment, retinal detachment, lens subluxation, thyroid eye disease, clinically significant macular edema, eye tumors, etc.)
• Visual acuity of non-study eyes < 0.05
