Glaucoma surgery is mainly performed to promote atrial aqueous drainage or to reduce atrial aqueous production, and the specific surgical procedures are classified as follows: 1. Internal drainage surgery, including peripheral iridectomy, iridoplasty, iridoplasty, iris laser perforation, atrial angle dissection, mucocutaneous molding, mucocutaneous dissection, laser trabeculoplasty, trabecular meshwork drainage implant surgery, etc. 2. External drainage surgery, including full scleral surgery, compound trabeculectomy, glaucoma valve stud implantation, etc. 3. surgery, compound trabeculectomy, glaucoma valve nail implantation, etc. 3, surgery to reduce atrial aqueous production, including ciliary cryosurgery, ciliary photocoagulation, high-intensity focused ultrasonic ciliary disruption surgery, etc. 4, combined surgery, such as cataract ultrasound emulsification combined with atrial angle separation, cataract ultrasound emulsification combined with trabeculectomy, anterior segment vitrectomy combined with atrial angle separation surgery, etc. Glaucoma treatment does not rely solely on surgical solution, some types of medication are the main treatment, and different types of glaucoma are suitable for different surgical methods.
