Closed angle glaucoma can be treated by iris laser perforation and trabeculectomy. 1. Iris laser perforation: Aiming at the peripheral iris area, a powerful beam with a very small spot is used to cauterize or penetrate the iris tissue, creating a hole in the peripheral part of the iris, so that the aqueous humor of the anterior and posterior chambers can circulate to achieve the purpose of lowering the intraocular pressure. 2. Trabeculectomy: A new aqueous drainage channel is established at the corneal rim to drain the aqueous from the anterior chamber to the sub-bulbar conjunctival space to be absorbed by the surrounding tissues, and the functional laminae cover the drainage opening to restrict the excessive outflow of aqueous, which can reduce the postoperative low intraocular pressure, shallow anterior chamber, and the concomitant complications to a certain extent. Suffering from closed-angle glaucoma, you need to go to the hospital for examination in time and follow the doctor’s advice to choose the most suitable treatment.
