Glaucoma is the world's first irreversible blinding eye disease. As a big country with glaucoma, there are 21 million glaucoma patients in China, of which more than 1/4 of the number of blind people. Surgery is an important means to control intraocular pressure and prevent blindness, compared with traditional glaucoma surgery, minimally invasive and precise surgery is more conducive to improving the quality of visual quality of patients.
Recently, Professor Tang Li, head of the department of ophthalmology at West China Hospital of Sichuan University, successfully completed the first minimally invasive implantation of glaucoma drainage tube in Sichuan Province, and West China has become one of the first units in the country to carry out this operation. The patient's intraocular pressure was reduced from 24 mmHg in the case of preoperative quadruple medication to 8 mmHg on the second day after surgery, and the postoperative vision and anterior chamber depth were maintained well, and there were no obvious discomfort symptoms, the operation achieved satisfactory clinical results, and the patient has been successfully discharged from the hospital.
Professor Tang Li performed a new type of glaucoma drainage tube implantation
Professor Tang Li introduced that the operation is a new type of minimally invasive anti-glaucoma surgery. The surgical system consists of a gel holder and an implant, in which the gel holder is a flexible drainage tube prepared from collagen extracted from gelatin, only 6 mm long, with an outer diameter of 150 microns and an inner diameter of 45 microns, while the width of a hair strand is about 120 microns. Compared with the traditional trabecular resection surgery, which requires the opening of the conjunctiva and the production of a 4*4 mm size sclera flap, this minimally invasive implantation surgery only requires a tiny corneal incision of about 1.8 mm, and the implant with a pre-installed drainage tube is implanted through the anterior chamber to drain the aqueous aqueous humor, which will hardly damage the bulbous conjunctival tissue, and no suture is required after surgery, minimizing tissue trauma and postoperative complications, providing a new surgical treatment option for glaucoma patients.

Professor Tang Li pointed out that as a chronic and progressive disease, glaucoma requires early screening, early diagnosis and early treatment to avoid the adverse consequences of blindness. As one of the three important means of controlling glaucoma, surgical treatment is a hot spot in international and domestic research and development. Prior to this, the Department of Ophthalmology of West China Hospital has routinely carried out a series of new technologies for glaucoma surgery, covering the current mainstream minimally invasive surgical methods in China, which is not only in a leading position in Sichuan, but also in the forefront of the country. The successful introduction of this new minimally invasive implant will also benefit more glaucoma patients in Kawauchi and even the whole country. The use of each procedure for different types of glaucoma marks a new stage in west China glaucoma surgery into minimally invasive and precise treatment.
