Operating principles of laser surgery for glaucoma

Principle of glaucoma surgery: filtering surgery (commonly used are trabeculectomy, subscleral bite, scleral iris embedding and scleral cautery filter, etc.). ): The purpose is to establish a new extraocular drainage. It is suitable for chronic angle-closure glaucoma with extensive adhesion of the angle of the room. The use of mydriatic can not control the intraocular pressure, C value.

Treatment. ① Laser treatment of glaucoma: This is a great progress in the treatment of glaucoma. Laser iris drilling replaces periiridectomy, and laser trabeculoplasty provides a means for the treatment of open-angle glaucoma, avoiding the surgical treatment of a large number of patients. ② Operation: The trabeculectomy was improved in many aspects, especially the application of 5-Fu, mitomycin and other drugs after filtration to reduce the scar formation of filtration channel, and the surgical effect was greatly improved. Filtering surgery combined with cataract extraction and intraocular lens implantation has achieved good clinical results. Phacoemulsification and filtration surgery are carried out at the same time, which makes glaucoma and cataract patients who can't be controlled by drugs get comprehensive treatment. Implantation of drainage tube under sclera provides a treatment for advanced complex glaucoma. ③ Drugs: Anti-glaucoma drugs have grown rapidly in recent years. For example, beta blockers include Macalline, Betaloc and Betagan; Adrenaline drugs such as Baomuning. Doctors can choose suitable and effective anti-glaucoma eye drops according to the general situation of patients, the mechanism of lowering intraocular pressure and the synergistic effect of drugs.

Glaucoma surgery: 1, filtering surgery (trabeculectomy, subscleral bite, iris embedding, scleral cautery, etc. ) .2. Peripheral iridectomy or laser iridectomy. 3. Glaucoma valve. 4. Separation of ciliary body. 5, reduce eye content surgery. 6. Reduce the formation of aqueous humor.
