Ophthalmic treatments


It is the most common surgical procedure in the world to control glaucoma. Glaucoma may be performed open or closed angle. It is performed under local anesthesia (retrobulbar) and sedation. It involves establishing communication between the anterior chamber and the subconjunctival space through a surgical fistula regulated by a sutured scleral permitting the flow of aqueous humor. Antifungal drugs (mitomycin, 5-fluorouracil) and anti-VEGF drugs are used to prevent excessive scarring of the fistula and maintain regular filtration over time. Variations of this technique have incorporated associated implants such as Express.
