[INTERVENTIONAL GLAUCOMA - A SHIFT IN THE TREATMENT PARADIGM].

Glaucoma is a progressive optic neuropathy and is the leading cause of preventable irreversible blindness worldwide. Glaucoma causes progressive visual field loss and can have significant implications on the patient's quality of life. Lowering intraocular pressure (IOP) is the only treatment proven to prevent vision loss from glaucoma. It is achieved using medication, laser treatment and surgery. The treatment paradigm of glaucoma has been one whereby surgical intervention has been left for advanced cases due to a variety of reasons, mainly concerning safety and long term success. The past two decades have seen a paradigm shift towards earlier IOP lowering interventions using a wide array of different technologies in the laser and surgical spaces. This review aims to understand the background to this paradigm shift, its necessity, and its potential impact on the vision and life of glaucoma patients.
