Minimally Invasive Glaucoma Surgery: Is It Here to Stay?

Abstract

ABSTRACTThe advent of minimally invasive glaucoma surgery (MIGS) has expanded the treatment options available for glaucoma by providing options for reducing intraocular pressure without the serious complication profile associated with incisional glaucoma surgery. MIGS devices aim to enhance aqueous outflow through the trabecular pathway or to bypass this pathway with drainage of fluid into the suprachoroidal or subconjunctival spaces. Having a wide range of glaucoma treatment options available helps tailor treatment to patients' individual intraocular pressure targets and aetiologies of glaucoma. This review will describe the categories and mechanisms of MIGS, comment on their relative efficacies, safety data, advantages and limitations and explore potential future changes in the glaucoma treatment paradigm in relation to MIGS.
