Abstract

Glaucoma is a degenerative ocular condition characterized by irreversible vision loss from damage to the optic nerve. This is usually secondary to increased aqueous production or impaired aqueous outflow, resulting in increased intraocular pressure (IOP). Aqueous outflow is managed by the trabecular meshwork and Schlemm’s canal, although secondary pathways may also be involved.1 Injury to the nerve is permanent, and interventions are primarily aimed at slowing the rate of progression. While eye drops and laser procedures are first-line measures to lower IOP, more persistent or severe etiologies require surgical treatment to preserve sight.2 In recent years, advancements in glaucoma surgery have minimized the operative risk involved while improving visual outcomes in the affected population.
