Augmentation of Aqueous Outflow After Trabecular MIGS in Primary Angle Closure Glaucoma Demonstrated by Aqueous Angiography

Minimally invasive glaucoma surgeries (MIGS) targeting the trabecular meshwork are emerging as a new modality in the management of primary angle closure glaucoma (PACG). Aqueous angiography (AA) allows in vivo, real-time assessment of conventional aqueous humor outflow (AHO) using tracer dyes. Herein, we discuss a novel case of AA demonstrating changes seen in AHO post-trabecular MIGS in a PACG patient. This case provides evidence that supports the hypothesis of using trabecular MIGS in treating PACG patients and encourages further research to innovate and study the efficacy of trabecular MIGS in the management of primary angle closure disease.
