Predicting Success After Angle Surgery

Angle-based minimally invasive glaucoma surgery (MIGS) has become an increasingly important option for patients with open-angle glaucoma. As these procedures are adopted more widely and often earlier in the disease course, the challenge for clinicians is identifying the patients most likely to benefit from angle surgery. Several clinical features are consistently associated with more favorable outcomes, and can help frame preoperative counseling and guide procedure selection.

1

Angle-based minimally invasive glaucoma surgery (MIGS) is increasingly used for patients with open-angle glaucoma.
2

Clinical features such as baseline intraocular pressure (IOP) and medication burden are associated with surgical outcomes.
3

Combined phacoemulsification and MIGS procedures generally yield more favorable outcomes than standalone MIGS.
4

Prior selective laser trabeculoplasty (SLT) may indicate treatment-resistant glaucoma and affect MIGS success.
5

Pseudoexfoliation glaucoma (PXG) may respond better to MIGS than primary open-angle glaucoma (POAG), despite being clinically challenging.
