Abstract

Angle-closure glaucoma is a major cause of visual impairment worldwide, with Plateau iris syndrome presenting management challenges. We present a case report of a 58-year-old woman with advanced, uncontrolled angle-closure glaucoma and Plateau iris. Her history included laser peripheral iridotomy and three glaucoma medications in both eyes. Different treatments were implemented. For the eye with lower intraocular pressure, fewer peripheral anterior synechiae, and milder disease: phacoemulsification with intraocular lens implantation. For the eye with more advanced disease, a two-step approach was used: slow-coagulation transscleral cyclophotocoagulation using the double-arc protocol, followed by phacoemulsification with intraocular lens implantation 2 months later. Both eyes achieved improved visual acuity and intraocular pressure control with fewer medications, without significant complications. This case highlights transscleral cyclophotocoagulation followed by phacoemulsification as an alternative to combined surgeries in uncontrolled angle-closure glaucoma with Plateau iris, offering a simpler technique, more predictable refractive and pressure-control outcomes, and more straightforward postoperative management.
