This module reviews terminology and indications for peripheral iridotomy (PI) briefly, and then focuses on management of the patient whose angles remain narrow despite a successful PI. The mechanisms that cause this are explored, following by treatments for each. Particular attention is paid to lens-based surgery and ancillary techniques including phacoemulsification, goniosynechialysis, iridoplasty and endocycloplasty. Management of specific challenges encountered during lens removal for angle closure are discussed, including low endothelial cell counts, zonulopathy and intraoperative malignant glaucoma. Illustrative cases and discussion are used to elucidate and reinforce the clinical approach to treatment decisions in angle closure after successful PI.
