Changes in Iridocorneal Angle and Anterior Chamber Structure in Eyes With Anatomically Narrow Angles: Laser Iridotomy Versus Pilocarpine.

Purpose: To compare the effects of laser iridotomy (LI) and pilocarpine on iridocorneal angle and anterior chamber structure in anatomically narrow angles (ANAs).

Materials And Methods: Temporal LI was performed 90 minutes after 2% pilocarpine administration in patients with occludable ANA. Swept-source optical coherence tomography B-scans of the anterior segment were obtained at baseline, 60 minutes after 2% pilocarpine administration, and 1 week after LI.
