Dear Editor,

Cataract surgery alone is known to be beneficial in angle closure glaucoma with more than modest intraocular pressure (IOP) reduction and widening of the anterior chamber angle (ACA) [1]. However, this may not be true in all mechanisms of angle closure and persistence of plateau is known to occur in plateau iris syndrome (PIS) [2]. Of the currently available surgical modalities, only the combination of endocycloplasty with phaco (phaco-ECPL) is capable of delivering an anatomic change in the angle in PIS [3].

We propose to demonstrate change in angle recess via intra-operative anterior segment optical coherence tomography (iASOCT) during phaco-endocycloplasty, post phaco alone and subsequently post phaco-ECPL. Until recently, iASOCT was synonymous with lamellar keratoplasty and iOCT with retinal surgery [4], but its use in the anterior segment is constantly evolving [5, 6, 7].

We conducted a study where consecutive subjects with PIS, documented by gonioscopy and ultrasound...
