Comparison of angle-closure detection between automated gonioscopy and anterior-segment optical coherence tomography.

ABSTRACT:

Purpose

To investigate the concordance between angle-closure assessments based on GS-1 gonioscope images and those obtained with anterior-segment optical coherence tomography.

Study design

Retrospective clinical study.

Methods

We included 33 patients (53 eyes) who visited Chukyo Eye Clinic during 2020-2024, were suspected of having angle closure, and underwent anterior-segment optical coherence tomography (CASIA2 Advance STAR Analyzer) and GS-1 examinations. The 16-directional images captured with the GS-1 were divided into two halves, creating 32 directions, which were rearranged to correspond with those obtained via anterior-segment optical coherence tomography. Agreement between evaluations was analyzed using Cohen's κ, and the area under the receiver operating cha
