Evaluation of the Perimouse Online Suprathreshold Visual Field Test for Glaucoma Screening in a Chinese Population: A Comparison with the Humphrey Field Analyzer

Purpose

To evaluate the diagnostic performance and spatial agreement of an online suprathreshold perimeter (Perimouse) compared with the Humphrey Field Analyzer (HFA) for detecting glaucomatous visual field defects. Patients and methods: In this prospective comparative study, 174 participants (283 eyes with open-angle glaucoma or healthy controls) underwent Perimouse suprathreshold program and HFA. Abnormal points (missed stimuli in Perimouse; points with P<0.5% on HFA total deviation map) were compared. Diagnostic performance was assessed using receiver operating characteristic (ROC) curve analysis. Point-wise performance used neural network-derived area under the curve (AUC) and Cohen's κ.
