Abstract

Purpose: Primary open-angle glaucoma (POAG) can be associated with abnormal ocular motor behavior, possibly as a compensatory strategy following visual field loss. The aim of this study was to explore the characteristics of saccadic eye movements in patients with early-stage POAG without any detectable glaucomatous visual field loss (i.e., preperimetric POAG). Methods: Binocular eye movements were explored in 16 patients with bilateral preperimetric POAG and 16 age-matched healthy controls in a cross-sectional, observational study. Visually guided horizontal prosaccades (5°, 10°, 15°, and 20° amplitude) and antisaccades (12° amplitude) were measured using infrared oculography. The latency, a..
