PTS 925
Essilor
Automated Perimeter
The Essilor PTS 925 is a compact automated perimeter designed to provide comprehensive visual field testing while making efficient use of clinical space.
Its wide testing range extends up to 170° horizontally with fixation shift, supporting both central and peripheral visual field assessment. A broad selection of screening, threshold and specialised testing strategies allows practitioners to tailor examinations to different clinical requirements.
Integrated gaze tracking, blink monitoring, blind-spot testing and V-Eye™ virtual eye-position monitoring help support fixation control throughout the examination. Patient response timing can also adapt to examination speed, while voice guidance helps support a more streamlined testing experience.
For ongoing monitoring, the PTS 925 includes result comparison and Defect Progression Analysis (DPA™), enabling practitioners to evaluate visual field changes over time.
