The Humphrey Matrix Perimeter utilizes Welch Allyn Frequency Doubling Technology represents a significant breakthrough in visual field testing by combining early glaucoma detection capabilities, tools to characterize glaucoma and basic glaucoma management tools.

The Matrix doubles as an in-office glaucoma screener with 35 second supra-threshold testing, and it provides up to 69 stimuli to characterize visual field defects to facilitate accurate diagnoses.

The Humphrey Matrix Perimeter comes equipped with Glaucoma Asymmetry Test and serial field overview software for comprehensive threshold exams and charting change over time.

It is clinically validated by numerous studies. Patient friendly, the Matrix Perimeter's video eye monitoring feature simplifies patient alignment and fixation control. An eye patch isn't required and trial lenses are only needed beyond +/- 3 diopters. It includes enhanced optics for 30° FOV. The Matrix performs dependably in ambient light so there's no need to darken the room. Matrix stores your exams for historical analysis.
