Zeiss Humphrey Matrix 715.*
The Matrix Perimeter utilizes Frequency Doubling Technology. It represents a significant breakthrough in visual field testing by combining detection of early visual field loss and basic glaucoma management tools.
Like the Humphrey FDT Perimeter, the Matrix doubles as an in-office visual field screener with 35 second supra-threshold testing. It tests at 69 locations to characterize visual field defects and facilitate accurate diagnoses.
