Humphrey Matrix 800 — Used FDT Visual Field Analyzer
The Humphrey Matrix 800 from Zeiss is a visual field analyzer built on frequency doubling technology (FDT). Instead of the white-on-white spots used by standard automated perimetry, the Humphrey Matrix 800 presents flickering, frequency-doubled sinusoidal gratings designed to pick up early functional loss. This used Humphrey Matrix 800 runs both rapid supra-threshold screening and full threshold exams, including 24-2, 30-2, 10-2, N-30 and Macula programs.
Because the Matrix tests in ambient room light, it does not need a dedicated dark room, which makes it practical for pre-testing lanes and satellite offices. Results are analyzed with the Glaucoma Hemifield Test (GHT), and fixation is controlled with video eye monitoring and the Heijl-Krakau blind spot method.
A study indexed by the National Library of Medicine combined FDT Matrix perimetry with SD-OCT to build an algorithm for improving early glaucoma detection in primary care settings.
Why Practices Choose the Zeiss Humphrey Matrix 800
- Frequency doubling technology — frequency-doubled grating stimuli built to detect the early stages of visual field loss.
- Screening and full threshold in one unit — supra-threshold screening (24-2, N-30) plus full threshold 24-2, 30-2, 10-2, N-30 and Macula tests.
- Ambient-light testing — no separate dark room required, so the perimeter can share a pre-testing room.
- Three fixation control options — video eye monitoring, Heijl-Krakau blind spot monitoring and alternative fixation targets.
- Glaucoma Hemifield Test — built-in GHT analysis to support long-term glaucoma management.
- Compact tabletop design — all-in-one unit with an operator touch screen and keyboard, about 17.4 kg.

Clinical Applications
- Early glaucoma detection — FDT screening to flag functional loss in glaucoma suspects and ocular hypertensives.
- Glaucoma follow-up — repeat 24-2, 30-2 and 10-2 full threshold tests to track visual field change over time.
- Central field assessment — 10-2 and Macula programs for defects close to fixation.
- High-volume pre-testing — quick supra-threshold screening to decide which patients need further testing.
- Neuro-ophthalmic screening — N-30 and 30-2 programs for field defects outside the glaucoma pattern.
Who This Is For
- Optometry practices adding glaucoma screening without giving up a dark room.
- Ophthalmology clinics that want a second perimeter for screening and overflow.
- Multi-location and satellite offices that need a compact, tabletop visual field analyzer.
- Screening programs running quick FDT tests on a large number of patients.
