The visual field is the backbone of glaucoma monitoring, and the perimeter you choose shapes your chair time, your progression decisions, and how easily referral partners can read your results. This guide compares the three perimetry platforms optometrists most often weigh — the ZEISS Humphrey Field Analyzer, the Haag-Streit Octopus, and Frequency Doubling Technology (FDT/Matrix) — and scores them for a real glaucoma workflow.

What to Look for in a Perimeter

  • Test strategy: SITA and SITA Faster (Humphrey) and comparable Octopus strategies cut test time while preserving accuracy — the biggest driver of daily throughput.
  • Progression analysis: reliable event- and trend-based progression software (GPA, EyeSuite) is what turns a series of fields into a defensible clinical decision.
  • Normative database and interoperability: a large normative database and printouts your referral network recognises matter for co-management.
  • Screening vs threshold: FDT/Matrix is fast and sensitive for screening; full threshold SAP is required to monitor established glaucoma.
  • Footprint and cost: screening perimeters are compact and affordable; bowl perimeters need space and a larger budget.

How to Choose

If you monitor established glaucoma and want the reference standard everyone can read, the Humphrey HFA3 is the default. If you want a full-field alternative with kinetic testing and flexible software, the Octopus is a strong choice. If your priority is fast, portable screening to catch early loss and triage referrals, FDT/Matrix earns its place alongside — not instead of — a threshold perimeter. Trial each with your own patients and confirm the progression software and printout formats fit your co-management network.

The 3 best options, reviewed

1

ZEISS Humphrey Field Analyzer 3

8.8/10

Best for: Any practice that wants the reference-standard visual field for glaucoma monitoring.

Standout feature: The clinical reference standard, with SITA test strategies and Guided Progression Analysis.

The ZEISS Humphrey Field Analyzer 3 (HFA3) is the reference standard for standard automated perimetry. Its SITA (and faster SITA Faster) strategies cut chair time while its Guided Progression Analysis and large normative database make glaucoma progression decisions defensible and universally readable by referral partners. For most practices it is the safe, interoperable choice.

Features 40% 9.3
Ease of use 30% 8.6
Value 30% 8.3

Pros

  • Clinical reference standard for SAP
  • SITA / SITA Faster reduce chair time
  • Guided Progression Analysis for glaucoma
  • Universally readable printouts

Cons

  • Premium pricing
  • Larger footprint than screening perimeters

Haag-Streit Octopus

8.5/10

Best for: Practices wanting a strong Humphrey alternative with full-field testing and cluster analysis.

Standout feature: Full-field static and kinetic perimetry with EyeSuite trend and cluster analysis.

The Haag-Streit Octopus range (600 and 900) is the leading alternative to Humphrey, offering both static and kinetic perimetry, a true full-field option, and EyeSuite software with cluster-trend progression analysis. It can even print Octopus and HFA-style outputs, easing transition for practices moving from Humphrey.

Features 40% 8.9
Ease of use 30% 8.2
Value 30% 8.2

Pros

  • Full-field static and kinetic perimetry
  • EyeSuite trend and cluster analysis
  • Can output HFA-style printouts
  • Strong build and optics

Cons

  • Smaller installed base than Humphrey
  • Learning curve moving from HFA

ZEISS FDT / Matrix

8.3/10

Best for: Practices wanting fast, portable glaucoma screening rather than full threshold monitoring.

Standout feature: Frequency-doubling technology detects early glaucomatous loss quickly in a compact unit.

Frequency Doubling Technology perimetry — now the ZEISS Matrix — uses a flickering-grating stimulus that is sensitive to early glaucomatous damage and fast to run, in a compact, affordable unit. It is excellent for screening and triage but is not a replacement for full threshold SAP when monitoring established glaucoma.

Features 40% 7.8
Ease of use 30% 8.8
Value 30% 8.6

Pros

  • Fast, patient-friendly screening
  • Sensitive to early glaucomatous loss
  • Compact and affordable
  • Low chair time

Cons

  • Screening tool, not full threshold monitoring
  • Less granular than SITA threshold fields

Frequently asked questions

The ZEISS Humphrey Field Analyzer 3 is the clinical reference standard and the default choice for monitoring glaucoma, thanks to SITA test strategies and Guided Progression Analysis. The Haag-Streit Octopus is the strongest full-field alternative, and FDT/Matrix perimetry is the best fast screening option for early detection and triage.
No. Frequency Doubling Technology (FDT/Matrix) is a fast, sensitive screening test that is excellent for detecting early glaucomatous loss and triaging patients, but it does not provide the full threshold sensitivity map needed to monitor established glaucoma over time. Most practices use FDT for screening and a threshold perimeter such as the Humphrey HFA3 for ongoing monitoring.
SITA (Swedish Interactive Thresholding Algorithm), and the faster SITA Faster, are ZEISS Humphrey test strategies that shorten a threshold visual field test while maintaining accuracy. Shorter tests mean less chair time, better patient cooperation, and more reliable results, which is why SITA is a major reason the Humphrey remains the reference standard.
Progression analysis is most reliable when performed on the same platform, because normative databases and algorithms differ between manufacturers. The Haag-Streit Octopus can produce HFA-style printouts to ease co-management, but if you are actively tracking a glaucoma patient's progression, it is best to keep them on one perimeter family and establish a fresh baseline if you change systems.
