Humphrey Field Analyzer 740i — Refurbished Visual Field Analyzer with USB and Printer

The Humphrey Field Analyzer 740i is the threshold model of the Zeiss HFA II-i series, the automated perimeter that set the reference standard for glaucoma visual field testing. This refurbished Humphrey Field Analyzer 740i runs SITA Standard and SITA Fast threshold testing with STATPAC analysis, monitors fixation with Gaze Tracking and a video eye monitor, and pairs a generic USB port for data export with an integrated printer for on-the-spot printouts. It ships on an electric table, so the Humphrey Field Analyzer 740i arrives as a complete visual field station for glaucoma, neuro-ophthalmic and functional field testing.

Research in the National Library of Medicine (American Journal of Ophthalmology, 2022) examined standard reliability indices together with gaze tracking metrics in glaucoma and glaucoma suspects, showing why continuous fixation records like the ones the 740i prints alongside each field matter when judging whether a visual field result can be trusted.

Why Practices Choose the Humphrey Field Analyzer 740i

• SITA Standard and SITA Fast — Zeiss’s SITA strategies deliver threshold fields in about half the time of conventional algorithms; Full Threshold and FastPac remain available when a protocol calls for them
• Gaze Tracking on every test — unlike the entry-level 720i, the 740i includes Zeiss’s patented Gaze Tracking, which uses real-time image analysis to confirm the patient is looking at the fixation target; the gaze track graph prints with the results as a permanent fixation record
• Three layers of fixation control — Gaze Tracking works together with the on-screen video eye monitor and Heijl-Krakau blind spot monitoring, helping technicians catch unreliable responses during the test instead of after it
• STATPAC analysis at the instrument — Single Field Analysis with global indices, the Glaucoma Hemifield Test and Change Analysis across serial tests support glaucoma diagnosis and follow-up
• Generic USB and integrated printer — export patient data over USB instead of floppy disks, and print results immediately at the perimeter without a separate print station
• Custom test patterns — the 740i lets you create and store your own test patterns alongside the standard 24-2, 30-2, 10-2 and peripheral libraries
• Touch screen operation — menu and icon commands on the touch screen keep training simple for new perimetry technicians

Clinical Applications

• Glaucoma diagnosis and staging — SITA Standard 24-2 and 30-2 threshold testing with STATPAC Single Field Analysis and the Glaucoma Hemifield Test
• Glaucoma progression monitoring — serial threshold fields compared with STATPAC Change Analysis to document stability or progression over time
• Central field mapping — the 10-2 pattern for advanced glaucoma and for macular and central field concerns
• Neuro-ophthalmology — 24-2 and 30-2 fields to characterize hemianopic, quadrantanopic and other visual pathway defects
• Functional field assessment — Esterman monocular and binocular tests for driving and disability evaluations

Who This Is For

• Ophthalmology and optometry practices adding automated perimetry — a complete Humphrey station with table and printer for glaucoma care
• Practices moving off floppy-disk perimeters — the generic USB port simplifies data export compared with floppy-based HFA II units
• High-volume glaucoma practices — a second visual field lane that runs the same SITA protocols as an existing Humphrey
• Practices that need fixation documentation — Gaze Tracking printouts support reliability review on every field
