Humphrey 750i Visual Field Analyzer — Refurbished Automated Perimeter

The Humphrey 750i visual field analyzer is Zeiss’s full-featured automated static perimeter — a bowl-type perimeter running SITA Standard, SITA Fast, and SITA SWAP algorithms across the full range of clinical test patterns including the 24-2, 30-2, 10-2, 60-4, and Esterman functional field tests. This refurbished Humphrey 750i (HFA II-i series) includes USB connectivity for direct integration with Zeiss FORUM and electronic medical record systems, plus an onboard integrated printer for immediate hard-copy output. SITA Standard and SITA Fast deliver reliable threshold estimates in approximately half the time of Full Threshold testing, with SITA SWAP available for blue-on-yellow short-wavelength automated perimetry in early glaucoma detection. Stimulus sizes I through V are selectable for specialized protocols. Available refurbished at $8,075 with a 6-month Digital Eye Center warranty — full Humphrey automated perimetry capability at refurbished-equipment pricing.

Research published in Eye identifies the Humphrey Field Analyzer with SITA Standard automated perimetry as the reference standard for glaucoma visual field testing — the clinical benchmark against which newer portable and remote perimetry devices are compared in case-finding studies worldwide.

Why Practices Choose the Humphrey 750i Visual Field Analyzer

• SITA Standard, SITA Fast, and SITA SWAP — all three algorithms included — SITA Standard delivers the gold-standard threshold estimate for glaucoma monitoring; SITA Fast cuts testing time approximately in half for patients with poor fixation or fatigue; SITA SWAP enables blue-on-yellow short-wavelength perimetry for detection of early glaucomatous loss before conventional white-on-white perimetry detects it
• Full clinical test pattern library — 24-2 central field for glaucoma staging and follow-up; 30-2 extended central field; 10-2 central 10° testing for advanced glaucoma and macular disease; 60-4 for peripheral field screening; Esterman binocular functional field for driving fitness and disability assessment; Central 40 and screening patterns also available
• USB connectivity (Gen USB) — direct EMR and FORUM integration — the Gen USB upgrade provides native USB data export from the 750i; test data transfers directly to Zeiss FORUM Glaucoma Workplace, EMR systems, and other VF management platforms without floppy disk or manual data entry
• Integrated printer — immediate hard-copy output — onboard printer produces the standard Humphrey single-field analysis, GHT, and STATPAC printouts at the instrument without a separate print station; important for paper-based workflows and patient file documentation
• STATPAC statistical analysis — STATPAC compares each result to a normative age-corrected database; GHT (Glaucoma Hemifield Test) and Mean Deviation, Pattern Standard Deviation, and Visual Field Index outputs are standard on the 750i for glaucoma staging and progression monitoring
• Goldmann stimulus sizes I–V — full protocol flexibility — standard Goldmann size III for routine perimetry; larger stimuli (IV and V) for advanced loss testing; size I for selective early loss detection; all five sizes selectable for specialized clinical and research protocols
• Background illumination 31.5 ASB — standardized photopic testing — the Humphrey bowl maintains 31.5 apostilbs background illumination to the HFA standard, ensuring results are comparable across instruments and clinical sites for multi-site practices and research protocols

Clinical Applications

• Glaucoma visual field testing — primary use — SITA Standard 24-2 is the clinical standard for glaucoma staging and follow-up; the 750i runs full SITA test batteries for newly diagnosed and established glaucoma patients; STATPAC VFI trend analysis supports progression detection over serial testing
• Glaucoma suspect monitoring — early glaucoma suspects with elevated IOP, suspicious disc, or OCT RNFL loss are monitored with serial 24-2 SITA Standard; the 750i provides the baseline and follow-up testing required for conversion detection before structural damage progresses
• Neuro-ophthalmology — visual pathway field defects — 24-2 and 30-2 SITA Standard testing characterizes hemianopias, quadrantanopias, and other neuro-related field defects for chiasmal and retrochiasmal pathway lesions; 10-2 testing maps central scotomas in optic neuritis and other anterior pathway conditions
• Advanced glaucoma — 10-2 testing — patients with severe glaucoma and field loss threatening fixation are tested with the 10-2 pattern to map remaining central field with higher spatial resolution; the 750i runs 10-2 SITA Fast and Standard for advanced glaucoma monitoring
• Functional field testing — Esterman binocular — the Esterman binocular field test assesses functional visual field for driving fitness, occupational requirements, and disability evaluation; the 750i runs Esterman binocular testing as part of its standard pattern library
• Macular disease visual field correlation — 10-2 SITA testing at the 750i characterizes central scotomas in age-related macular degeneration, macular dystrophies, and drug toxicity (hydroxychloroquine screening) where central field is the primary concern

Who This Is For

• Glaucoma-focused ophthalmology and optometry practices — the Humphrey 750i is the standard automated perimeter for glaucoma testing workflows; SITA Standard, STATPAC, and GHT outputs are the basis for glaucoma staging, treatment decisions, and progression monitoring in high-volume glaucoma practices
• Optometry practices adding visual field testing — the refurbished 750i at $8,075 delivers full Humphrey automated perimetry capability without new-instrument cost; 6-month warranty included; USB connectivity ensures compatibility with existing EMR infrastructure
• Multi-site practices and ASCs standardizing on Humphrey — the HFA II-i 750i produces STATPAC outputs that compare directly across sessions and sites; practices using FORUM Glaucoma Workplace benefit from USB data transfer for centralized result management
• Neuro-ophthalmology practices — the 750i’s 24-2, 30-2, and 10-2 SITA test battery is the standard tool for characterizing visual pathway defects and monitoring neuro-ophthalmological conditions requiring serial visual field assessment
