Humphrey Field Analyzer 750i — Refurbished HFA II-i Visual Field Analyzer

The Humphrey field analyzer 750i — Zeiss’s HFA II-i automated perimeter — is the instrument that glaucoma subspecialists, comprehensive ophthalmologists, and optometrists worldwide specify as the standard for threshold automated perimetry. This refurbished Humphrey field analyzer 750i runs the complete SITA algorithm set including SITA Standard, SITA Fast, and SITA SWAP, with STATPAC statistical analysis and Guided Progression Analysis (GPA) for longitudinal glaucoma monitoring. The 3.5″ floppy disk drive provides standalone data storage without USB connectivity requirements — appropriate for practices managing visual field records independently of a FORUM network. Available at $7,600 with a 6-month Digital Eye Center warranty, this humphrey field analyzer 750i delivers the full Humphrey perimetry workflow used as the reference standard for glaucoma staging, serial monitoring, and visual field progression analysis in clinical practice.

Research published in Graefe’s Archive for Clinical and Experimental Ophthalmology documenting visual field progression patterns in glaucoma patients over a 10-year national cohort confirms that serial automated perimetry — the primary clinical function of the Humphrey field analyzer 750i — remains the definitive method for detecting and quantifying glaucomatous visual field loss over time.

Why Practices Choose the Humphrey Field Analyzer 750i

• SITA Standard, SITA Fast, and SITA SWAP — complete HFA algorithm set — SITA Standard 24-2 is the gold-standard threshold test for glaucoma staging; SITA Fast reduces test time by approximately 50% for patients with limited cooperation or fatigue; SITA SWAP isolates short-wavelength pathway loss to detect glaucomatous changes before conventional white-on-white loss appears; the 750i includes all three SITA algorithms, making it the entry-level HFA II-i model with the complete perimetry toolkit
• Guided Progression Analysis — serial trend-based glaucoma monitoring — GPA compares serial 24-2 tests against a patient’s own baseline to detect event-based progression (individual point deterioration) and trend-based changes (rate of VFI decline per year); the Humphrey field analyzer 750i runs GPA analysis from stored baseline tests to support treatment timing decisions and progression documentation for medico-legal and insurance purposes
• STATPAC statistical analysis — GHT, MD, PSD, VFI — the Glaucoma Hemifield Test compares superior and inferior hemifield sectors against normative reference values for sensitivity and specificity in glaucoma detection; Mean Deviation and Pattern Standard Deviation quantify overall and localized loss; the Visual Field Index percentage-of-normal metric provides a single-number staging and trend measure widely used in clinical practice and clinical trials
• Full test pattern library — 24-2 through Esterman binocular — the 24-2 central pattern for standard glaucoma testing and serial monitoring; 30-2 extended central field for neuro-ophthalmic chiasmal and retrochiasmal defect characterization; 10-2 for advanced glaucoma with fixation threat; 60-4 peripheral screening; Esterman binocular for driving fitness and disability assessment; all patterns available in SITA Standard and SITA Fast
• Floppy disk standalone operation — no IT infrastructure required — the HFA 750i floppy disk version stores patient records on 3.5″ floppy disks and operates without USB ports, network adapters, or FORUM server connectivity; practices that manage visual field data independently of electronic health record systems can deploy the 750i without IT setup or ongoing network infrastructure
• Refurbished with 6-month warranty — complete Humphrey perimetry at $7,600 — the refurbished Humphrey field analyzer 750i at $7,600 delivers the full HFA II-i SITA algorithm set with GPA capability at a fraction of new-instrument pricing; 6-month warranty on parts and workmanship; practices adding Humphrey perimetry to a glaucoma monitoring workflow choose the 750i for the complete algorithm set at the most accessible refurbished price point

Clinical Applications

• Glaucoma staging and serial monitoring — primary application — the Humphrey field analyzer 750i runs the SITA Standard 24-2 tests used for glaucoma staging, treatment decisions, and long-term progression monitoring; GPA event and trend analysis over serial tests supports detection of clinically meaningful progression for treatment escalation or surgical planning
• Glaucoma suspect monitoring — SITA SWAP for early detection — SITA SWAP with the blue-stimulus-on-yellow-background protocol detects short-wavelength pathway loss that precedes conventional SITA Standard changes in glaucoma development; the Humphrey field analyzer 750i supports early detection protocols for patients with elevated IOP, disc hemorrhage, or suspicious optic nerve morphology without definitive conventional field loss
• Neuro-ophthalmology — visual field defect characterization — 24-2 and 30-2 SITA Standard characterize hemianopias, quadrantanopias, and bitemporal defects in chiasmal and retrochiasmal lesions; the Humphrey field analyzer 750i’s normative database and STATPAC output support documentation of neuro-ophthalmic findings for neurology and neurosurgery co-management
• Advanced glaucoma — 10-2 fixation threat assessment — patients with severe field loss threatening fixation are monitored with the 10-2 central pattern to map the remaining visual field at higher spatial resolution; the Humphrey field analyzer 750i runs 10-2 SITA Standard and SITA Fast for end-stage glaucoma monitoring and low-vision assessment documentation
• Clinical research and academic glaucoma programs — the Humphrey field analyzer is the instrument specified in glaucoma clinical trials, progression studies, and epidemiological research as the reference perimeter; institutions and academic practices using the 750i maintain the same instrument platform as the trial data against which treatment outcomes are benchmarked

Who This Is For

• Glaucoma-focused practices requiring GPA and SITA SWAP — the Humphrey field analyzer 750i is the minimum HFA II-i model with both GPA progression analysis and the SITA SWAP algorithm; practices that perform event-based and trend-based GPA monitoring alongside SITA SWAP early detection need the 750i platform rather than the 740i or 745i
• Practices preferring standalone field testing without network integration — the floppy disk configuration operates independently of IT infrastructure; appropriate for private practices and smaller clinics that manage visual field records independently and prefer a self-contained perimetry station
• Academic and research ophthalmology programs — institutions contributing to or benchmarking against glaucoma clinical trials use the Humphrey field analyzer as the specified instrument; the refurbished 750i at $7,600 provides trial-compatible perimetry for programs adding or expanding automated field testing capacity
• Ophthalmology practices adding a second visual field lane — the refurbished Humphrey field analyzer 750i at $7,600 provides a complete second perimetry station for high-volume glaucoma practices without new-instrument investment; 6-month warranty included for practices expanding their field testing throughput
