Description
Humphrey Field Analyzer 750i — Refurbished HFA II-i Visual Field Analyzer (Floppy Disk)
The Humphrey field analyzer 750i is the definitive instrument for automated perimetry in glaucoma care — the standard against which all other visual field analyzers are measured, and the instrument that ophthalmologists and optometrists worldwide specify when selecting a perimeter for their practice. This refurbished Humphrey field analyzer 750i delivers full SITA Standard, SITA Fast, and full threshold perimetry in the proven HFA II-i platform. This unit is the Floppy Disk version — it uses the 3.5″ floppy disk drive for patient data storage and transfer. This is the standard original data transfer method for this HFA generation; patients with older practice management workflows or standalone HFA setups often prefer this version.
Clinical evidence published by the National Library of Medicine identifies standard automated perimetry with the Humphrey Field Analyzer as the primary functional test in glaucoma — confirming SITA-based threshold perimetry as the accepted method for detecting visual field loss, staging disease severity, and monitoring progression in glaucoma suspects and confirmed glaucoma patients.
What’s Included
- Humphrey HFA II-i 750i visual field analyzer (Floppy Disk version)
- Patient response button
- Power cables and accessories
- 6-month Digital Eye Center warranty
Key Features
- SITA Standard and SITA Fast perimetry — the Swedish Interactive Thresholding Algorithm delivers faster, more comfortable visual field testing with sensitivity equivalent to full threshold; SITA Fast for high-volume or fatiguing patients, SITA Standard for highest diagnostic accuracy
- Glaucoma Hemifield Test (GHT) — compares superior and inferior hemifield point clusters against age-matched normative data; the GHT classification (within normal limits, borderline, outside normal limits) is on every Humphrey field report
- Pattern Deviation probability maps — point-by-point comparison to age-corrected normative database; identifies localized scotomas independent of generalized sensitivity depression
- Guided Progression Analysis (GPA) — event-based progression analysis comparing serial fields to baseline; identifies statistically significant change at individual test points for glaucoma progression detection
- Full HFA II-i test pattern library — 24-2, 30-2, 10-2, 60-4, Esterman, and custom test patterns for all clinical applications from routine glaucoma monitoring to neuro-ophthalmic assessment
- Floppy disk data transfer — 3.5″ floppy disk drive for patient data storage; the original HFA data transfer method, compatible with legacy HFA-based practice workflows
- Refurbished at $7,600 with 6-month warranty — full HFA 750i clinical capability at refurbished pricing
Clinical Applications
- Glaucoma visual field diagnosis, staging, and progression monitoring
- Neuro-ophthalmic visual field assessment with full pattern library
- Ocular hypertension surveillance and conversion monitoring
- Pre- and post-operative visual field documentation
