Description
Humphrey Field Analyzer 750i — Refurbished HFA II-i Visual Field Analyzer
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 — the same clinical performance that makes the Humphrey 750i the reference perimeter in published glaucoma clinical trials and the expected instrument in glaucoma specialty and comprehensive ophthalmology practices alike.
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.
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
- 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
