Humphrey Field Analyzer 740i — Refurbished Visual Field Analyzer with Floppy Drive & Printer
The Humphrey Field Analyzer 740i is a member of the Zeiss HFA II-i series, the automated static perimeter platform that glaucoma specialists and general ophthalmologists have relied on for decades. This refurbished Humphrey Field Analyzer 740i is configured as a standalone perimetry station: an integrated printer for on-site reports, the original floppy disk drive for data storage, and an electric table so the unit is ready to set up in a dedicated testing room. It runs the standard Humphrey threshold library, including the 24-2, 30-2 and 10-2 patterns, with Full Threshold and FASTPAC strategies, against the familiar 31.5 apostilb bowl background. For practices that want genuine Humphrey visual field results without paying for network connectivity they do not need, the Humphrey Field Analyzer 740i is a practical, proven choice.
A review in Survey of Ophthalmology (National Library of Medicine) describes threshold visual field testing on the Humphrey platform as the established standard for glaucoma diagnosis and monitoring.
Why Practices Choose the Humphrey Field Analyzer 740i
- Genuine HFA II-i platform — the same Humphrey bowl, stimulus system and report format used in glaucoma clinics worldwide, so results are directly comparable with referring physicians’ records.
- Full Threshold and FASTPAC strategies — Full Threshold for maximum precision and FASTPAC to shorten test time for routine follow-ups.
- Standard Humphrey test library — 24-2, 30-2, 10-2 and 60-4 threshold patterns plus screening tests for glaucoma, neuro-ophthalmic and functional field work.
- Integrated printer — print visual field reports at the instrument; no external printer or network setup required.
- Standalone floppy configuration — the original factory storage system, well suited to a dedicated perimetry workstation that does not need to connect to an EMR.
- Electric table included — height-adjustable so patients of every size can be positioned comfortably at the chinrest.
- Short learning curve — technicians already trained on any Humphrey perimeter can run the 740i on day one.

Clinical Applications
- Glaucoma diagnosis and staging — 24-2 and 30-2 threshold testing to detect and document glaucomatous field loss.
- Glaucoma progression monitoring — repeatable serial fields for patients on established therapy.
- Central field assessment — 10-2 testing for advanced glaucoma and macular-area defects.
- Ocular hypertension baseline — baseline perimetry for patients with elevated IOP and normal fields.
- Neuro-ophthalmic field defects — documentation of hemianopic, quadrantic and other neurological field loss.
Who This Is For
- General ophthalmology practices that need an affordable, dedicated Humphrey perimeter with on-site printing.
- Glaucoma practices adding a second perimeter to handle high testing volume.
- Satellite and rural clinics where a standalone station without network dependency fits the workflow.
- Practices replacing an older perimeter that want the HFA II-i platform at a lower entry cost than USB-equipped models.
