Description
Zeiss Cirrus 4000 OCT — Used Spectral-Domain HD-OCT with GPA and Windows 10
The Zeiss Cirrus 4000 HD-OCT is a proven spectral-domain OCT platform built on the same foundational Cirrus architecture trusted in glaucoma and retina practices worldwide. This used Zeiss Cirrus 4000 runs at 27,000 A-scans per second and delivers the full Cirrus protocol suite — Macular Cube 512×128, Optic Disc Cube 200×200, and HD 5-Line Raster — with Guided Progression Analysis (GPA) for serial glaucoma monitoring. Updated to run on Windows 10, it offers an extended service lifespan and continued software compatibility at a significantly lower price point than the Cirrus 500 or 5000.
Clinical evidence published in the National Library of Medicine confirms that the Zeiss Cirrus normative database — built into every Cirrus HD-OCT — provides statistically validated RNFL thickness comparisons that are foundational to modern glaucoma progression monitoring and one of the most cited reference datasets in published glaucoma research.
What’s Included
- Zeiss Cirrus HD-OCT 4000 main unit
- Integrated workstation with Cirrus software (Windows 10)
- Patient chin and forehead rest assembly
- Monitor, keyboard, and mouse
- Power and data cables
- 90-day Digital Eye Center warranty
Why Practices Choose the Zeiss Cirrus 4000
- 27,000 A-scans per second — spectral-domain acquisition speed delivers high-resolution macular and optic disc cubes with minimal motion artifact for the full Cirrus protocol suite
- Guided Progression Analysis (GPA) — detects statistically significant RNFL thinning between serial scans and generates summary progression reports; the documentation standard for glaucoma change detection
- Macular Cube 512×128 — dense macular sampling for accurate retinal thickness mapping, AMD drusen analysis, and diabetic macular edema monitoring
- Optic Disc Cube 200×200 — full optic nerve head quantification with rim area, cup-to-disc ratio, and RNFL thickness clock-hour map
- Cirrus normative database — age-stratified RNFL and macular thickness normative values from the most-referenced Cirrus dataset in published glaucoma literature
- Windows 10 updated — extended system life, continued software compatibility, and improved reliability versus older operating systems
- Established Cirrus software workflow — familiar to optometrists and ophthalmologists trained on any Cirrus platform; zero learning curve for practices already using Cirrus instruments
Clinical Applications
- Glaucoma monitoring and progression detection — GPA-powered serial RNFL analysis with statistical change flags; the standard workflow for managed care glaucoma documentation
- Macular disease management — retinal thickness maps for age-related macular degeneration, diabetic macular edema, epiretinal membrane, and vitreomacular traction
- Optic nerve head analysis — quantified rim area, C/D ratio, and RNFL deviation maps for glaucoma suspects and ocular hypertension patients
- Retinal layer segmentation — delineates individual retinal layers for neuro-ophthalmology applications including optic neuritis and MS-related RNFL thinning
- Second-unit expansion — adds high-volume OCT capacity at a used price, freeing the primary unit for complex or new patient imaging
Who This Is For
- Ophthalmology practices with active glaucoma populations — GPA and the Cirrus normative database provide the clinical documentation rigor required for co-management and specialist reporting
- Optometry practices entering OCT imaging — the Cirrus platform and normative data are accepted across the major co-management frameworks; a used Cirrus 4000 is the most cost-effective entry into proven SD-OCT
- Practices upgrading from time-domain OCT — the Cirrus 4000 delivers a meaningful step up in resolution, scan speed, and analysis software from older Stratus OCT instruments
- High-volume practices adding a second OCT lane — identical software workflow to the Cirrus 500 and 5000 means staff can move between instruments without retraining
- Budget-conscious buyers who want Cirrus reliability — the same Zeiss imaging optics and software architecture as the more expensive Cirrus 500/5000 at roughly half the price
