Zeiss Cirrus 4000 OCT — Used SD-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 OCT 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 Windows 10, this unit offers an extended service lifespan and continued software compatibility at a significantly lower price point than the Cirrus 500 or 5000.

The National Library of Medicine confirms that retinal nerve fiber layer thickness measured by optical coherence tomography is a validated biomarker for differentiating glaucoma patients from disc suspects — establishing RNFL OCT analysis as the clinical standard for glaucoma documentation and the primary use case for the Zeiss Cirrus 4000.

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 across 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 in managed care.
• 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.
• Familiar Cirrus workflow — Identical software interface to the Cirrus 500 and 5000; staff move between instruments without retraining.

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 AMD, 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 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 documentation rigor required for co-management and specialist reporting.
• Optometry practices entering OCT imaging — The Cirrus platform and normative data are accepted across major co-management frameworks; the Cirrus 4000 is the most cost-effective entry into proven SD-OCT.
• Practices upgrading from time-domain OCT — 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 zero retraining for existing staff.
• Budget-conscious buyers who want Cirrus reliability — Same Zeiss imaging optics and software architecture as the Cirrus 500/5000 at a fraction of the price.
