Zeiss Cirrus 4000 OCT – Refurbished

Post date November 2, 2020

Specifications for Cirrus 4000

The ZEISS Cirrus HD-OCT 4000 (Cirrus HD-OCT or Cirrus) enables examination of the posterior and anterior of the eye at an extremely fine spatial scale, without surgical biopsy or even any contact with the eye.

The Cirrus HD-OCT builds on and refines the retinal imaging technology first introduced with the ZEISS Stratus OCT™.

Employing the advanced imaging technology of spectral-domain optical coherence tomography, Cirrus HD-OCT acquires OCT data about 70 times faster (27,000 vs. 400 A-scans per second) and with better resolution (5 μm vs. ~10 μm axial resolution in tissue), compared to first-generation OCT technology.

Cirrus acquires whole cubes of OCT image data, composed of hundreds of line scans, in about the same time as Stratus acquires a six-line scan. You can view these data cubes in three planes, or through three dimensions, giving you access to an extensive amount of retinal image data in one scan.

Specifications for Cirrus 4000

The Cirrus HD-OCT with Retinal Nerve Fiber Layer (RNFL), Macular, Optic Nerve Head, and Ganglion Cell Normative Databases is indicated for in-vivo viewing, axial cross-sectional, and three-dimensional imaging and measurement of anterior and posterior ocular structures.

2-Phase Noise Reduction has been available since 2006 in the RTVue FD-OCT system, reducing signal noise during the scan acquisition and post-processing of the data captured. This allows for higher contrast in both the choroid and vitreous for optimum visualization of structures.

Motion Correction Technology applies proprietary algorithms to 3D data to reduce or remove artifacts caused by eye motion during scanning. 3D scans in OCT systems are the most time-consuming and prone to motion artifacts. SMARTTM MCT in Avanti allows a 3D cube of 320×320 (104 million data points) over a 12mm x 9mm area of the retina with little or no motion artifacts in most patients.

SharpVue technology provides highly detailed B-scans up to 12mm using Avanti’s 70,000 scans per second, exclusive 2-phase Noise Reduction, VTRAC real-time Tracking, 5μm tissue resolution (3 digital*), and DCI (Deep Choroidal Imaging).

Widefield 3D with Smart Motion Correction Technology processing reduces the incidence of motion artifacts common in volume scanning. Correct alignment of data improves the likelihood of accurate and repeatable analysis.

Enface viewing of 3D data allows thin retina slices to be assessed for small micro-structural changes.

Widefield Enface Reference. A specifically segmented enface view of the 320×320 (28-micron spacing) OCT fundus image provides the highly detailed fundus enface reference view for all scan types for orientation and physiological correlation.

Real-Time Tracking. Avanti’s VTRAC active eye-tracking provides the detail and clarity you need to assess the retina, monitor your patients, and track disease progression.

Retina OverVue Report. This summary report brings the NDB-linked Retina Map, Widefield reference scan, and high-resolution cross-line scan in one easy-to-read report.

Retina Trend Analysis The new Retina Map Change Analysis report provides a Trend analysis of the Foveal Thickness and Macula Volume throughout the patient visit history.

Multi-layered Enface Report Presents a user-defined sampling of segmented slices in high contrast 2D enface summed images—user-selectable default for assessment of retina surface neuro-sensory, retina pigment epithelium, and choroid.

3mm scan depth in a 12mm x 9mm volume scan visualizes structures from deep choroid well into the vitreous—an asset when documenting long axial length or high myopic eyes.

Enhanced HD Line Scan provides a high-density 12mm scan and presentation option for enhanced vitreous or choroid viewing.

Comprehensive analysis tools for assessing changes in retinal nerve fiber, optic disc parameters, and ganglion cell complex structures over time.

Retinal Nerve Fiber (RNFL) and Optic Disc.

Optovue’s robust proprietary algorithms allow for the confident assessment of the optic nerve head and Retinal Nerve Fiber. For the RNFL sampling and optic disc parameters, a comparison to an extensive normative database is provided.

A Normative Database (NDB) comparison reference is provided for the Retinal Nerve Fiber Layer, Optic Disc, and GCC (Ganglion Cell Complex), including FLV (Focal Loss Volume) and GLV (Global Loss Volume).

Ganglion Cell Complex (GCC).

GCC Analysis was introduced to eye care by Optovue in 2007. Seven years of clinical studies have shown Optovue to be the leader in developing and expanding the clinical utility of OCT technology.

Focal Loss Volume (FLV) & Global Loss Volume (GLV) are exclusive and proprietary analyses that increase the specificity and sensitivity of the GCC analysis.

Combined RNFL / GCC Change Report + TREND

The nerve fiber change summary report, with the new TREND analysis, provides the most comprehensive data presentation to simplify your evaluation process.

Proprietary algorithms determine the optic disc margin and vessel patterns to ensure reliable RNFL and optic disc change over time assessment.

TREND Analysis assesses the rate of change for Retinal Nerve Fiber and Ganglion Cell Complex structure.

No highlighting of p-value indicates no statistically significant change over time.
Light purple with black numbers indicates that the change over time is borderline statistically significant.
Dark purple with white numbers indicates that change over time is statistically significant.

The NDB Comparison summary table quickly references metrics flagged as borderline or outside normal limits.

Optic Disc Structure Analysis

High-detail structural examination of the optic disc with Cross line B-scans

Widefield Enface Mapping

Convenient and quicker assessment of orientation with RNFL and GCC results mapped to widefield enface.

TCP®: Total Cornea Power

TCP®:TotalCorneaPower enhances post-refractive IOL calculations for greater confidence in surgical outcomes.

The Cornea Power Upgrade allows the evaluation of patients with prior refractive procedures. Standard topography only calculates the front curvature and then extrapolates posterior curvature. Using the Cornea Power Upgrade option, the anterior and posterior curvatures are measured directly to obtain cornea powers.
