All new Models 5000 and 500
Today, there’s a CIRRUS™ that can help your practice manage the challenges you face on a daily basis. The new CIRRUS HD-OCT models 5000 and 500 are specifically designed to deliver a carefully constructed set of sophisticated applications that build upon one another to deliver rapidly-evolving diagnostics for multiple patient populations. CIRRUS HD-OCT 5000 is the clinical powerhouse with FastTrac™ and sophisticated analyses for the busy advanced care practice. CIRRUS HD-OCT 500 is the essential OCT with the technology to power today’s comprehensive practice.

CIRRUS for Retinal Disease
With the new FastTrac retinal tracking system, precise macular thickness analyses, Fovea Finder™, detailed layer maps and more than 100 B-scans at your disposal, CIRRUS provides the framework to comprehensively assess your patient’s retinal condition. CIRRUS data cubes are registered with data from prior visits after the scan is acquired. This enables side-by-side visualization of the same location on the retina for each visit. CIRRUS compares measurements from the current and prior visits to provide a thickness change map that helps you determine next steps for your patient. 3-D cubes and Advanced Visualization™ can be used for pre-operative planning for VRI disorders. For dry AMD, CIRRUS helps you monitor pre-conversion patients today and prepare for tomorrow’s dry AMD therapy.

CIRRUS for Glaucoma
No other company offers a more complete suite of integrated glaucoma diagnostics. CIRRUS is the HFA's perfect companion for glaucoma management. Today's CIRRUS glaucoma applications include RNFL, ONH and angle assessment as well as the new Ganglion Cell Analysis (GCA). When ONH and RNFL status are indeterminate, GCA can sharpen the picture. With CIRRUS angle imaging and central corneal thickness measurements, you have the world’s standard-setting comprehensive tool for glaucoma structural assessment. Guided Progression Analysis™ (GPA) provides a powerful tool for determining change for RNFL and optic nerve head parameters.

Great Images & Dense Data Cubes

Brilliant, detail-rich B-scans plus the power of the CIRRUS cube let you visualize and quantitate pathology without extra scans.


Spectacular Images

With world-class ZEISS optics and knowledge from over a decade of experience in OCT, CIRRUS captures spectacular images of both the retina and anterior segment. Visualization and caliper measurements of the deeper layers are also facilitated by Enhanced Depth Imaging (EDI) , now available with the HD Raster scan.

The Power of the Cube

CIRRUS captures a highly dense cube over a 6 x 6 mm region - the data is used for both visualization and analysis. How this helps you:

  • Spot small areas of pathology. Tightly spaced B-scans, either 30 or 47 μm apart, in the cube ensure that small areas of pathology are imaged. For reference, a human hair is about 40-120 μm in diameter.
  • Visualize the fovea. Scans that are spaced further apart than in the CIRRUS cube may miss the central fovea.
  • Fuel for analysis. Millions of data points from the cube are fed into the Zeiss proprietary algorithms for accurate segmentation, reproducible measurements and registration for change analysis.
  • Take the pressure off the operator. As long as the scan is roughly placed about the fovea or optic nerve, the software automatically centers the measurements after the capture.
  • See the tissue from different perspectives. View the cube data from all angles, with 3D rendering, OCT fundus images and Advanced Visualization™.
  • Future ready. Previously captured CIRRUS cubes can be analyzed using new analyses.

3D and Advanced Visualization

Draw insights from perspectives beyond the cross-sectional B-scan. CIRRUS data cubes can be processed and mined with sophisticated 3D and en face visualization tools. Isolate layers of the retina to view en face. Fly through from different angles. The answers are in the cube and CIRRUS provides the tools to find them.

Anterior segment images

CIRRUS can image the angle or cornea with raster scans or a data cube. No add-on lens is required.

Diagnostic analysis you can trust

With Fovea Finder, AutoCenter™, normative data and the best macular segmentation overall, CIRRUS lets you transform information into insight to support your clinical decision-making.

Zeiss segmentation algorithms

Leveraging over a decade of experience with OCT, Carl Zeiss and its research collaborators strive for excellence in algorithms to segment layers for measurements. CIRRUS macular thickness, RNFL and optic disc measurements have been extensively validated, showing excellent repeatability and accurate segmentation. The optic nerve head algorithm is designed to precisely measure the neuro-retinal rim while accounting for tilted discs, disruptions to the RPE and other challenging pathology.

The new, groundbreaking Advanced RPE Analysis provides insight on dry AMD and pigment epithelial detachments using OCT technology alone. Ganglion Cell Analysis - adds new insights to complement RNFL and optic nerve head analysis.

Measurement centering with FoveaFinder and AutoCenter

On the macula, the unique FoveaFinder technology ensures the ETDRS and ganglion cell plus inner plexiform layer measurement frameworks are centered on the fovea. The AutoCenter™ function automatically centers the 3.4 mm diameter peripapillary RNFL calculation circle around the disc for precise placement and repeatable registration. The placement of the circle is not operator dependent. Accuracy, registration and reproducibility are assured.

Evaluate the patient against Normative Data

Normative databases are available for macular thickness, RNFL thickness, optic nerve head and ganglion cell plus inner plexiform layer thickness.

Spotting subtle pathology on the macula

In just seconds you can visually check the entire 6 mm x 6 mm region for any unusual or concerning structure. 3D layer maps are shown with the thickness analysis. “Fly through the cube” to view all 128 or 200 B-Scans in just seconds.

Spotting patterns of defects – Deviation Maps

CIRRUS enables you to see beyond the standard circle assessment for RNFL and across the macula for Ganglion Cell plus Inner Plexiform Layer thickness. Since CIRRUS normative data was collected for entire cubes, comparison can be made pixel by pixel across the 6mm x 6mm area. Wedge defects and other patterns of RNFL loss can be recognized and monitored.x

Central corneal thickness and angle assessment

CIRRUS can image the angle or cornea regions with raster scans or a data cube. No add-on lens is required. Calipers enable measurements including central cornea thickness.x

Change analysis you can trust

With precise, automatic visit-to-visit registration, you can both visualize and accurately measure change. New and improved GPA now includes optic nerve head parameters.

FastTrac Retinal Tracking to Track to Prior Scan position (CIRRUS HD-OCT 5000)
Place HD Raster scans in the same position as the prior visit. Then, visual comparison can be made, toggling back and forth between the current and prior B-Scans. CIRRUS data cubes also use FastTrac to scan the same location as previous exams.

Post-Acquisition Registration
CIRRUS data cubes are automatically registered to cubes from prior visits after the scan is acquired. Data from the current cube is aligned and rotated as necessary to allow pixel by pixel comparisons to the prior visit.

Precise Macular Change measurements and visualization
Macular Change Analysis provides measurement from two visits and provides a thickness change map . You can compare current and prior B-Scans side-by-side to the B-Scan in that position from the prior visit.

Guided Progression Analysis (GPA™) for Assessing RNFL and Optic Disc Change
GPA™ compares RNFL thickness and optic disc measurements over time and determines if statistically significant change has occurred.
Focal Progression Analysis – Up to 6 progression maps are compared to two baselines. Areas of statistically significant change are color-coded yellow when first noted and then red when the change is sustained over consecutive visits.
Trend Analysis with Rate of Change – RNFL thickness values are plotted over time. Trends are calculated and confidence intervals are shaded when rate of change is statistically significant.

Superb Practice & Workflow Efficiency

Capture high quality reproducible results with minimal training even on challenging patients. Keep patient exams moving quickly without getting bogged down. Connect to EMR and FORUM with expanded capabilities to share data among instruments and review stations.

FastTrac Retinal Tracking
CIRRUS models 5000 and 4000 can use FastTrac retinal tracking system to avoid motion during acquisition. FastTrac can be turned off when desired.

Just Seconds for Data Cubes or Raster Scans
Using Mouse-Driven Auto Alignment™, positioning the patient and the OCT scan is just a few clicks away. The process is streamlined further for the next visit with Auto Patient Recall™, as the motorized positioning can be reset to the same settings as last time. Acquisition time is extremely short. Live Precision Targeting™ allows operator to move scan box without moving fixation.

Up to the Challenge of Small Pupils and More
To sustain an efficient workflow, an OCT system must be able handle all type of patients including the challenging ones. CIRRUS OCT scans can routinely penetrate pupil sizes of 2 mm. Cirrus also performs optimally on moderate cataracts. Short acquisition time enables extremely quick re-scanning if required.

Efficient Use of Space
CIRRUS has a small footprint and the 90 degree patient to operator orientation enables you to position the product in tight spaces.
