Carl Zeiss Cirrus HD-OCT 5000 Smart Advanced Topography HD

Analyzing a single pathology from multiple views provides comprehensive insight and analysis of the clinical situation. 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 placed in the vicinity of 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.

FastTrac™ reduces eye motion artifacts without sacrificing patient throughput with a proprietary scan acquisition strategy, high speed 20 Hz LSO camera, and single-pass alignment scanning
With FastTrac, scan at the highest resolution at the same location at each visit.

On the macula, the unique FoveaFinder technology ensures the ETDRS and ganglion cell plus inner plexiform layer measurement frameworks are centered on the fovea.

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.

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.
