Zeiss Cirrus 4000 HD-OCT

Despite the expense and investment, the Cirrus 4000 is and was the first spectral domain OCT with posterior and anterior imaging of this diagnostic capability and competence.

Overview

An estimated 39,000 diagnostic OCT scans are taken in America daily– a number that is only growing as the technology becomes more mainstream and affordable. At the forefront of this ophthalmic tomography, is no other than major manufacturer Carl Zeiss Meditec and their Spectral Domain Optical Coherence Topographers. Since its inception, the Cirrus is undoubtedly the market leader, and in our opinions, makes the best OCT offered anywhere. It starts with the fact that no external computer, monitor, or anything for that matter is necessary to operate it; everything is built-in and fit into a giant boat-like triangular thing. Except it’s not a boat thing, it’s a yacht carrying the greatest and latest Ophthalmic technology bundled into a large computer that still sits on your pretest table. Yes, it is big, but it’s extraordinary to look at; overly impressive, awe-inspiringly futuristic and robotic. But you don’t buy an OCT to look at it (it will make your Optometric practice seem more scientific and medically versed however) you make this investment for the imagery, and Cirrus delivers on all fronts. Cirrus gives you the ability to view pathologies from multiple vantage points—and with a range of at-a-glance visualization formats. From the basic LSO Fundus Imaging, to the Macular Thickness Map, to the HD 5 Line Raster display, to the 3D visualization…you’ll be able to assess your patient’s condition and determine the appropriate course of action better than ever before. And that’s before we’ve even discussed the data-packed Cirrus Cube. It is the literal trophy of owning a Cirrus and a tightly packed, detail-rich cube of data (captured in just seconds) that allows you to visualize and analyze your patient’s condition. The multi-layered cube is a product of 67 million total data points being produced multi-dimensionally in a 2.4 second scan– what a way to explore pathology. It’s possible by directing tightly spaced A and B-scans in 512×128 scan patterns which closely capture subtle defects or central fovea pathology. This data is then fed into Zeiss algorithms and compared with normative data for accurate segmentation and reproducible measurements. This makes capturing the 3-D cube only the beginning, granting you the ability to see beyond the scan and transform information into insight.
