What To Know About The ZEISS CIRRUS 6000

The ZEISS CIRRUS 6000 is here!

ZEISS is releasing its newest premium performance OCT, the CIRRUS® 6000 that is designed to give eye care professionals (ECPs) the ability to capture images much faster and in greater detail than ever before.

Here is an overview of the major highlights and features of the ZEISS CIRRUS 6000, including some example images that will really show you what this product is capable of.

Speed of the ZEISS CIRRUS 6000

The CIRRUS 6000 features new hardware that is built upon speed. Faster scans mean better image quality, and the images that the CIRRUS 6000 can produce as a result of this performance upgrade are extremely impressive.

How fast is the CIRRUS 6000?

Really fast. 100,000 scans per second fast.

The CIRRUS 6000 has a scan speed of 100kHz. The older models many of us are accustomed to using in our practices, have scan speeds of 27 kHz (OCT) and 68 kHz (OCTA)

So what do these numbers actually mean?

The CIRRUS 6000 can capture:

  • OCT scans 270% faster than prior CIRRUS generations
  • OCTA scans 43% faster than the CIRRUS 5000 AngioPlex
  • OCT cube scans in as little as 0.4 seconds

Why is this major upgrade in speed so important?

Faster scans translate into two additional things that ECPs will really appreciate:

  1. Better image quality due to lesser chance for motion artifacts.
  2. The ability to capture more detail in the same amount of time as previous generation OCTs

We have all had those patients limited in their ability to be cooperative due to age, or other factors. How many times have your scans resulted in poor quality due to motion, loss of fixation, or blinking? Unreliable scans do not help in the decision-making process when it comes to diagnosis and management. A great image can sometimes make or break the ability to make a diagnosis with confidence.

At 100,000 scans per second, your ability to capture images quickly and in greater detail can make a massive difference for these difficult cases where other model OCTs are limited in the images they can produce.

Everything we do as ECPs is built around speed. It is no secret that there is an increasing amount of pressure on doctors to maintain the highest quality of care but to deliver it as quickly as possible. Having tools that can keep up with the demands of a busy practice is critical to deliver that efficiency.

Image Quality of the ZEISS CIRRUS 6000

With greater speed comes even better image quality. At 100,000 scans per second, degradation in image quality from motion artifact is greatly mitigated.

It is hard to imagine an improvement in image quality when current technology has allowed us to capture images in incredible detail, but the ZEISS CIRRUS 6000 has taken that ability to the next level.

Here are some images captured by CIRRUS 6000 that I think almost every ECP is going to be really excited about.

What about OCTA?

The ZEISS CIRRUS 6000 OCTA scans are 43% faster than the CIRRUS 5000 AngioPlex. At 100,000 scans per second, the CIRRUS 6000 facilitates the ability to capture High Definition AngioPlex scans also in greater detail than before.

How will this help in practice?

With improved image quality comes the ability to visualize the retinal layers and vasculature in greater detail without the presence of artifact or interference. This enhanced detail can be extremely beneficial for clinicians when it comes to improving confidence in managing and understanding the status and progression of disease states, while assisting in making more confident referrals.

Expanded Field of View of the ZEISS CIRRUS 6000

The ZEISS CIRRUS 6000 also delivers an expanded field of view to allow for deeper, more comprehensive imaging including:

  • Up to 12×12 mm wide OCT and OCTA scans in a single shot which means you can obtain a wide-field view of the retinal vasculature out to the arcades in one single scan.
  • Image up to 2.9 mm scan depth to better handle the retinal curvature and myopic eyes that can otherwise be challenging to image.

How can this be beneficial in practice?

The ability to capture widefield visualization of the retinal vasculature can greatly assist the clinician in appreciating diseases like early diabetic retinopathy, sickle cell, chorioretinitis, and vein occlusions.

ZEISS CIRRUS 6000 Analytics and Compatibility of Data

A major benefit of the CIRRUS 6000 is that it allows seamless transfer of raw patient data from any of the previous generations of the CIRRUS. This ensures your ability to analyze old, new, and future patient data is preserved, despite new technological advancements.

One of the most frustrating and perhaps biggest fears when it comes to upgrading or changing instrumentation whether hardware or software, is the loss of or inability to access patient data in its most raw form.

Anyone that has upgraded diagnostic instrumentation in the past or assumed the care of a glaucoma patient for example, from another practice or provider, has probably dealt with that dreaded folder that accompanies them containing all of their paper printouts or PDF results of visual fields, OCT, or other diagnostic testing. It is a nightmare to deal with in regard to processing data and information internally, but more importantly, you lose your ability to effectively assess change in the patient’s status from those critical early data points which as we know is imperative in progressive disease states like glaucoma or macular degeneration.

A PDF printout is certainly better than nothing, but it only presents the data and gives you an understanding of that patient’s condition or disease state up to that moment in time or compared across a specific set of points in time.

As artificial intelligence (A I) continues to advance and become a larger part of healthcare and subsequently eye care, retaining this raw patient data will be the key to utilize AI to its full potential, which is why this backwards compatibility is so beneficial not only for the present but the future.
