Introducing the Third Eye Panoramic

The Third Eye Panoramic device allows endoscopists to see more of the colon during a colonoscopy.

The new device clips onto the tip of a standard colonoscope to provide two additional video cameras. Combining the three images results in a 330° “panoramic” view.

This ultra-wide-angle view reveals areas of the colon’s lining that are hidden from the view of the colonoscope.

Expand the View of Standard Colonoscopes

In an effort to improve the quality of colonoscopy, researchers are measuring endoscopists’ Adenoma Detection Rates – or “ADR” – defined as the percentage of patients in whom they find at least one adenoma.

Guidelines suggest that endoscopists should find at least one adenoma in at least 20% of their female patients and 30% of male patients.

In a recent study of the Third Eye Panoramic device, endoscopists detected at least one adenoma in 44% of the patients they examined using the device along with a standard colonoscope.7

Colonoscopy is the gold standard for detecting and preventing colon cancer, and the three major colonoscope manufacturers have developed instruments that provide extremely high-quality images.

However, like most procedures, colonoscopy is not perfect.

Surprisingly large numbers of polyps can be missed during colonoscopy due to a limitation of the technology:

Standard colonoscopes have only a single camera that aims directly out from its tip. If the colon were a straight tube, that camera could see everything inside. However, the colon has many folds in its inner lining, and it contains many sharp turns, or flexures. The areas behind those folds and flexures are often hidden from the colonoscope’s view.

Even highly-experienced endoscopists – using the latest colonoscopes and meticulous technique – miss some lesions that are located behind folds.

The Third Eye Panoramic Device

The Need:

  • Standard colonoscopy misses at least 24% of adenomas1-3 and 12% of large adenomas (≥1 cm)4-6
  • 2/3 of missed adenomas are hidden behind folds4

The Solution:

  • The Third Eye Panoramic clips on to the end of any standard colonoscope to provide two side-viewing video cameras that work along with the colonoscope’s camera.
  • The resulting 330° panoramic view reveals more of the colon’s lining, including the areas behind folds.

Most colon cancer is preventable with early detection.
