Choosing the Best Technology

Selecting a platform backed by science and validated data

The Problem

The responsibilities of an ophthalmological clinician are many, and diverse. He or she of course must be a top-notch medical professional, abreast of the latest scientific advances in the field. But for a practice, and most importantly its patients, to thrive, a clinician must also be savvy about managing the business.

The decision to invest in any clinical technology merits careful evaluation. There’s a lot at stake. George Tanaka, MD, of San Francisco’s Tanaka Vision, lays out the problem: “Ophthalmologists have several options when they’re looking at virtual reality visual field testing.” What makes one better than others?
“
One of the options that was important to me — how would it compare to the traditional Humphrey visual field?” says Howard Barnebey, MD, Specialty Eyecare Centre in Bellevue WA.

Nathan Radcliffe, MD, of the New York Eye Surgery Center, explored the options by getting very hands on: “I heard about the Radius system from a number of my friends who were really pleased with the results and with the practice efficiency. I then began looking into it and was honored to be invited to be one of the graders in the NOVA study.”
“
This is not simply a flashing light on a black background. This is driven by science on triggering the magno part of the cellular pathways with specific stimulus size and specific luminance. That really convinced me that this was real technology, packed into the smallest headset available for virtual reality visual field.”

The RadiusXR Solution

What was Dr. Radcliffe’s takeaway from the NOVA study of the RadiusXR system? “The correlation between traditional and virtual perimeter was 0.94, which is the highest that I’ve ever seen,” Radcliffe says.

Clinicians who have had first-hand experience with the RadiusXR are similarly won over by the device’s high performance.

“
What I really liked about RadiusXR was that the fact that this was a headset that was designed from the ground up to do visual field testing,” Dr. Tanaka explains.

“
It uses a lot of the same parameters that we see with traditional Humphrey field testing,” says Robert Noecker, MD, of Ophthalmic Consultants of Connecticut, “and it makes the test very translatable.”

George Reiss, MD, of Eye Physicians and Surgeons of Arizona in Phoenix agrees: “Our data shows that the RadiusXR type field does extremely well and provides us excellent data that we can use for even follow-up exams.”

Brian Shafer, MD, Shafer Vision Institute, Philadelphia PA, explicates how the technology works: “This is not simply a flashing light on a black background. This is driven by science on triggering the magno part of the cellular pathways with specific stimulus size and specific luminance. That really convinced me that this was real technology, packed into the smallest headset available for virtual reality visual field.”


RadiusXR’s unique combination of low profile and high performance make it a smart investment for fiscally responsible clinicians seeking great solutions for patient care.
