Clinical Trial Validates RadiusXR’s Advanced Diagnostic Accuracy

Exceptionally high correlation of 0.94

The NOVA Clinical Trial validates RadiusXR’s advanced diagnostic accuracy in Visual Field Testing for Virtual Reality Perimetry. The trial revealed remarkable findings, including statistical non-inferiority to current clinical standards for sensitivities at individual test locations, with high concordance in glaucoma staging using Medicare definitions, and an exceptionally high correlation of 0.94 mean deviation.

Out of 100 participants, half were previously diagnosed with moderate or severe glaucoma, and the other half were mild or suspect.

PULSE: Perimeter User Learning Satisfaction Evaluation

Background

Automated visual field testing devices are a key tool in detection, diagnosis, monitoring, and management of various ocular and neurological conditions. Traditional devices have been used in clinics for decades with advances in analysis and testing strategy but little change in the patient experience. Headset automated visual field technology presents an opportunity to change the patient experience. However, VR perimetry presents new questions and challenges.

Results Key Points

  • RadiusXR’s VR perimetry patient experiences were found to be non-inferior to legacy bowl perimeters
  • Data shows broad patient acceptance of the new technology; preferred over legacy perimeters
  • Patients had minimal reports of negative experiences during testing
