What This Comparison Shows

While many newer visual field systems emphasize convenience, speed, or broad test menus, Inspire stands apart by prioritizing clinical alignment with established perimetry standards.

Key Differentiators Include

Purpose-built medical hardware rather than repurposed consumer VR

HFA-matched background luminance

Support for standard threshold strategies, including 30-2

Significantly lighter headset for improved patient tolerance

Lower visual field test cost compared to many headset-based competitors

Designed to complement, not replace, established clinical workflows

Inspire bridges the gap between legacy bowl perimeters and newer VR platforms by combining clinical rigor with 
real-world usability.

Clinically Validated and
Patient-Preferred

While many newer visual field systems emphasize convenience, speed, or broad test menus, Inspire stands apart by prioritizing clinical alignment with established perimetry standards.

Proven Clinical Accuracy

Demonstrated 0.94 correlation with traditional automated perimetry (NOVA study)

Comparable Patient Experience

Patient experience found to be non-inferior to legacy 
bowl perimeters

Patients Prefer Inspire

79.85% of patients preferred Inspire over traditional visual 
field devices

Minimal Reported Discomfort

Minimal negative symptoms reported during testing

These findings support Inspire as a reliable visual digital healthcare solution suitable for routine clinical use.
