Every breakthrough product begins with a simple idea, and for Virtual Field, that idea was to make visual field testing smarter, faster, and more accessible for both clinicians and patients. What began as an experimental prototype built on the promise of VR-based perimetry has evolved into a clinically validated diagnostic platform used around the world.
From its earliest iterations to today’s AI-powered VR systems, Virtual Field reflects a balanced progression of innovation, accuracy, and patient-centered design. Supported by the engineering expertise of Micro Medical Devices, this technology has grown into a cornerstone of modern ophthalmic diagnostics.
1. The Vision Behind Virtual Field
Traditional perimetry is effective, but its limitations are well known. Large static bowl perimeters are expensive, stationary, and uncomfortable for many patients, especially children, seniors, and individuals with mobility challenges.
A team of engineers and clinicians set out to solve these issues by creating a portable VR-based perimetry system capable of delivering clinic-grade precision anywhere, from busy surgical centers to remote outreach locations.
The goal was simple: bring the accuracy of gold-standard perimetry into a lightweight headset.
This idea became the foundation of the Virtual Field project, combining VR innovation with ophthalmic science.
2. From Prototype to Proof of Concept
The earliest Virtual Field prototype used a VR headset equipped with precise gaze-tracking sensors. Development focused on replicating visual field stimuli in a controlled virtual environment that simulated the Humphrey field experience without bulky equipment.
Early Achievements
-
Fixation tracking performance comparable to standard bowl perimeters
-
Data mapping is consistent with Goldmann and Humphrey outputs
-
Responsive calibration that ensured stable sensitivity results
These successes proved that virtual visual field testing was not only feasible but also clinically reliable.
3. Engineering for Precision
Once feasibility was established, the next step was engineering a device that could deliver repeatable, dependable results across diverse patient groups. With support from the innovation-driven team at Micro Medical Devices, Virtual Field advanced rapidly into a clinically precise solution.

4. From Lab Testing to Clinical Trials
Before entering the market, Virtual Field underwent extensive multi-center clinical validation.
Clinical Evaluation Included
-
Comparing VR perimetry to the Humphrey Field Analyzer across more than 1,000 data points
-
Correlating with biometry, Pachymetry, and Keratometer readings
-
Testing on glaucoma, cataract, and neuro-ophthalmic patients
Results showed that Virtual Field matched or exceeded traditional accuracy benchmarks while significantly reducing test duration. A 15-minute bowl perimeter exam could now be completed in under 4 minutes with VR perimetry.
5. Clinical Integration Across Specialties
Following validation, Virtual Field entered routine use in a wide range of clinical environments.
