Precise visual fields made easy
Novel digital endpoints for ophthalmology that delight your patients.
Conventional tests for geographic atrophy and glaucoma require unrelenting vigilance for many minutes at a time, which cognitive scientists know is exhausting. Vivid Vision Perimetry (VVP) is designed along proven principles from cognitive psychology to be easier to take. All their lives, your patients have made eye movements toward things that attract their attention in peripheral vision. Join them, don't fight them: in VVP, our "fixation task" makes it natural to fixate before each stimulus.
Tired of telling your patients that they're "trigger happy" and need to re-take the test? VVP uses an advanced psychophysical approach so patients can guess as often as like without biasing test results.

Enhancing Endpoint Precision in GA Trials
The latest study of Vivid Vision Perimetry (VVP), led by Dr. Karl Csaky at Retina Foundation of the Southwest and supported by Regeneron, demonstrates that an at-home VR-based vision test not only matches the accuracy of in-clinic microperimetry but also provides even greater precision.
“Our results demonstrated that the VVP Swift test can generate reproducible results and is comparable with conventional SAP.”

It is typical for conventional SITA testing (assuming) two tests per year, with standard values of sensitivity = 0.8 and specificity = 0.95) to take 2 two years to differentiate two patients with rates of loss of 2 dB/year and 0 dB/year. With three at-home VVP-10 tests separated by 3 months VVP can differentiate the two patients in just 6 months, letting you know if they are progressing or if their vision is stable.
Track individual lesions
Use our Stimulus Placement Tool to track individual lesions with high spatial precision.
Customization via a Web-Based Interface
Using the participant’s retinal images (including FAF and OCT scans), we identified where the damage (lesion) was located on the retina and mapped out exactly where to place test stimuli. We also corrected for each participant’s natural eye position and any possible rotation of the eye (cyclotorsion).
Deployment to a VR Headset
Each customized test was then loaded into the VR headset running our Vivid Vision Perimetry (VVP) software. This allowed participants to do the test from the comfort of home.
Test Bundle: 10 Sessions Over 5 Days
After a quick in-clinic training session, participants took the headset home and completed 10 test sessions in just 5 days. On average, each session took under 20 minutes.
Comparisons with Microperimetry
Meanwhile, each participant also underwent traditional microperimetry (MAIA) in the clinic, so we could compare test-retest variability, mean sensitivity values, and fixation precision.
