The Importance of Peripheral Sight
20/20 vision does not always mean healthy eyes. In fact, many people with glaucoma, retinal detachment, stroke or other vision-threatening conditions can have significant visual impairment despite 20/20 reading vision. Hidden blind spots can go unnoticed in the corner of our sight for quite some time unless we pay close attention to what’s happening in the peripheral part of our visual field – a part that accounts for more than 80% of our retinal and optic nerve function.

What is Peristat
Peristat is a 5-minute online test of your visual field function to check for hidden blind spots. Similar to a test eye doctors routinely use in their offices called perimetry, Peristat is an online home test of your peripheral visual function. Delivered via the KeepYourSight telemedicine platform, in clinical studies Peristat has detected moderate to severe visual field defects with high accuracy1,2

- Perimetry testing of up to 24 degrees of visual field
- Contrast sensitivity mapping of the visual field
- Multi-level threshold retinal contrast stimulation and interrogation
