Virtual Reality: The Future Of Visual Field Testing

One of the most important tests available to assess human vision is the visual field test, or perimetry. While imaging of the fundus and standard tests such as Snellen charts can assess factors such as acuity, and identify damaged parts of the retina, only the visual field test can measure the subjective field of view of perception from the patient side. We introduce a Virtual Reality (VR)-based perimetry test. A systematic test for measuring the visual field function conducted in VR. The VR-based test is precise enough to supersede the standard perimetry test carried out on either a Goldmann or Octopus test machine. Using VR allows for a more comfortable experience and opens up for further development that can potentially be used to map out other deficiencies of the visual field function. It also provides the ability to gamify the test allowing it to be carried out on children. Here we present some of the considerations and implementation details which ensure that our software has the necessary capabilities of producing correct measurements and valid results.
