The Olleyes VisuALL Analyzer (vFA) is a virtual reality visual
function platform designed to monitor the retinal sensitivity in patients with
eye diseases. This mobile device performs Standard Automated Perimetry and
other psychophysical tests, including assessment of visual acuity, color vision,
contrast sensitivity, pupillometry, and extraocular motility.
The VisuALL is a portable automated
perimeter that uses a virtual interface that has the potential to provide an
immersive testing experience for patients. The VisuALL has two displays (one
for each eye), allowing it to test both eyes simultaneously but separately with
a similar test duration to other perimeters.
The VisuALL Virtual Reality Software suite
works with the seamless synergy of three elements: the WebApp, the Cloud, and
Olleyes Approved VR Headset.
Annie, a Virtual Assistant, is designed to
boost efficiency, monitor patients, explain the testing process to patients,
and organize the test data for easy reading.
The headset runs the VisuALL Patient
Testing Application (PTA), which was written in Unity (a cross-platform gaming
engine). By leveraging this engine, VisuALL can create a fully immersive and
self-contained environment in order to perform self-directed, interactive
training tutorials for the patient and then proceed to the VF test.
Another key component of the VisuALL PTA is
the proprietary thresholding algorithms, which implement complex decision trees
to determine most efficiently what the patient's threshold for light detection
is at each location.
The VisuALL uses Goldmann size III test
stimuli in each VF protocol and tests both eyes simultaneously.
The vFA has both strong short-term and
long-term test-retest reliability in addition to high correlation with HFA in a
standard clinical setting.
After testing is complete, the software
generates a report that includes the patient's name, date of birth, gender,
test ID, examination date, test time, and test strategy. It also lists the
fixation losses, false positives, and false negatives. Below is a plot of the
threshold values for each of the 50 points tested, and a grayscale
representation of the threshold values.
