3.4.3 Side mounted camera goggles
The VisualEyes™ side mounted goggles (Figure 3.4-3) allow the recording of eye movements during various
test conditions, both with and without visual stimulation. The VisualEyes™ side mounted goggles use either
FireWire® or USB cameras to record eye images. The cameras use infrared light (IR), which is not visible to the
naked eye.
Figure 3.4-3 The FireWire® or USB cameras are fixed on the sides of the goggles (Left). Side mounted camera
goggles with replaceable foam pads (Right).
The side mounted goggles come with replaceable foam pads that are meant for single use as reuse
of foam pads can cause cross contamination. This should be changed after every single use by
pulling the used foam pad off of the hook and loop pads on the inside of the mask and then aligning a
new foam pad on top of the hook and loop.
The front cover plate of the side mounted goggle is magnetically fixed and can easily be removed for visual
stimulation tests (i.e. oculomotor). The mask has an adjustable Velcro head strap that comfortably secures the
goggles to the patient. The side mounted camera goggles can be configured with one camera and cover for
monocular systems. In this configuration, the user would physically move the camera to the side of the goggles
to record the desired eye, and the cover would be placed on the other side to block out light in vision-denied
tests.
3.4.4 Top mounted camera goggles
The binocular video goggles (Figure 3.4-4) block out ambient light with the easy-to-place cover over the portal
for vision-denied testing. Side-lights on the goggles are programmed to flash to remind the operator which ear to
irrigate during the caloric test and are also used to provide illumination when placing the cover on the goggles.
There is a switch on the left side of the goggles to start and stop tests. The binocular video goggles have an
adjustable Velcro head strap that secures the goggles while still providing patient comfort.
