and without visual stimulation. The VisualEyes™ side mount goggles hold FireWire® or USB cameras that
are used to record the eye images. The cameras use infrared light (IR), which is not visible to the naked eye.
The IR illumination enables sessions to be performed in complete darkness.
The FireWire® or USB cameras are fixed on the sides of the goggles (Figure 3.6.3).
Figure 3.6.3 Side mount camera goggles
The goggles come with replaceable foam cushions (Figure 3.6.4) that are removed between patients by
pulling the used foam cushion off of the hook and loop pads on the inside of the mask and then aligning a
new foam cushion on top of the Velcro.

The front cover plate of the side mount 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. Side mount 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.

3.6.4 Top mount camera goggles
The binocular video goggles (Figure 3.6.5) 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. On the left side of the goggles is a switch to start and stop tests. The binocular video
goggles have an adjustable Velcro head-strap that secures the goggles while still providing patient comfort.

3.6.5 Front mount camera goggles
The front mount camera goggles use a single USB camera pressed into the camera portal on the front of the
goggles mask. The camera can be placed into either camera portal to record the desired eye. The cable is
secured in the cable clip above the portal. Each portal has a swivel cover plate to provide vision-denied
testing. The goggles have an adjustable head-strap that secures the goggles while still providing patient
comfort. The front mount camera goggles are typically used for smaller and younger patients.

3.6.6 Rotary chair (optional)
The reclining rotary chair provides sinusoidal harmonic acceleration (SHA) test and step test capability to the
VisualEyes™ system. The reclining rotary chair can also be used as the exam table for positional and
caloric testing. The backrest can be reclined to 30 degrees from horizontal for caloric irrigations. Positional
tests can be performed with the backrest reclined to 0 degrees horizontal. For Dix-Hallpike tests, the
headrest can be removed on the System 2000 and Orion chairs to allow the clinician to bring the head below
the frame. A head strap located on the back of the System 2000 and Orion chairs’ headrest secure the
patient’s head to the head rest during rotation tests.

3.6.7 The foot pedal (optional)
The foot pedal (Figure 3.6.8) allows you to begin the measurement testing by pressing the foot switch so
you have both hands free to look after the patient (e.g. Dix-Hallpike) or to operate other devices (e.g., caloric
irrigators). Connection with the PC is via a USB port.
