VisualEyes™ EyeSeeCam is intended for patients from 5 years of age and above. The patient must be
physically sound as the procedures include some physical stimulation/movement. The patient must be able
the see the target without the use of spectacles.
Contraindications
VNG and vHIT testing may be contraindicated in patients who exhibit the following: blindness, broken nose
or other face/head trauma, recent eye surgery and lazy eye.
ENG testing is not recommended in patients with a cardiac pacemaker or any other electric/magnetic
implanted devices, as the electrical equipment may interfere with the device’s function.
Patients with strong defective vision, ptosis or abnormal blinks should be tested with caution as these
conditions can lead to artifacts. Patients with severe back/neck problems may be excluded for positional and
vHIT tests. Any other relevant clinical history or medication of an individual patient should be considered
before starting a test. A medical specialist should be consulted for further information or guidance on clinical
conditions that require additional attention before starting the test.
