Patient preparation

Prior to testing the, inform the patient of the test procedure, and familiarize the patient with the virtual
reality goggle and the handheld remote.
Be aware that the patient is in the dark throughout the examination and may suffer from disorientation. It
is therefore important that the patient understands clearly how to perform the tasks required.
Make sure that the exchangeable components (face cushion, head strap) are correctly mounted on the
virtual reality goggle and are fully functional. The head strap should be exchanged If the Velcro hook-and-
loop fasteners are worn or are prone to slippage.
