The Easy, Accurate and Low-Cost way to measure subjective visual vertical in your patients

If you are practising neurology or vestibular rehabilitation you should be testing subjective visual vertical in your patients. It has been shown to be a sensitive and reliable test for brainstem lesions and is one of the few tests available for otolithic function.

However, up until now testing subjective visual vertical required costly and bulky equipment and totally dark rooms. The Visual Vertical application for iphone and ipad changes all that. With just your iphone, some bluetack and a bucket (yes really, a bucket!) you can take accurate readings in just a few minutes, for a tiny fraction of the normal cost.

The Lite version of the app includes the ability to do single, one off readings of each eye. For the ability to do sequenced averaged testing of the eyes choose the full version.
