Dynamic Visual Acuity
Dynamic Visual Acuity (DVA) describes visual image stability where the vestibular ocular reflex (VOR) counters head motion by moving the eyes in the opposite direction to maintain a clear view of the world. The DVA-Test provides gain and retinal slip information by testing the Vision enhanced Vestibular Ocular Reflex (VVOR) in normal subjects such as pilots and athletes and in patients with vestibular or neurological disorders.
The DVAT computerized version will only present the character to the patient when their head is moving at a high velocity where only the VOR is functional and not pursuit. The test is also direction sensitive, so the right and left sides be tested separately. Vertical testing is also possible.
Fully customable test prococols with userfriendly interface.
No need to change any gyroscope position for horizontal and vertical test. Thank's to the built in 3D gyroscope.
Can be stand alone or as an option on the VNG system running with DiSoft II Pro Line.
