Which is best for my application, VNG Monocular (one camera, 2 channel) or VNG Binocular (two cameras, 4 channel)?
The primary advantage to binocular recording rather than monocular is that with monocular you can often overlook disconjugate eye movements (i.e., when the eyes are not moving synchronously together).
This would be most common with paralyses of one or more of the extraocular eye muscles or with lesions affecting the medial longitudinal fasiculus which is the major pathway that pairs the eyes together for versional horizontal deviations. Often times you may also have one eye that captures or records poorer than the other such as with individuals who have had prior eye surgeries in which case having dual recording is also more beneficial.
