 Now, here's a fairly wild example. This patient had trauma as a youth and was left with both a third and a sixth nerve palsy. Now, watch these eye movements. Here's a patient with synchonetic responses between the third and the sixth nerve. Forward gaze, the eye is deviated out. Now, look at that. When the patient looks to the right, the left eye responds with ABduction, implying that the third nerve has been miswired to the sixth nerve. And there's further evidence of this by watching the patient look vertically. This mainly indicates synchonesis of the third nerve. So this is aberrant regeneration of both the third and the sixth nerve. In this case, there was a history of trauma. Here again, you can see that aberrancy with synchonesis between the third and the sixth. The patient looks to the right, the left eye, ABducks. What we're doing here is simply demonstrating that the deductions are full and normal in the right uninvolved eye.
