SORRY! I should have been more clear. I was referring to the Vimeo video from the example of the case based exam #3, question number 2. It is the patient’s right eye and at first it looks to me as if the fast phase is going in medially toward the left. After watching it a few more times, I can slightly see how the fast phase is going toward the right. Hopefully with more practice it will clear up for me.
Is there any pattern with the direction of the dix-hallpike being performed and the symptomatic side being the involved ear? For example, since the is a dix-hallpike with right head rotation and there is positive nystagmus, can it be assumed that the involved canal is on the right side? Or would a left dix-hallpike also produce this result? THANK YOU!!
For interpreting nystagmus on case 3, It’s very difficult for me to see that the upbeat is toward the right… I see the torsion and quick beat going toward the left side, since I am looking at the right eye. Am I looking at this incorrectly? Should I be thinking of it as clockwise vs counter-clockwise?
