I recently made a bold claim: You cannot holistically assess vestibular dysfunction without understanding ocular motility. Today, we start building that foundation. Part 1 of our 5-part series begins where all eye movement understanding must begin: How do the eyes actually move together? We’re building toward understanding why posterior canal BPPV creates “upward” nystagmus when […]

Click here to get the ‘Part 5: BPPV Nomenclature is Canal-Based — NOT Muscle Based’ handout The posterior canal connects to the ipsilateral Superior Oblique (SO) and contralateral Inferior Rectus (IR) — muscles that pull the eye DOWN. So why does posterior canal BPPV produce UPbeating nystagmus? If you’ve ever paused mid-explanation, trying to reconcile muscle […]

Click here to get the ‘Neural Asymmetry & The Recovery Paradox’ handout We’ve explored the VOR—how semicircular canals drive compensatory eye movements through elegant push-pull dynamics. But here’s what the anatomy lesson doesn’t tell you: When peripheral vestibular function is lost, how much of VOR recovery actually comes from the periphery healing? In patients with […]

Click here to get the ‘Semicircular Canal Influence – The VOR Connection’ handout In Parts 1 and 2, we built the foundation: conjugate gaze and how individual muscle actions combine into synergistic patterns. Now the payoff: why the vestibular system cares about all of this. The VOR isn’t random. It exploits the exact same muscle […]

Click here to get the ‘From Primary Cranial Nerve Actions to Functional Synergistic Patterns’ handout We learn the extraocular muscles one at a time. Clean. Organized. Easy to memorize. But here’s the reality: our patients don’t functionally move one muscle at a time. When your patient looks up, each eye fires both its Superior Rectus […]

There’s a reason. I’m in the middle of a series on extraocular muscles, cranial nerves, and VOR connections. But I wanted to pause and share […]

Register for free below and join us for an interactive discussion on the following 5 Nystagmus Video Cases! We will watch each nystagmus case video and answer questions specific to each case.   Nystagmus Video: Case 1A 27-yo-male with the acute onset of vertigo and angina post-COVID. He was seen in the ED, having a normal cardiac work-up […]

As frequently stated by neuro-optometrist and 360 Neuro Health faculty member, Dr. DeAnn Fitzgerald: It’s a brain thang! Our nervous system controls everything we do. When it works well, you work well…your patients/clients work well. When there is dysfunction in the nervous system, however, there is typically dysfunction in the ability to carry out daily activities […]
