where all eye movement understanding must begin

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?

• Part 1: Primary EOM Actions & Conjugate Gaze – The Foundation

• Part 2: From Primary Cranial Nerve Actions to Functional Patterns

• Part 3: Semicircular Canal Influence on VOR Function

• Part 4: Neural Asymmetry and The Recovery Paradox

• Part 5: BPPV Nomenclature is Canal-Based — NOT Muscle Based

We’re building toward understanding why posterior canal BPPV creates “upward” nystagmus when the muscles pull DOWN (Part 5). Each part in this series builds on the last.
