Eye bobbing associated with jaw movement
Insights
This study describes a rare eye movement disorder, termed "eye bobbing," observed in two patients. Eye bobbing involves abnormal globe movements linked to jaw actions, potentially sharing an etiology with Marcus Gunn jaw-winking.
Area of Science:
- Ophthalmology
- Neurology
- Pediatric Medicine
Background:
- Marcus Gunn jaw-winking is a congenital condition causing eyelid elevation during jaw movement.
- A previously unreported disorder involving abnormal globe movements synchronous with jaw actions was observed in two pediatric patients.
Purpose of the Study:
- To describe and analyze a novel presentation of abnormal ocular motility related to jaw movements.
- To explore the potential shared etiology between this new disorder and Marcus Gunn jaw-winking.
Main Methods:
- Case study of two pediatric patients with congenital blepharoptosis and abnormal eye movements.
- Clinical observation of ocular motility during jaw movements (nursing and chewing).
- Review of embryologic development and innervation of related ocular muscles.
Main Results:
- Patient 1: Infant with blepharoptosis exhibited globe movements synchronous with nursing.
- Patient 2: Child with blepharoptosis and double elevator palsy showed globe and eyelid movements synchronous with chewing.
- Abnormal globe movements persisted after surgical intervention for blepharoptosis.
Conclusions:
- The observed
- eye bobbing
- is likely due to aberrant innervation of the superior rectus muscle during jaw movements.
- This phenomenon may share a similar pathophysiological basis with Marcus Gunn jaw-winking, supported by shared embryologic origins and innervation patterns of the levator and superior rectus muscles.
Abstract:
Two patients were treated for a previously unreported disorder believed to be related to Marcus Gunn jaw-winking. The first, a 9-month-old infant with left congenital blepharoptosis without jaw-winking and with normal ocular motility had an up and down movement of the left globe synchronous with nursing movements of the jaw. The second was a 5-year-old girl with left blepharoptosis, jaw-winking, and left double elevator palsy who had up and down movements of both the left upper lid and the left globe synchronous with chewing. The left globe movements were most prominent in the field of vertical action of the superior rectus muscle and persisted after levator excision and fascia lata sling procedures. The possible etiology of the Marcus Gunn jaw-winking phenomenon is discussed and related to our cases of eye bobbing. The eye bobbing probably is caused by abnormal innervation to the superior rectus muscle produced by jaw movements in a manner analogous to the abnormal stimulation of the levator muscle in jaw-winking. The similar embryologic development and innervation of the levator and superior rectus muscles add credence to this theory.
