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.

The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
Muscles for Facial Expressions01:14

Muscles for Facial Expressions

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
Muscles of the Eye01:20

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
Muscles that Move the Head01:19

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Anatomy of the Eyeball01:20

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
