Summary
Traumatic eye injuries involving multiple extraocular muscles are rare. Prompt surgical repair of transected or avulsed muscles, like the inferior rectus and medial rectus, is crucial for optimal functional recovery.
Area of Science:
- Ophthalmology
- Trauma Surgery
- Reconstructive Surgery
Background:
- Extraocular muscle avulsion or transection from trauma is uncommon.
- Surgical repair strategies for such injuries are infrequently reported.
Observation:
- A case of penetrating metal hook injury is presented.
- The injury resulted in partial avulsion of the medial rectus muscle.
- Complete transection of the inferior rectus and inferior oblique muscles occurred.
Findings:
- Successful identification and primary surgical repair of all injured muscles were performed.
- The patient achieved an excellent functional outcome post-repair.
Implications:
- This case underscores the necessity of thorough surgical exploration after penetrating eye trauma.
- Early and accurate repair of transected and avulsed extraocular muscles is vital for restoring ocular motility and function.

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...

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...
