Indications

Hypertrophy of the orbicularis oculi muscle can cause a fullness of the lower eyelid when smiling or squinting but is not noticeable at rest.

Anatomic Considerations

The orbicularis oculi muscle surrounds the eye and is divided into three parts: orbital, preseptal, and pretarsal. Hypertrophy of the pretarsal portion of the muscle can result in a fullness of the lower eyelid when the patient smiles.

Injection Technique

Botulinum toxin (1 to 2 BU) is injected at the midpupillary line approximately 3 mm below the lash line. A single injection is placed per eyelid. The injection is immediately subcutaneous.
