Isolated traumatic neurogenic ptosis with delayed recovery

Area of Science:

• Ophthalmology
• Neuroscience
• Traumatology

Background:

• Isolated neurogenic ptosis can result from injury to the levator palpebrae superioris nerve.
• Tractional injuries to the eyelid are a potential cause of such nerve damage.

Observation:

• A retrospective case review identified three patients with presumed neurapraxic injury to the levator palpebrae superioris nerve.
• Two patients had a history of upper eyelid traction; one experienced mild, transient superior rectus underaction.

Findings:

• Maximal recovery from this nerve injury occurred within a period of up to six months.
• The findings suggest that traumatic neurapraxic injury to the levator palpebrae superioris nerve is associated with specific upper eyelid injuries involving significant forward traction.

Implications:

• This condition, while potentially recovering within weeks, may require up to six months for full recovery.
• Understanding the mechanism of tractional injury is crucial for diagnosing and managing isolated neurogenic ptosis.
• Ophthalmologists should consider neurapraxic injury in cases of ptosis following eyelid trauma.
