Isolated unilateral neurogenic blepharoptosis secondary to eyelid trauma.

PURPOSE: To describe eyelid trauma as a cause of isolated neurogenic blepharoptosis.

DESIGN

Observational case series.

METHODS

Three previously healthy patients (two male and one female; aged 29 to 39 years) were evaluated for unilateral blepharoptosis following forceful anterior displacement of the upper eyelid. Two injuries occurred during domestic altercations and one while the patient was playing basketball.

RESULTS

All three patients had complete unilateral upper eyelid ptosis with no levator palpebrae superioris function, consistent with loss of innervation. Additional findings included minimal eyelid ecchymosis, eyelid edema, and subconjunctival hemorrhage in two cases. The remainder of the examinations was unremarkable with full ocular motility and no anisocoria. Without treatment, within 2 weeks, all three patients recovered completely with normal symmetric lid height and levator function.

CONCLUSIONS

Isolated neurogenic blepharoptosis may result from traumatic anterior upper eyelid displacement. Resolution is likely within 2 weeks.
