Traumatic blepharoptosis

The objective of this chapter is to review the various etiologies and management of traumatic blepharoptosis. Iatrogenic causes constitute the most common category of factors in traumatic ptosis. This includes ptosis postintraocular surgery and posteyelid and adnexal procedures. Contact lens wear, various systemic interventions, and birth trauma are other iatrogenic causes reported in the literature in association with upper lid blepharoptosis. Lacerations and blunt traumatic injuries to the upper eyelid are frequently associated with various degrees of blepharoptosis. Neurogenic ptosis secondary to head trauma can occur secondary to third nerve injury, superior orbital fissure syndrome, or traumatic facial nerve palsy. The prognosis and management of traumatic ptosis depends on the underlying mechanism of injury.
