Isolated Traumatic Neurogenic Ptosis With Delayed Recovery

Abstract

PURPOSE: To describe the entity of isolated neurogenic ptosis due to presumed tractional injury to the nerve of innervation of the levator palpebrae superioris, with recovery occurring over a period up to 6 months. METHODS: Retrospective case review. RESULTS: Three cases of presumed neurapraxic injury to the nerve of innervation to the levator palpebrae superioris are described. Two cases had a clear history of traction to the upper eyelid. There was no evidence of damage to other extraocular muscles or their nerves of innervation in 2 cases and mild transient superior rectus underaction in 1. Maximal recovery occurred over a period of up to 6 months. CONCLUSIONS: Traumatic neurapraxic injur..
