Tarsal Switch Levator Resection for the Treatment of Myopathic Blepharoptosis
Progressive myopathic ptosis is often associated with fair to poor levator function. These patients usually adopt a head-back/chin-up position with heavy recruitment of the frontalis muscle to see, resulting in chronic neck pain and visual fatigue. In addition, these patients often have a poor Bell’s phenomenon and the orbicularis muscle can be weak, resulting in poor eye protective mechanisms. Surgical procedures to correct blepharoptosis in patients with poor eye-protective mechanisms are associated with an increased incidence of postoperative lagophthalmos and corneal exposure.
