The Effect of Ptosis Surgery on Brow Position and the Utility of Preoperative Phenylephrine Testing

Abstract

Approximately 15% of the population studied tends to have a significant change in brow position with ptosis surgery. Patients who do not demonstrate a reduction in brow height of at least 3.5 mm after phenylephrine instillation preoperatively are unlikely to have clinically relevant brow height reduction after surgery.
