Neurogenic Ptosis: Evaluation And Management

In this chapter, we discuss neurogenic ptosis using an anatomical approach. Neurogenic forms of ptosis are important to recognize; in fact, in some cases ptosis is a key sign leading to the diagnosis of a life-threatening condition. The neuroanatomical circuitry is well characterized; however, following damage, interesting and complex reorganization can take place. Accurate diagnosis and appropriate intervention depends on a solid understanding of the underlying pathophysiology of these aberrant regeneration syndromes. We will cover the most common of these entities here, with representative examples throughout.
