Walsh & Hoyt: Generalized Disturbances of Autonomic Function

Dysautonomi is a term used to describe any congenital or acquired anomaly in the autonomic nervous system that adversely affects health. This can result in a variety of clinical symptoms, ranging from transient episodes of hypotension to tonic pupil syndrome to progressive neurodegenerative disease. It is not the intention of this chapter to provide a detailed description on the numerous dysautonomic syndromes; however, a few comments will be made on the disorders in which ocular findings are early or prominent signs.
