Optical coherence tomography [OCT] provides tissue morphology imagery at much higher resolution than other imaging modalities such as MRI or ultrasound, and the machines are comparatively cheaper.  It is an easy technique to perform; is non-ionizing, and therefore safe.  These benefits are driving a rapid transformation of OCT, from its principal application as a research tool, into an extension of the  neurological examination  in routine office practice.  Originally used in assessing the severity of tissue damage and prognosis of multiple sclerosis and various neuro-ophthalmic conditions, OCT is increasingly used in other neurological disorders such as Parkinson s disease, ALS, and Alzheimer s disease.  This book is the first comprehensive review of the use of OCT in neurological diseases.  The coverage includes a description of the technique and its utilization in a variety of neurologic conditions.
