Book excerpt: Thoroughly revised and updated for its Sixth Edition, this classic work is the most comprehensive reference on diagnosis and treatment of neuro-ophthalmologic diseases. This edition has two new editors--Valerie Biousse, MD and John B. Kerrison, MD--and has been streamlined from five volumes into three tightly edited volumes with a sharper focus on patient management. Coverage includes major updates on genetics of diseases, new diagnostic techniques, and the newest treatment options. This second volume covers tumors, the phacomatoses, and vascular disease. Volume 1 covers the visual sensory system, the autonomic nervous system, the ocular motor system, the eyelid, facial pain and headache, and nonorganic disease. Volume 3 covers degenerative, metabolic, infectious, inflammatory, and demyelinating diseases.
