This book presents the salient features of optic nerve disorders, enc- passing optic neuritis, papilledema, ischemic optic neuropathies, c- pressive and in? ltrative optic neuropathies, traumatic optic neuropathies, nutritional and toxic optic neuropathies, hereditary optic neuropathies, and optic disc tumors. Chapters 1 to 9 outline key clinical aspects of each of these disorders. Chapter 10 illustrates some newer applications of optical coherence tomography (OCT) in monitoring optic nerve-related processes causing retinal nerve ? ber layer loss and in ruling out retinal disorders. Chapter 11 discusses the adjunctive role of visual evoked potential (VEP), multifocal VEP, electroretinogram (ERG), and mul- focal ERG in the diagnosis of more challenging visual problems, es- cially in distinguishing them from macular disorders and psychogenic etiologies. Although there are excellent textbooks covering various aspects of neuro-ophthalmology, this book is intended for any physician, including ophthalmologists, neurologists, and neurosurgeons. Fellows, residents, and medical students can acquire an up-to-date knowledge base to better help their patients with optic nerve disorders. It is a unique reference that combines the applications of some newer diagnostic techniques with the symptoms and signs approach to visual loss in a useful and practical format.
