Intracranial injury, caused by a transorbital penetrating object, is a neglected topic in neurosurgery. With few exceptions, only occasional publications, often containing merely case histories, are present in the literature. Through a perusal of the world literature -- for the first time -- the author has collected and combined all available and relevant information, trying to give a thorough description of this rare, but extremely dangerous injury. This book is a major and definitive contribution to neurosurgery, but is also of importance to ophthalmology, neurology, traumatology, neuro-radiology and pediatrics.
