The book presents the most common problems seen in neuro-ophthalmology in a case-based learning format that provides rapid access and is easy to read. The user friendly format guides and stimulates the reader to identify the distinctive symptoms in the main complaint and history; to define the differentiating signs on neuro-ophthalmic exam; and to describe the key laboratory or neuroimaging in specific entities. It also challenges the reader to ask additional questions of themselves and others by providing an initial set of questions and answers on specific neuro-ophthalmologic topics.The questions chosen are meant to simulate “real world” questions in the clinic; the answers given serve to provide both the rationale for the correct answer and the explanations or reasons for the incorrect but plausible answers that might distract or mislead a clinician in specific neuro-ophthalmic cases.
