Current Concepts in Mechanisms, Diagnoses, and Management

• Gebundenes Buch

Produktbeschreibung

This book describes, illustrates, and shares our current understanding, evaluation, and treatments of nystagmus in infancy and childhood. Nystagmus in Infancy and Childhood will provide clinicians with algorithms for examination, descriptions of diagnostic techniques, and medical, surgical, and alternative treatments of the visual system in infants and children with nystagmus.
