Clinical Orthoptics (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Clinical Orthoptics has become established as a basic reference text providing fundamental information on anatomy, innervation and orthoptic investigation, plus diagnosis and management of strabismus, ocular motility and related disturbances. It is aimed at trainee ophthalmologists and orthoptic undergraduate students. Qualified orthoptists, general ophthalmologists and optometrists will also find valuable guidance in these pages. In this edition, the author has maintained the goal of producing a user-friendly, clinically relevant and succinct book, while revising it to reflect a variety of developments in the field. FEATURES * Essential reading for students of orthoptics and ophthalmolology * Now fully revised and updated * Generously illustrated with photographs and line drawings * Includes diagnostic aids, case reports, and helpful glossary
