Preface

For almost six decades, General Ophthalmology has served as a concise, current, and authoritative review of the subject for medical students, ophthalmology residents, practicing ophthalmologists, nurses, optometrists, and colleagues in other fields of medicine and surgery, as well as health-related professionals. The nineteenth edition has been revised and updated in keeping with that goal. It contains the following changes from the eighteenth edition:

• All relevant illustrations in color

• Major revision of Chapters 6 (Cornea), 10 (Retina), 13 (Orbit), 14 (Neuro-Ophthalmology), 16 (Immunologic Diseases of the Eye), 20 (Causes and Prevention of Vision Loss) and 23 (Lasers in Ophthalmology).
