The number of the millions of blind in the world continues to grow, causing needless social and economic deprivation. Most of these blind can be cured, and much of the remainder prevented if all people had access to the simple and effective interventions that already exist. In this newly revised fourth edition of 'Eye Care in Developing Nations', the author describes in practical detail, what these interventions consist of and how they can be readily implemented. In this expanded and updated edition all chapters have been revised to reflect developments in public health and in medical and surgical treatments and techniques.
