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. This is the handyman’s guide to delivering eye services to low-resource populations, whether they are pockets of poverty in otherwise affluent countries or broadly deprived populations living in the developing world. Demand for the first three editions from around the world has proved this book’s value. 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. The book’s value is further enhanced in the fourth edition by the greater emphasis given to clinical ophthalmology and the provision for the first time of colour photos and diagrams throughout.
