Publisher's Synopsis
About 50 million people are blind world-wide. 20 million are blind from a single cause - cataract, and 75% are blind from conditions that are preventable or treatable.;The majority of the world's blind live in developing countries where health care and medical resources are scarce. The technology for preventing blindness in developing countries is simple and eye care can be performed by specially trained health workers supervised by ophthalmologists, often in remote places with limited supplies and equipment.;This book is intended as a reference text for students and teachers of eye care and blindness prevention. The emphasis is on efficient and inexpensive methods of diagnosis, treatment and prevention programmes.;This second edition has been revised and expanded. The sections on onchocerciasis, including Metzican, nutrition and xerophtalmia have been updated and the chapter on trachoma has been revised to include the WHO scheme for grading trachoma.
