Series Statement: [IOP release 6]

Content: This book presents the latest achievements and research works of intraocular pressure measurement by the air-puff method presented by experts in the field. It is about tonometers, in particular using the air-puff method. These methods are used, for example, by the Corvis ST. Owing to the ultra-high-speed Scheimpflug camera, which records corneal deformation being the response to an air-puff. In this connection, this book is interdisciplinary in: new methods of image analysis and processing; new engineering methods used in devices; method reducing measurement (intraocular pressure) errors; the change in the blood pulsation phase during measurement affects the results in different ways; other IOP measurement methods (using the air-puff method); medical and engineering problems in air-puff method. This book is recommended reading for those involved in the analysis and processing of images and wanting to expand their knowledge of contemporary diagnostic methods and modern methods of image analysis. Part of IOP Series in Medical and Biological Image Analysis
