内容説明
This new publication deals almost exclusively with automated perimetry. Emphasis is on technical aspects of administering the automated test with skill, as well as on skilful interpretation of the result based on an understanding of the text. "Automated Static Perimetry" is a thorough, pragmatic, and up-to-date resource for those learning perimetry for the first time in a clinical setting where automated perimetry predominates, as well as a valuable resource for individuals converting to the use of automated perimetry from manual methods.
