Pupillometer* for use during anasthesia

Abstract

This paper presents the design for a pupillometer based on a fixed focal length microscope; it is suitable for use during anasthesia. The pupillometer has been tested and found to give reliable results. A certain amount of practice is necessary to make measurements quickly. The pupillometer was designed to allow the study of pupil diameter in relation to ‘depth of anasthesia’. Copyright © 1984, Wiley Blackwell. All rights reserved
