Abstract
Measurement science for the sense of sight has exploited advanced computer technology to emerge as an exciting technical and medical discipline. The chapter presents a full survey of sight measurement methods describing procedures, engineering principles, technological construction and diagnostic motivation. The chapter opens with the classical measurement tests for visual acuity, field of vision, and intraocular pressure, followed by the techniques used in biometry and ocular examinations.
The more advanced technological fields of optical coherence tomography and ocular electrophysiology are described in the last two sections of the chapter. These techniques have developed in sophistication over the last twenty years or so. Advances in computer visualisation software, laser technology, data collection, signal processing algorithms and human-sensor interface systems have all been used to provide complex and accurate measurements and visualisations of the eye physiology and functions for clinical diagnosis. The chapter presents a state-of-the-art review of these sight measurement advances.
