Summary of Content

Examination of the structure of the eye and adnexa. Recording of clinical findings by photgraphs and diagrammatic means. The theoretical and practical basis for investigation of a variety of ocular anatomical and physiological parameters. Interpretation of the significance of the results of investigative procedures and criteria for referral for further medical investigation

Learning Outcomes

On completion of this module, students should be able to:Understand the theoretical principles of ocular measurement and obtain clinically valid measures of the ocular components.Examine the structures of the eye using a variety of techniques and obtain accurate photographic records of ocular structures.Measure the extent of any visual field loss and interpret the degree and pattern of loss in a clinical context by graphical and statistical means.Obtain valid clinical measurements of the intraocular pressure using a variety of contact & non-contact techniques and interpret and evaluate the clinical significance of results.Generate and systematically pursue a line of investigative enquiry independently.Demonstrate an enquiring and analytical approach to investigation of visual function.Demonstrate appropriate skills to successfully engage in continuing professional development through lifelong learning

Teaching / Learning Strategy

This module comprises a programme of lectures and practical clinical sessions. Practical clinical sessions will provide students with the opportunity to consolidate the theoretical knowledge gained in lectures, and enable students to develop a range of clinical skills for the investigation of the normal and abnormal eye.
