Talk Description
Jillian Campbell presents on Interpreting Corneal Topography - An Optometrists' Guide
Duration: 30 minutes
Synopsis: This lecture provides a practical, clinically focused overview of corneal topography for everyday optometry practice. We will revisit the principles behind Placido disc, Scheimpflug and OCT-based imaging, then explore how to interpret key maps including axial, tangential, elevation and pachymetry plots.
Attendees will learn how to recognise normal versus abnormal corneal patterns, identify early keratoconus, and distinguish between irregular astigmatism, ectasia and post-surgical changes. Real patient cases will highlight how topography guides decision-making in refractive surgery referrals, contact lens fitting, and monitoring corneal disease. The session is designed to equip optometrists with confidence in both the basics and the nuances of corneal shape assessment.

Learning Objectives
By the end of this session, delegates should be able to:
- Understand the principles behind different corneal topography systems
- Accurately interpret axial, tangential, elevation and pachymetry maps.
- Recognise normal corneal patterns versus early and advanced keratoconus.
- Differentiate irregular astigmatism, corneal ectasia and post-surgical changes.
- Apply corneal topography findings to refractive surgery referrals and co-management.
- Use topography to guide contact lens fitting decisions in routine and complex cases.
- Monitor disease progression and treatment outcomes using corneal mapping.
