Module 3 - Supplementary Testing

Sometimes a patient will require additional testing to rule out, diagnose or monitor certain eye conditions or diseases. This module covers some of the most common supplementary testing procedures and equipment including: visual fields, digital imaging systems (OCT, HRT, corneal topography, fundus photography), and pachymetry. 

Upon completion of this module, the optometric assistant will be able to: 

  • Explain how visual field testing detects and monitors visual pathway defects. 
  • Compare common visual field testing methods and their uses. 
  • Identify key clinical uses of corneal topography.
  • Describe pachymetry and its role in measuring corneal thickness and assessing glaucoma, corneal edema, keratoconus, and refractive surgery suitability. 
  • Demonstrate appropriate preparation, capture, and documentation for fundus photography. 
  • Differentiate digital imaging systems by function and clinical application.
