Competency information


Perform on a volunteer adult

  • LogMAR visual acuity with and without spectacles
  • Ishihara colour vision test
  • an automated static visual field or a confrontational field.


  • normal ocular and retinal images
  • normal ERG traces.


  • Relevant protocols and standard operating procedures (SOPs) for the 
  • investigations to be performed.
  • Anatomy and physiology of the eye, and visual pathways and pupillary pathways.
  • Range of clinical conditions that may give rise to defects:
    • in the red reflex ( e.g. cataract, retinal detachment)
    • visual acuity (e.g. maculopathy, optic nerve dysfunction)
    • colour vision (e.g. optic nerve dysfunction, congenital colour vision defects)
    • visual field (e.g. chiasmal compression, hemisphere dysfunction) and the relevance of these tests to these conditions.
  • How to instruct and reassure the patient to maximise effectiveness and compliance.
  • Methods of judging reliability of patient response.
