Learning outcomes

  1. Prepare patients and the clinical environment for psychophysical assessment of vision
  2. Perform assessment of visual acuity in children and adults, including adults who are illiterate, have learning difficulties, or who are non-English speaking, with Snellen/logMAR and contrast sensitivity
  3. Assess colour vision with Ishihara charts and at least one other form of colour vision assessment, eg D15, City Plates
  4. Assess the visual field with standard automated perimetry and other methods, which may include kinetic perimetry, microperimetry, automated Amsler grid testing and frequency doubling perimetry
  5. Interpret and report results in the correct clinical context
