Questions and Answers

What is the main purpose of Orthoptists in assessing peripheral visual function?

  • To monitor the progression of visual field loss
  • To measure size and sensitivity of the visual field (correct)
  • To make decisions about the management of eye diseases
  • To determine resolution acuity

What is the main function of the visual field?

  • Assess visual pathway development
  • Gather information from the optic chiasm
  • Measure test reliability
  • Detect motion (correct)

What are the common principles of visual field assessment?

  • Occlusion of each eye, central steady fixation, and patient response when peripheral stimulus is detected (correct)
  • Measuring size (deg²), sensitivity (dB), and shape of the visual field
  • Binocular Esterman testing and automated perimetry
  • Confrontation, static threshold, and kinetic perimetry
