Peripheral refractive error correction did not significantly impact automated perimetric sensitivity in normal eyes. This study found no change in visual field sensitivity when correcting for refractive errors at different visual field locations.

Area of Science:

  • Ophthalmology
  • Visual Science
  • Optometry

Background:

  • Peripheral refractive error can potentially influence visual field testing.
  • Automated perimetry is a key tool for assessing visual field sensitivity.

Purpose of the Study:

  • To investigate the effect of peripheral refractive error correction on automated perimetric sensitivity.
  • To determine if correcting peripheral refractive error improves the accuracy of visual field testing.

Main Methods:

  • 10 clinically normal observers underwent automated perimetry.
  • Peripheral refractive error was measured at 0, 20, and 40 degrees temporal eccentricity.
  • Perimetric sensitivity was assessed with and without peripheral refractive correction using the Octopus 201 perimeter.

Main Results:

  • Peripheral refractive correction did not influence perimetric sensitivity at the tested eccentricities.
  • No significant difference in visual field sensitivity was observed with or without correction.

Conclusions:

  • Peripheral refractive error correction does not appear to affect automated perimetric sensitivity in clinically normal individuals.
  • Current automated perimetry methods may be robust to typical peripheral refractive errors.
