Service Description:

The Visual Fields Department undertakes the testing of a patient's visual field or 'Perimetry'.

Perimetry testing is crucial in the screening, diagnosis and monitoring of various eye, retinal, optic nerve and brain disorders.

A visual fields test uses varying intensities of light. It works by systematically measuring differential light sensitivity in the visual field by detecting the presence of 'test targets' on a defined background.

Testing can be performed in a number of ways including:

  • Clinical tests using 'confrontational' field testing to assess a wider area of the visual field. The patient's gaze is fixed and objects appear at various places in their visual field.
  • Perimetry, which is able to assess and record the visual field. The Visual Fields Department at The Manchester Royal Eye Hospital uses a range of 'kinetic perimetry; including the Goldmann bowl perimiter and the Humphrey visual field analysers. This involves using a mobile stimulus moved by a perimetrist and is useful for testing and recording the outer limits of a patient's vision with the eye kept in a static position.
  • Threshold static perimetry is generally done using automated equipment and is specifically used for rapid screening and follow up of diseases, scotomas (blind spots), loss of peripheral vision and more subtle vision loss.
