Computerised Visual Field Assessment (Peripheral Vision Test)

This is a test which you may be advised to have if we are concerned that your peripheral vision might have been damaged. This is especially important if you have a family history of glaucoma, if you have had a stroke, or if you have unexplained headaches.

The test is carried out using a sophisticated computerised instrument called a Visual Field Analyser or Visual Field Screener. You are usually given a small handset on which there is a button. You look into the instrument, usually with one eye covered up, and simply press the button every time you see a flash of light.

The results of these tests can be analysed by computer and can be monitored over a long period of time to detect slight changes in your eyes' performance. The results can be analysed by complex computer programmes, and can be emailed to colleagues or hospital eye departments whenever necessary.

A very basic visual field test would be included in a standard eye examination: if you require computerised visual field testing, there will normally be a fee for this service.
