Visual field tests measure the peripheral or ‘side’ vision of a person. They are used for diabetic and glaucoma patients, and drivers who are referred to us by the DVLA.

The test, consisting of 15-45 minutes, requires the person to sit before a computerised machine, with their head positioned on a chin rest, looking forward towards a centralised point. Lights of varying brightness are flashed on sporadically, and the person is asked to press a button each time they see it.

A mean result is taken from the test to assess whether vision is worsening. If so, for glaucoma patients, pressure in the eyes will need to be reduced with the aid of drops.

Visual field tests can also aid ophthalmologists in diagnosing pathological conditions such as cancers, tumours and neurological illness.
