Visual Field Test

Visual Field Test

Visual field is your field of view when you look straight ahead without moving your eyes or head. Points of light of varying intensity at different locations are flashed until you can see them to evaluate the size and sensitivity of your visual field.

Computerized Projection Perimeter utilizes computer algorithms to determine the sensitivity of the optic nerves in perceiving flashing light of different brightness levels at fixed test locations and evaluate for visual field norms or defects.

Visual field defects may lead to car accidents or poor sports performance but it may also indicate serious issues in the eye or the brain.

Clinically, visual field tests are conducted to test the function of the visual system related to the optic nerves and the brain, for example, when glaucoma or a brain tumour is suspected. The location, size and shape of the blind spots may provide the clue for a diagnosis.
