Visual Fields

Visual Field is the total area in which objects can be seen in the peripheral vision while the eye is focused on a central point.

Confrontation Visual Field Exam is a quick and basic evaluation of the visual field done by an examiner sitting directly infront of you. With one eye covered, you are asked to look at the examiner's eye and tell when you can see the examiners hand.

Automated Perimetry is when you sit infront of a concave dome and stare at a central target within the dome. A computer-driven program flashes a small light in different locations within the dome's surface and you press a button when you see the small lights in your peripheral vision. Your responses are compared to age-matched controls to determine the presence of defects within the visual field.
