How is a visual field examination for an eye done?
A doctor has provided 1 answer
A perimeter: Visual fields are mapped out using a device called a perimeter. Most are computer driven but a few a done manually. You will asked to fixate a target with an exposed eye (the other is covered) and identify the target spot somewhere in the dome of the machine. Multiple points are tested and recorded. This produces a MAP of retinal sensitivity, useful for analyzing the vision of your retina.
