An old-fashioned method to develop a map of a patient’s visual field. It can be used to diagnose various conditions such as eyelid droop and ocular hysteria. It involves hanging a black piece of cloth on the wall, while the patient sits facing the wall with an occluded eye. The patient is asked to report when they see a target on a stick brought from the periphery. The activity is repeated until a full visual field has been registered.
