Perimeter, manual

Definition

A mains electricity (AC-powered), manually-operated, diagnostic ophthalmic instrument intended for assessing the extent of the patient's peripheral visual field. Small luminous points (spots) are displayed by manual operation in various random positions and patient response is recorded. A preprinted card (chart) is marked to show the resulting curve of the visual field. Such types include Goldmann perimeters.
