Perimetry 1 1.

The 3 dimensional area of a subjects surrounding that can be seen at any one time around an object of fixation. Traquair defined visual field as “ island or hill of vision surrounded by the sea of darkness” The shape of hill of vision correlates to density of photoreceptors and their receptive field sizes.

The Humphrey uses fixed points of light which are shown at different intensity levels.

Humphrey Field Analyzers are used by more eye perimetry using the Humphrey Field Analyzer, which are the most popular perimeters in their respective categories. The basic concepts of these two systems can be applied to other kinetic or automated systems.
