A Humphrey automated perimeter was used to measure the central 24 degrees
of vision with static threshold targets and the peripheral field with two
automatic kinetic stimuli in 100 eyes of 100 patients with glaucoma or a
suspicion of glaucoma and to compare the additional information gained with
the peripheral tests. The peripheral visual field supported the diagnosis
made with central field testing in approximately one third of the eyes and
added additional diagnostic information in another fourth of the cases. In
4% of patients a normal central field was associated with a glaucomatous
peripheral defect. Virtually all peripheral defects were in the nasal
quadrant, and the more sensitive isopter uncovered the vast majority of the
defects.
