Perimetry, which at the same time laid the foundation for the development of more accurate modern perimeters. Since then, Louisesloan first recognized the importance of static threshold perimeters. Harms and Aulhorn provided a complementary statement perimetry to dynamic perimetry. They designed the Tubinger manual perimeter meter, which can perform both dynamic and static perimetry. Armaly introduced the concept of overthreshold screening, and he also proposed vulnerable areas of the visual field in glaucoma. In the 1960s, Dubois-Poulsen and Magis first tried to invent an automatic dynamic perimeter, but were hampered by technical problems. Using a computer and television, Lynn and Atee demonstrated the first automatic static perimeter in 1969. Since then, the automatic static perimeter has evolved and been continuously improved.
