[Data bank for analysis of the normal visual field using the 30/1 central program of the automated Humphrey...

Quantification is one of the most interesting improvements given by the automated perimetry. Such approach has, for instance, permitted the development by J. Flammer of quantification indices for JO program of Octopus. However, for working this concept needs quantitative data on normal visual field. Using an Humphrey automated perimeter and central threshold 30/1 program, we have gathered with the "quantification" program ley Thot Informatique, normal data on 178 visual field from 117 normal outpatients attending Ophthalmology Department of the Angers Hospital (58 females-59 males). Then, those data have been ranked by age, to obtain reference visual fields and corresponding standard-deviation fields. There is a decrease in visual sensitivity in the superior part of the 30 degrees field when compared to inferior. There is a decrease in visual sensitivity with ageing-about 1 dB by decade-more in the peripheral part of the 30 degrees field than in the central part. Standard deviation visual field is of considerable interest to valid pathologic visual field detects. There is an increase standard deviation for the peripheral part of the 30 degrees field. Finally, standard deviation is increased in elderly people as compared to younger.
