Data from the initial examination of 12 patients who developed glaucomatous field loss while under observation were examined to determine which parameters showed an increased prevalence in the population. These parameters were then tested in a prospective manner to learn their predictive value in 50 patients with ocular hypertension (intraocular pressure ≥ 22 mm Hg and no field loss) who were followed up without therapy for a minimum of five years. The individual parameters were not good predictive indicators. The use of several parameters together, however, improved the ability to predict in which eyes field loss would develop.
