• We determined the static visual thresholds within 15° of fixation of 36 patients with elevated intraocular pressures but normal visual fields and compared the result with 36 controls matched for age and sex. We found no difference in the mean threshold level between the two groups. We did find a tendency for the patients with elevated IOPs to have greater variability or scatter of their threshold responses close to fixation. We also found the patients had larger cup to disc ratios than the controls.
