Fatigue effect within 10 degrees visual field in automated perimetry
Ann Ophthalmol.
1993 Apr.
Abstract
We studied the effect of fatigue within a 10 degree visual field measured with automated perimetry in normal volunteers (10 eyes), patients who have recovered from optic neuritis with multiple sclerosis (10 eyes), and patients with glaucoma (10 eyes). Using an Octopus 201, the visual field was tested with Program 61, which was centered (0.0), and 25 test locations were determined three times. Eight of the 25 points were selected for the evaluation. The mean sensitivity of the eight points was compared among the three measurements. Normal subjects and patients with optic neuritis showed no effect of fatigue within the 10 degrees visual field, but the patients with glaucoma indicated fatigue during the third measurement.
