Abstract

Visual field evaluation is important in the detection, diagnosis and assessment of ophthalmologic and dysfunctions. Kohn and Clyenes were the first to appreciate that the pupil react to changes in the wavelength composition of the stimulus independently of luminance. Also, we have shown that the effective pupillary area changes at varying perimetric angles. Based on these studies a new technique is described to quantify pupillary response during a visual field examination, using a signal-image processing system associated with chromatic LEDs stimuli.
