BACKGROUND An objective and noninvasive examination of pupil size variability can be used to assess the activity of the autonomous nervous system. We designed a system that enables binocular, fast, and accurate recordings of different types of pupil variabilities, which are synchronous with other biosignals. This type of measurement system is needed to(More)
Background: The waveforms of the pupillary light reflex (PLR) can be analyzed in a diagnostic test that allows for differentiation between disorders affecting photoreceptors and disorders affecting retinal ganglion cells, using various signal processing techniques. This procedure has been used on both healthy subjects and patients with age-related macular(More)
—This paper examines the possibility of detecting 2 conditions which cause vision to deteriorate: Aged-Related Mac-ular Degeneration (AMD), and the effects of aging on eyes using the features of PLR waveforms. These features were extracted using Fourier descriptors of PLR waveform shapes, weighted amplitudes of the waveforms, and a balanced combination of(More)
