In summary, although influencing factors such as pupil size and accommodation status impose challenges to obtaining reliable aberration measurements in children, our study showed that satisfactory intra- and intersession repeatability could be achieved under
scotopic conditions by using iTrace.
7 and 8 than the difference between the photopic and
scotopic efficacy functions.
Our results show drat GLE in mice with [BPb] at the current low level of concern (CDC 1991) produced persistent retinal alterations characterized by proportional increases in rod and rod BC neurogenesis that likely underlie the observed
scotopic ERG super-normality (Fox et al.
This is the first study to compare the
scotopic visual functions of Pacific bluefin tuna with those of other fishes by ERG.
Various lamps emit light with distinctly different spectra, and not all are a good match to the
scotopic sensitivity range.
Civil twilight therefore represents an important transition time when the visual system shifts from photopic (day) to
scotopic functioning.
Atrophy of the choriocapillaris and outer retinal layers were evident on OCT, photopic and
scotopic responses were attenuated on flash electroretinography (ERG), and responses were also minimal in pattern and multifocal ERG (see pages 298-301).
The first example of varying perceptual accuracy can be observed in
scotopic (rod-mediated) conditions.
Preoperative evaluation consisted of uncorrected visual acuity for both--distance and near; best spectacle corrected visual acuity, manifest and cycloplegic refraction, ocular dominance, keratometry, applanation tonometry,
scotopic pupillary size, tear film break up time, blinking rate, Schirmer test when necessary, pachymetry, slitlamp examination and computerized video keratography.
The
scotopic spectral luminous efficiency V'([lambda]) is based on the rod photoreceptor responsivity of the eye.
