For the scotopic mixed rod and cone and photopic
cone responses, the data obtained were the a-wave and b-wave implicit time and amplitude.
(iii) Phenotype 3: diffuse macular, peripapillary, and peripheral RPE atrophy and hyperfluorescent dots, altered photopic
and scotopic responses on full-field ERG.
With the spectral goggles, a see-through photopic
transmission rate of 75% can be achieved, with the possibility to block unwanted rays coming from laser pointers at 532 nm.
Caption: The planetarium app Sky Guide for iOS devices incorporates several all-sky survey mosaics into the appearance, including coauthor Nick Risinger's own Photopic
Sky Survey (left).
The ERG recordings, under both scotopic and photopic
conditions, in C3-/- and WT mice at 12 months of age, were significantly lower (p <0.01) than those observed in 3-month-old gender-matched animals.
Analysis was performed on photopic
ERGs (bandwidth: 1-300 Hz; flash intensities: -2.23 to 2.64 log cd x sec x [m.sup.-2] in 21 steps of ~0.2 log-unit; background: 30 cd x [m.sup.-2]; averages of 10 to 300 flashes per response) obtained from 40 normal subjects.
* For circadian health applications, summary data of melanopic and photopic
lumens and efficacy.
3) the scotopic b/a ratio was lower than normal range and photopic
b/a ratio was higher than normal range.
Stereo-acuity Ability to perceive spatial TNO Stereo depth; it is a binocular test faculty which is achieved through horizontally disparate images for right & left eyes of the same object Test Illumination, Scale lux Static visual acuity 480 Letter score (theoretical range: 0 to 100) Refractive error 12 Spherical and cylindrical error with axis (Diopter) Contrast sensitivity 12 Log Unit Ocular alignment Photopic
[greater Prism Diopter than or equal to] 25 Stereo-acuity 800 Range: 15 to 480 s/arc Test Description Static visual acuity Monocular and binocular visual acuity and best spectacle-corrected visual acuity (BSCVA) are assessed and recorded during archery Refractive error This measurement is performed with and without cycloplegia.
Neurovision studies have reported behavioral changes related to ingestion of alcohol, for example: (i) changes in perception and detection of asymmetry of facial expressions in both men and women (Oinonen & Sterniczuk, 2007); (ii) change in luminance processing speed in photopic
and scotopic levels (Khan & Timney, 2007; Puell & Barrio, 2008).
The proportion of shorter wavelength 'scotopic' light relative to longer wavelength 'photopic
' light is known as the S/P ratio.
vision, our fovea is more sensitive to the red wavelength while the blue wavelength influences scotopic vision.
