SCOTOPIC vs. PHOTOPIC
ثبت نشده
چکیده
Over the last decade, a series of experiments sponsored by the U.S. Department of Energy showed that rods play a role in vision in lighting conditions typical of the workplace. The tests took place in realistic environments with typical interior lighting and task conditions. The tests showed that both vision and lighting energy efficiency would be improved if lighting practice accounted for the role of the rods in performing tasks in the workplace.

Prismatic adaptation under scotopic and photopic conditions.
Prismatic rearrangement experiments were performed under scotopic and photopic conditions by suitably darkor light-adapted .S's. Adaptation to prismatic displacement was highly significant when exposure and test procedures were carried out under scotopic as well as photopic conditions. Transfer experiments suggest that scotopically induced adaptation can be demonstrated under both scotopic and ...
متن کاملScotopic and Photopic Microperimetry in Patients With Reticular Drusen and Age-Related Macular Degeneration.
IMPORTANCE Clinical observations suggest that patients with age-related macular degeneration (AMD) have vision problems, particularly in dim light conditions. Previous studies on structural-functional analysis in patients with AMD with reticular drusen (RDR) have focused on photopic sensitivity testing but have not specifically assessed scotopic function. OBJECTIVE To evaluate retinal functio...
متن کاملEffects of Chronic and Acute Intraocular Pressure Elevation on Scotopic and Photopic Contrast Sensitivity in Mice
PURPOSE To compare the impact of intraocular pressure (IOP) elevation on scotopic and photopic contrast sensitivity in mice. METHODS We chronically elevated the IOP of wild-type mice via injection of polystyrene beads or acutely via injection of highly cohesive sodium hyaluronate. Some eyes with chronically elevated IOP were treated with either topical brimonidine tartrate 0.1% or brinzolamid...
متن کاملPhotopic and scotopic flicker sensitivity of a rod monochromat.
The sensitivity to sine-wave flicker of a rod monochromat was compared with that of a normal subject at photopic and scotopic levels of luminance. The sensitivity of the rod monochromat in the low-frequency region (below 3 Hz at scotopic levels and below 12 to 14 Hz at photopic levels) was found to be superior to that of the control. This superiority was most pronounced at photopic levels, wher...
متن کاملPhotopic and scotopic multifocal pupillographic responses in age-related macular degeneration
We compared photopic and scotopic multifocal pupillographic stimuli in age-related macular degeneration (AMD). Both eyes of 18 normal and 14 AMD subjects were tested with four stimulus variants presented at photopic and 126 times lower luminances. The multifocal stimuli presented 24 test regions/eye to the central 60°. The stimulus variants had two different check sizes, and when presented eith...
متن کاملAsymmetrical Functional Deficits of ON and OFF Retinal Processing in the mdx3Cv Mouse Model of Duchenne Muscular Dystrophy.
Purpose The dystrophin mouse mutant mdx3Cv exhibits scotopic electroretinograpic (ERG) abnormalities, which resemble clinical changes observed in Duchenne muscular dystrophy (DMD) patients. In the present study, ERGs obtained from mdx3Cv and their wild-type littermates under scotopic, mesopic, and photopic conditions were analyzed to provide further insight on the affected retinal pathways, and...
