Three ERG recordings, adapted from the guidelines of ERG recording in dogs/ were performed: 1) scotopic (dim-light) mixed rod and cone response, 2) photopic (bright light) cone response, and 3) photopic flicker response.
ERG was done which showed depressed photopic response in both eyes and depressed scotopic response in left eye.
This lens has normal contrast sensitivity range between photopic and it has reduced contrast sensitivity range in mesopic conditions.

Produced by photographer Nick Risinger and software developer Chris Laurel, the app features Risinger's seminal all-sky color Photopic Sky Survey (S&T: Feb.
The scotopic and photopic electroretinogram (ERG) response extinguished in both eyes.
Scotopic and photopic ERGs were recorded from 3- and 12-month-old C3-deficient and WT mice (n = 10 mice, for each group of animals).
With the above in mind, we sought to determine the contribution of OPs to the building of the photopic ERG waveform obtained from normal subjects and patients and to examine whether a signal mostly composed of OPs could also exist.
Markedly reduced b:a ratio in the single flash photopic ERG with additional a-wave delay is the most suggestive feature of Batten disease [7].
True to its name, true color combines appropriately scaled red-, green-, and blue-band reflectance values to form imagery that approximates the response of normal human photopic (daytime) vision.
