Background:

Electroretinography (ERG) is a noninvasive method to evaluate retinal neuronal function.
ERG waveforms provide quantitative measures of retinal health in both normal and diseased states.
Specific ERG techniques allow for the isolation of rod and cone pathway contributions to vision.

Purpose of the Study:

To describe common full-field electroretinography techniques.
To explain how to isolate and compare rod-driven and cone-driven retinal function.
To highlight the measurement of inner retinal neuronal activity.

Main Methods:

Utilizing full-field electroretinography.
Employing scotopic flash, photopic flash, and flicker ERG protocols.
Analyzing electroretinogram (ERG) waveforms.

Main Results:

Demonstrated ability to isolate rod and cone pathway functions.
Quantified retinal function using ERG.
Showcased measurement of inner retinal neuronal activity (bipolar and ganglion cells).

Conclusions:

Full-field ERG techniques effectively differentiate rod and cone function.
ERG is a valuable tool for assessing retinal health and disease in rodent models.
Inner retinal function can be assessed using specific ERG protocols.
