The retina is part of the central nervous system and is located at the back of the eye.
It contains two types of light sensory: rods and cones.
Rods see black and white and are important for sight in low light conditions and for peripheral vision.

Cones, on the other hand, see color.
Electroretinography provides a measurement of the rods and cones in the retina.
There was no difference in the cones' responses between the two groups.
What Do These Results Mean?
This knowledge may be helpful in future genetic testing and prevention research.
This may contribute to their functional impairment.
