An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes.
These cells are known as rods and cones. They form part of the back of the eye known as the retina. There are around 120 million rods in the human eye and six to seven million cones.
The cones are responsible for the eye’s color sensitivity. They reside mostly in your eye’s macula. The rods are more sensitive to light than the cones, but they’re not more sensitive to color.
Your doctor may perform an ERG to determine if you have an inherited or acquired disorder of the retina, such as:
retinitis pigmentosa, which is a genetic disease causing loss of peripheral and night vision macular degeneration, which is a loss of vision due to the death of cells in the ma...Electroretinography | 合法醫療器材資訊網
