Pattern Electroretinography Testing / ERG Testing

CRH Vision is proud to be the first eye care practice in Chester County offering Pattern Electroretinography Testing / ERG Testing in-office. ERG measures the function of your retina – the light-sensitive layer at the back of your eye. When light from an image enters the eye, it is converted into electrical energy by specialized cells in the retina. These cells send electrical impulses through the optic nerve to the brain where the image is processed. The Diopsys NOVA-ERG test records how well the cells of the retina are conveying electrical impulses within the eye.

ERG results have ben demonstrated to aid in the diagnosis and treatment planning of many vision disorders such as; glaucoma, age-related macular degeneration, retinal dystrophies and much more.
