Electroretinography (ERG) is a diagnostic test used to evaluate the electrical activity of the retina in response to light stimuli. This non-invasive procedure provides valuable information about the function of the retina, helping to diagnose a variety of retinal diseases and conditions.
How Does Electroretinography Work?
During an ERG test, electrodes are placed on the surface of the eye to measure the electrical signals generated by the retina in response to light. The patient is typically asked to sit in a dark room with their eyes dilated before the test begins. A series of flashes of light are then presented to the eye, triggering a response in the retina that is detected by the electrodes.
Types of Electroretinography
There are two main types of ERG tests: scotopic and photopic. Scotopic ERG is performed in the dark to evaluate the function of the rod cells in the retina, which are responsible for night vision. Photopic ERG, on the other hand, is done in a lit room to assess the function of the cone cells, which are responsible for color vision and visual acuity.
Applications of Electroretinography
ERG is commonly used to diagnose a variety of retinal conditions, including retinitis pigmentosa, macular degeneration, and diabetic retinopathy. It can also be used to monitor the progression of these diseases and evaluate the effectiveness of treatment over time.
Overall, electroretinography is a valuable tool in the field of ophthalmology, providing important insights into the function of the retina and helping to guide patient care and treatment decisions.
Electroretinography Examples
- The ophthalmologist used electroretinography to diagnose the patient's retinal disorder.

- Electroretinography is a valuable tool for assessing the health of the retina in patients with diabetes.
- The veterinary ophthalmologist performed electroretinography on the dog to monitor its retinal health.
- A clinical trial is underway to determine the efficacy of electroretinography in detecting early signs of macular degeneration.
- Electroretinography can help differentiate between different types of inherited retinal diseases.
- The neurologist recommended electroretinography as part of the diagnostic workup for the patient's vision problems.
- Electroretinography is commonly used in research settings to study the visual system in various animal models.
- The technician carefully positioned the electrodes for the electroretinography test to ensure accurate results.
- Results from the electroretinography test indicated abnormalities in the patient's rod and cone function.
