What are the limitations of Electroretinography in Toxicology?
While ERG is a powerful tool, it does have limitations. The test primarily measures the aggregate electrical response of the retina and may not detect damage at the cellular level unless it is widespread. Additionally, ERG requires specialized equipment and expertise, which can limit its availability. Interpretation of results can also be complex, as multiple factors, including the patient's age and underlying health conditions, can influence the outcomes.
