Normalization Of The ERG: Age Group 26-35.

The skill required for ERG diagnosis is the ability to identify an abnormal response 1 versus a normal one. One must be able to compare a patient against a group of normal
subjects of about the same age that have been tested under similar conditions.
Standards have been developed in regard to aquiring normal ranges for each individual laboratory. The International Society for Clinical Electrophysiology of
Vision (ISCEV) have reviewed and updated these standards including instrumentation/ recording procedures and measurement in clinical electroretinography. The most recent
standard was set in 1987 and includes guidelines for Basic Technology/ Clinical Protocol and description of the 5 standard ERG responses. The following testing methods and results have been accomplished in order to comply with the ISCEV requirement that each laboratory establish normal values for its individual equipment and patient population.
