Summary

The provider performs pattern electroretinography (PERG), an electrophysiologic technology to assess the function of both the retina and macula. The retina is tissue at the back of the eye that is sensitive to light and helps in visual image formation, and the macula is the point of sharpest vision on the retina. The provider also interprets the findings of the PERG and prepares a report.
