The evaluation of 116 normal ratios with a 10 ft. lambert ganzfield illumination confirmed that ratios over 200% can be considered as normal. Individual variation led to the proposed classification of 175% to 200% as being low or suspicious. Ratios below 175% are abnormal and are useful in establishing the diagnosis of pathology.
