Electro‐oculography was performed on 120 normal subjects (240 eyes) between 10 and 69 years of age, with an even sex and age distribution. E. O. G. ratio showed a significant sex difference ( P < 0.01), with females having higher E. O. G. ratios than males. There was a significant negative linear correlation between E. O. G. ratio and age in females ( P < 0.01), but none in males. Close correlation in E. O. G. ratio was found between right and left eyes ( P < 0.01), and 95 % of subjects showed a difference of 80 or less between right and left eyes. New normal limits of E. O. G. ratio are proposed. These are 150 to 290 for all males and for females of 50 or more years of age, and 170 to 342 for females below the age of 50 years.
