Abstract
-
The purpose of this study was to standardize normal EOG values in Koreans. The subject were 23 normal Koreans varying in age 16-40 yrs with no ocular abnormality or disease. EOG was recorded by Life-Tech instrument Model 7310 ERG/EOG stimulator, Model 7101 ERG/EOG analyzer. The result were as follows. Dark trough potential was 235.65 +/- 71.59 uV, Light Peak Potential was 402.60 +/- 103.09 uV, EOG ratio(Lp/Dt) was 1.74 +/- 0.23, Dark trough time was 14-15 minutes, and light peak time was 10 minutes.
