Description
We placed negative electrodes on the body and positive electrodes at the medial and lateral canthi, measured their potentials separately, evaluated their characteristics, and analyzed cross-talk. We recorded EOG in 6 normal subjects and found the following. The potential at the medial was lower than that at the lateral canthus in the bilateral eyes. The polarity of waves at the lateral was reverse to that at the medial canthus in the bilateral eyes. We recorded EOG in 6 patients with unilateral anophthalmia and found the following. On the anophthalmia side, the potential at the lateral was considerably lower than that at the medial canthus. The polarity of the potential was the same between the medial and lateral canthi. The mean cross-talk to the medial canthus on the anophthalmia side was 8.7%- 54.0% of the potential at the medial canthus on the normal side. The mean cross-talk to the lateral canthus on the anophthalmia side was 4.4%-16.9%. The influence of cross-talk of the other eye was marked at the medial but slight at the lateral canthus. In EOG recording, results with minimum errors due to cross-talk can be obtained by paying attention to the potential at the lateral canthus.
