- ‘Features of a severe case include palpebral redness and swelling, obvious congestion of bulbar conjunctiva possibly accompanied with petechial hemorrhages and increase of mucus secretions at the inner canthus.’
- ‘Additional electrodes were placed at the outer canthus of each eye to obtain the subject's EOG, which was used to facilitate artifact scoring.’
