Summary:
Has finished the article [on the action of the eyelids in Ned. Arch. Geneeskd. & Natuurkd. 5 (1870), also see 7238]; summarises: the occlusion of the eyelids protects the vessels, and the eye itself, against the danger of pressure caused by excessive expiratory action. The weakness of the conclusion is that the extent of the danger caused by the pressure to the normal state of the eye is not precisely known.
