[The importance of the eyelids for ophthalmodynamographic recordings-- an oscillographic study before and after total plastic reconstruction of the eyelids (authors transl)].

Ophthalmodynamography (ODG) of an empty orbit apart from a covering of atrophic skin 1mm thick revealed only one twentieth of the pluse amplitude of the contralateral normal orbital oscillographic waves. After total plastic surgical reconstruction of the lids, isolated oscillographiy of the eyelids was performed for the first time. The pulse amplitude now reached about 1/4 of that of the contralateral side. It is concluded that these reconstituted eyelids contribute at least 25% towards the volume and 25% towards the oscillographic pulse wave amplitude on performing ODG in the usual manner. These values could well be exceeded in normal lids on account of their better blood supply.
