The eyelids develop from ectoderm and from mesoderm. This evolution passes through distinct phases of maturation. Contemporaneously, the anterior segment of the eye takes form. The role of the amniotic fluid in the development of the eyelids is considered. The purpose of this report is to describe the development of the eyelids. The evolution of the eyelids from early embryonic life through different stages of development to term is examined.
The most comprehensive series dealing with the intracranial complications of transorbital stab wounds is that of Birch-Hirschfeld (I 930), who collected I 69 cases from the literature and added three of his own.
