The title of this paper is somewhat ambiguous in that the eyelids are actually an integral part of the lacrimal system. A better definition might be that the lacrimal apparatus is made up of 3 parts: (1) the secretory system, consisting of the various glands; (2) the distributional system, consisting of the lids which not only carry the fluid to all parts of the conjunctival sac, but also furnish the motor power for the lacrimal pump; and (3) the excretory system.
This paper is presented with the hope that a detailed anatomical description of certain parts of the lacrimal apparatus will enable us to select more successful methods of treating its disorders.
A. The Eyelids.
—1. Skin and Subcutaneous Fascia: Although these are 2 distinct entities, they may be treated grossly as one layer which is very thin and somewhat elastic. The palpebral furrows divide it into 2 parts
