Abnormalities of the palpebral aperture.

Abstract

The socket surfaces, conjunctival fornices and palpebral aperture are intimately related. Any socket or fornix abnormality will affect the contour and size of the palpebral aperture. Conversely, a cicatricial lid deformity will alter the depth and contour of the conjunctival fornix. Any surgical correction of a lid malposition must calculate the resultant effect on the socket.
