Abstract

The conjunctiva is a thin and moist mucous membrane. It covers the anterior part of the eye, saves the cornea, reaches peripherally into the upper and lower fornices, and then reflects to outline the inner surface of the eyelids. This sac remains incomplete at the bottom as the conjunctival epithelium transitions into the corneal epithelium, leaving the cornea devoid of conjunctival tissue unless pathology supervenes. At the top of the conjunctival sac, the interpalpebral fissure opens into the sac and the anterior ocular surface. The conjunctiva serves many purposes including some of great importance to ocular function. First, it secretes mucous material onto the ocular surface and contributes to the tear film. Second, it provides an anatomical and cellular barrier to foreign particles and bacteria.
