The document discusses various conditions that affect the conjunctiva. It begins with the anatomy of the conjunctiva, identifying its main structures. It then discusses several infectious conditions that can affect the conjunctiva like acute bacterial conjunctivitis. It also discusses trachoma, an endemic chronic infectious disease of the conjunctiva and cornea in Egypt caused by Chlamydia trachomatis. Other conditions discussed include allergic conjunctivitis, vernal keratoconjunctivitis, phlyctenular keratoconjunctivitis, degenerative changes, subconjunctival hemorrhage, and xerosis.
