Follicular conjunctivitis frcqviently causes the formation of various sizednodules (hypertrophied follicles) round bodies about the size of a milletseed, deep red in color, and may sometimes produce a tumor which isvisible in the internal canthus of the eye. When the memlirane ispicked up and examined by means of a pair of forceps, and enlargementof the meml)rane is indicated by a pink red tumor in the internal cornerof the eye, which moves over the eyes on slight pressure on the eyeball; INFLAMMATION OF THE CONJUNCTIVA 401 this tumor not only originates from follicular conjunctivitis, but fromtraumatic causes and neoformations such as adenomas of Harders gland,lipomas or papillomas.
