(c) Cicatricial trachomaresents the latecharacterized byof gray-white scar lines. Theyoften intersect remains of oldgranulations. There is not muchsecretion in this stage, unless an exacerbation occurs, and often theconjunctiva is very dry. During the course of trachoma certain complications develop, themost conspicuous being (a) Acute exacerbations, or superadded in-fections, to which reference has been made. When they are con-spicuous the irritative phenomena are intense, with scalding tears,great dread of light, corneal involvement, and purulent discharge;. rep-stage, and isthe formation.

DISEASES OF THE CONJUNCTIVA. 45 (b) Pannus] which is a form of vascular, keratitis, and while therough upper lid is a predisposing factor, the condition really repre-sents a form of direct infection. Usually the condition is first mani-fest in the upper half of the cornea, and vessels proceed inward fromthe corneal loops, and at first lie between the epithelium and Bow-mans membrane. In severe cases this tissue may break down andthe deeper corneal layers may be involved, (c) Ulcers of the cornea,which may be deep and sloughing, may perforate the cornea, andmay leave dense scars and give rise to staphyloma, or which may beshallow and be centrally placed, with a turbid base, at or near theapex of the pannus. (d) Trichiasis, entropion, and ectropion, whichhave been described (page 33). (e) Xerosis of the conjunctiva, themembrane undergoing, as the result of induration, a form of dryingup. L
