Excerpt from book: KEEAT1TJS DISCIFOKMIS. W. Zextmayeh, M.D. PHILADELPHIA, PA. Illustrated.] The pathology and symptomatology of tliis rather unusual form of kcratitis has been so recently presented by Dr. de Schweinitz that it would render it trite to again refer to it. The question of diagnosis is, however, worthy of consideration. The designation given the affection by Fuchs is unfortunate in one respect, that it emphasizes its form at the expense of the more essential element of a single focus of infection with an advancing, saturated annular band marking its spread from this point; this resulting in a permanent opacity, which, if its characteristics be borne in mind, should serve to differentiate it from opacities the sequel of other types of keratitis resembling it, however, in form. For the positive diagnosis of this condition the process should have been followed from its incipiency through the inflammatory stages to the formation of the cicatrix. That some difficulty should be experienced in diagnosing it from ulcus serpens follows from the fact that it differs from it only in the intensity of the process. I have had in recent years two cases which, in their active stage, bore a superficial and in the resulting opacity a very close resemblance to keratitis disciformis. The first was one of pustule of the cornea in variola in which the process resembled an abscess, but was not so rapidly destructive as is usually the case, but did finally involve about three-fourths of the central area of the cornea and caused a prolapse of Dcscemet's membrane. The eye was for many months irritable, but finally became quiescent, so that to-day, about three years since the attack, there is a central, somewhat oval opacity involving the entire thickness of the cornea which has some of the charac...
