Text-book of ophthalmology . theeyes. There is a second scar at the outer end of the lower margin of the orbit. This, indeed, is con-cealed by the margin of the lid, but by palpation through the lid it can be made out that there isan irregular notching of the otherwise sharp and smooth orbital margin. At the same spot, the borderof the lid is attached to the bone and in such a way that the entire lid is drawn outward and down-ward and everted, particularly in its outer half, so that here the conjunctiva of the tarsus, being ex-posed to the air, is particularly swollen and reddened, and consequently appears dark in the lower lid, being fastened down, cannot be raised when the attempt is made to close the eyes. Hence,even in sleep the lower part of the cornea between the two lids remains uncovered. This part of thecornea presents an oblong ulcer with yellowish-white border and an excavated and hence somewhatdarker center. Above and below, an areolate gray opacity adjoins the yellow margin of the h^xus^ re_, fcagflSfeaaj&ttfe&afeMg Fig. 104.—Keratitis e section through the lower part of the cornea. The epithelium, e, has been retained onlyin the neighborhood of the limbus, but over the dried portion of the cornea, a, it has been portion of the cornea is necrotic, and no longer displays any stained cell-nuclei. Under it thereis an infiltration of the cornea with pus corpuscles. This infiltration increases rapidly toward thelower margin of the cornea, here, at b, has already caused by liquefaction of the tissue a small loss ofsubstance, and would later lead to elimination of the entire mass, a. Bellow b, a less marked infiltra-tion extends to the lower margin of the cornea. This corresponds to the gray areola which adjoinsthe yellow border (Fig. 103). There is furthermore an infiltration of the cornea with pus cells on the ftosterior surface, h h. This at present is inconsiderable, but in the subsequent course w
