Transactions . ls are also in the perivascular spaces of the perforatingvessels of,the limbus. The iris is atrophic and is adherent to thelens capsule. There is a good deal of lens matter present. Thelens and the capsule are caught slightly in the wound. Where thelens is caught it shows an increase in cellular elements; in otherparts there are degenerative changes. The ciliary body is oede-matous, its blood vessels are engorged with blood, and it showsan increase in cells. The same may be said of the ciliary pro-cesses. The choroid is the seat of an albuminous exudate, whichis mostly in the external layers and has pushed the internal layersand retina inwards, giving rise to what macroscopically lookedlike detachment. In places in the exudate there are masses ofmononuclear leucocytes. The choroidal vessels are full ofblood. The retina shows no marked changes except in the re-gion of the papilla where it is swollen and thickened and pushedaway from the head of the nerve as in choked disc (see figure).. • 3*0^^ The head of the optic nerve is most interesting in that the laminacribrosa is pushed back just as is the case in a marked glauco-matous cup, but there is no excavation in the papilla. The cupmade by the pushing back of the lamina cribrosa is filled with 312 Pusey: Acute Inflammatory Glaucoma. nerve fibers (see figure). In the center of the papilla there is aslight depression like a physiological cup. There is some in-crease in cellular elements in the nerve and the nervq^ fibers areswollen. The interstitial tissue is increased, the blood-vessels areprominent and their walls thickened. There are no holes orcaverns such as Schnabel and others have described in opticnerves of glaucomatous eyes. Briefly the clinical course of the case and the histo-pathologymay be summed up as follows. Clinically there is the typical his-tory of a rather rapidly developing inflammatory glaucoma. Iri-dectomy gave some relief, but after six months the tension was-)- I. Again the eye
