GLAUCOMA AND ITS TREATMENT. Ophth. Cong. Heidelbei g} 1888. Priestley-Smith's views as to the pathology of glaucoma have appeared so recently in the medical journals that it will be sufficient to briefly summarise them. He defines glaucoma as an excess ofpressure within the eye, together with the causes and consequences of that excess; the pressure of the intra-ocular fluids is determined by three conditions :? (a) The condition of the secretiug organs, chiefly represented by the ciliary processes. (Z?) The condition of the outlets ; practically the angle between the iris and the cornea, whether wide or closed by advance of the iris base, (c) The conditiou of the fluids. When albuminous he shows by experiment that excretion is retarded. Inter.

The order of events producing an attack is, of ciliary processes in an eye with a narrow circumlental space; this has the effect of pressing the iris base against the cornea, and so preventing exit of waste fluids from the eye; more congestion is the necessary result, and later on, the fluids which are secreted become albnmiuous, and thus increase the difficulty of their escape. The paper was very fully illustrated, and the clearness of the demonstration was much admired and remarked upon. Snellen recognises two distinct clinical types of glaucoma, the one being associated with a shallow anterior chamber (Gr. posterius) and due to relative overfulness of the vitreous chamber; the other (Gr. anterius) where the anterior chamber is deep. The former (usual form) he treats by eserine and sclerotomy combined, the operation being performed by the thrust of an iridectomy knife, and not, as most do it, by means of a Graefe cataract knife. Glaucoma anterius, as seen in cases of keratitis diffusa, iritis serosa, is not benefited by myotics and is treated by atropine.?Medical Chronicle, July 1889, p. 323.
