ENCANTIIIS. Tun Encanthis is a tumour arising from or at least involv ing the caruncula lacrymalis, it is of a pale red colour, and irregular on its surface; as it increases it draws into its sub stance the semilunar fold of the conjunctiva and stretches its root along both eyelids. When this tumour is of a darker 61 OF THE PTERYGION. THE Pterygion is a pale red film, which stretches generally from the inner angle of the eyelids, across the cornea. It is one of the pure consequences of continued inflammation. When this web covers the whole eye it is called names. But hue and hard, and has lancing pains in it, and still more when becoming more active and vascular, it bleeds easily or gilt-1.35M mom the terms film and web deceive us, for this is not a new mem- brane formed on the surface of the eye, but only a congestion ulcerates, it is becoming cancerous. i Even before the tumour shows this cancerous character there occur good reasons for cutting it. oil". When it becomes rooted in the eyelids, and the cancerous disposition has spread, nothing but the extirpation of the whole eye will avail, if i t 3 in the cellular membrane, under the conjunctiva, which, as it were, loosens it from the sclerotica, at the same time that its vessels are increased in number, and become tortuous. This diseased state of the conjunctiva encroaches in a conical form on the lucid cornea: it is there too of the same nature; the even that is effectual.

THE patient being seated with a cloth under his chin, the assistant stands behind him and supports his head, having in one hand a sponge full of tepid water, which from time to time, in the progress of the operation, he pours into the eye, as it becomes obscured by blood. The assistant opens wide the eyelids. 2. The surgeon now with very fine forceps raises the apex of the pterygion which is 011 the cornea; he then pushes the knife, used for the extraction of the cataract, under the fold of the membrane which he has raised; he carries the knife for- ward until the edge shall have cut itself out, and have separated the very apex of the membrane from the cornea. |
