HYDROPHTHALMOS OR BUPHTHALMUS CONGENITUS.
This has been applied to a congenital enlargement of the eyes from internal distension in children. The cases in lambs and foals quoted in the last article were evidently of this nature. They are charged on intraocular pressure acting on the delicate tissues of the embryo or unborn animal. There is not necessarily cupping of the optic disc so that persistent tension after birth cannot be insisted on.
Cases occurring in older animals, may be forms of secondary glaucoma though classed under hydrophthalmos by Mayer and others.
Treatment when demanded is along the same lines as in glaucoma.
