![3. [Reprinted from The Philadelphia Monthly Medical Journal April, 1859.] ’ HYDROPHTHALMOS—A BIBLIOGRAPHIC CLINICAL AND PATHOLOGIC STUDY. By WALTER L. PYLE, M.D., of Philadelphia. Assistant Surgeon to Wills Eye Hospital. Hydrophthalmos is a more or less uniform in- crease of all the diameters of the infantile eyeball, due to the expansion and consequent thinning of the elastic sclera under increased intraocular pressure It occurs at birth or in early infancy, but cases of later development have been reported. It may be unilateral or bilateral. Considerable confusion has arisen from the multi- plicity of names used to denote this condition. We find in literature all of the following titles : Hydroph- thalmos, hydrophthalmos congenitus, hydrops oculi, dropsy of the eye, buphthalmos, “ox-eye,” megal- ophthalmos, megalocornea, keratoglobus, cornea glo- bosa, globose cornea, glaucoma congenitum, congenital glaucoma, infantile glaucoma and infantile secondary glaucoma. With such a variety of titles, the difficulties of preparing a bibliography and collecting the various expressions of opinion relative to this subject maybe readily understood. Unfortunately no author has called attention to this chaotic state of the nomencla- ture ; it is only by securing the best descriptive name and uniformly adhering to it that universal biblio- graphic research may be systematically pursued. Hydrophthalmos is undoubtedly the best name to use. It describes a general underlying condition without refuting any theory of causation or misinter- preting any local expression of the disease. Hydroph- thalmos congenitus and hydrops oculi are not of such common usage and consist of two words.](https://iiif.wellcomecollection.org/image/b22369302_0001.jp2/full/800%2C/0/default.jpg)
