    [Reprinted from the Royal London Ophthalmia Hospital Reports, Vol. XIII, Part I.] ON THE PATHOLOGY OF INTRAOCULAR CYSTS. By E. Treacher Collins, Curator of the Museum. In a paper on cysts of the iris, published in 1867,* Mr. Hulke, after (h-awing attention to the frequency with which they are associated with penetrating wounds of the cornea, suggested, that in some instances, perhaps, the cyst may originate out of a portion of Descemet's membrane, which may have been torn away from the back of the cornea by the penetrating foreign body and carried before it into the iris. Having collected a large number of recorded cases, he showed that there are four varieties of cysts of the his :— 1. Delicate membranous cysts, with an epithelial lining and clear limpid contents. 2. Thick-wa]led cysts, with opaque thicker contents. 3. Solid cystic collections of epithelium, wens or dermoid cysts. 4. Cysts formed by deliquescence in myxomafca. Rothmund,! in 1872, in treating of the same subject, mentioned three cases in which a growth on the iris re- sulted from an eyelash being carried into the anterior chamber. He also stated that cysts might arise from portions of skin or of the epithelial coating of the eye carried in, in the same way. Monoyerj pointed out that the term cyst was inappli- cable to the solid growths on the iris, which he found were composed of concentric layers of epithelial cells. He prefers the name epithelial pearl tumour of the iris, a name originally applied by Virchow to similar growths in * Oplitli. Hosp. Rep., vol. vi, p. 12. t Klin. Monatsb. f.
