    6: RtpHnted from Vol. XII of the ' Ophthalmological Society's Transactions''] Epithelial implantation cyst of the cornea. By B. Treacher Collins. Cysts in tlie substance of the cornea, judging by tlie very few that have been recorded, would appear to be ex- ceedingly rare. Samuelsohn* gave the clinical details of the first in 1872, It occurred without any known cause, and when punctured gave exit to a clear fluid. Altf describes four eyes in which he found cysts in the paren- chyma of the cornea; in all of these there had been a perforating wound. In two there was a lining of uveal pigment, and in two the walls were perfectly smooth. In the last number of the ' Ophthalmic Hospital Ee- ports^t I recorded and pictured two cases of what I termed epithelial implantation cysts of the cornea. In one of these the eye was lost after a penetrating wound by a shot, in the other after extraction of cataract. In both these eyes I found cystic spaces in the cornea lined by laminated epithelium. They were small and only dis- covered upon microscopical examination, giving rise to no clinical symptoms. In the case which I bring before you this evening the cyst, which is situated partly in the cornea and partly in the sclerotic, produced a large pro- tuberance on the front of the globe. The patient, a boy aet. 12, came to the Moorfields Hos- pital on September 24th, 1888, having run a stick into « ' Klin. Monatsb. f. Augenheilk.,' 1872, p. 310. t 'Arch, of Ophth. and Otol.,' vol. vi, p. 317.
