    patient. This latter is suggested by the occurrence of the comphcation in both eyes, or in two operations on the one eye (e.g., in a preliminary iridectomy and in the subse- quent extraction operation).* The leakage commonly ceases within a week or two, but considerably longer delays have been recorded. A. Terson reported one lasting a month and a half. And the forma- tion of a broad anterior synechia ma}- prevent re-formation of the chamber after the drainage of fluid has stopped and the tension of the eye risen. It is curious that the complication seldom leads to evil consequences. Invasion of corneal wounds by pyogenic organisms is probably prevented by the surfaces becoming covered with epithelium, and by the flow of fluid from within the globe. But infections have been recorded.! Prolapse of iris may occur, in eyes other than those with sclero-corneal incision gaping under the conjunctiva. Also anterior synechia, with consequent glaucoma and possibly extensive corneal opacity (contact keratitis). And one fears lest downgrowth of corneal epithelium into the anterior chamber should give rise to glaucoma by blocking the filtration angle. Elliot I (Madras) relates a case in which the patient turned down the corneal flap with his lid on the thirteenth day, causing a free vitreous escape. A median suture was applied several days later to the bulging wound. In the large majority of cases nothing is required in the way of treatment beyond continued bandaging of the eye without pressure, till the anterior chamber refills. The merely soft eyes, with the chamber normal or nearly so, appear to require simple protection from injury by a * Harlan, Awi. of Ophih., vii (1898), 568. t See, for example, Czermak, ' Die Augeniirztlichen Operationen,' S. 940 ; Barck, Anicr.
