    ON A NEW OPEEATION FOR REMOVAL OF POSTERIOR ADHESION OF THE IRIS. When, in iritis, a single point of adhesion between the pupil- ary margin of the iris and the lens has been formed, there is great danger that the eye will remain ever after a damaged organ. Should the use of atropine (as is very usual) fail to destroy, while yet soft, this point of adhesion, the disease tends to go on from bad to worse, for the fixed part acts as a continual irritant, causes more or less severe relapses of the iritis, and leads to the increase of breadth of the adhesion, and to atrophic changes in the iris itself. Hence it happens that the usual result of such cases, when left to themselves, is that, finally, the pupil becomes totally adherent to the lens, the anterior capsule in and near the pupil becomes covered with the products of inflammation, and this capsulitis, interfering with the nutrition of the lens, leads to the forma- tion of cataract, while the atrophic iris is bulged out at its periphery by the fluid in the posterior chamber, and forms a convex ring round the occluded pupil. The deeper structures of the eye usually suffer at the same time. The treatment of adhesion between the iris and lens, posterior synechia, as it is called, is one of the least satisfactory parts of the ophthalmic practice. In iritis and corneitis, where these are so apt to be formed, the use of atropine
