Unilateral Membranous Conjunctivitis, with Complete Cast.

The, condition' may be regarded as a moinimal form of maldevelopment of the optic cup; grosser forms are known, which result in the formation of the various degrees of congenital cyst of the eye. The other form of congenital ectropion uveae is that in which the two ectodermal pigment layers -remain in contact but come to lie further round on the anterior surface of the iris than usual. This is ascribed to a simple overgrowth or to dragging of the layers by inflammatoxy tissue; it is not associated with persistence of the marginal sinus. Very small rape seed 6odie5 are sometimes seen around the pigment border of the iris. These occasionally become loose and float in the anterior chamber as small, rounded pigmented bodies. That they really are detached corpora nigra is shown by a case of Dymschitz, in which from one half of the iris border they had become detached as a beaded string lying in -the anterior chamber, while those of the other half were still in place on the iris. No treatment has been given to this patient. Summary.-A description is given of a rare case of iris flocculus with anterior synechia, and a note on the development of flocculi.
