AMONG the postoperative complications of intraocular surgery, those of late fistula formation and hypotony have received relatively little attention. We desire to emphasize a type of slowly leaking cicatrix, to describe the associated symptom complex and to present a method of therapy which we have found successful.

The creation of such a cicatrix is in some instances the aim of the surgeon, while in others the condition occurs when least desired. If such a cicatrix opens to the surface, a fistula is produced. This fistulous tract may be large or small. It may be constantly open, or it may be closed at times and open at others. The clinical appearance of the usual form, in which the fistula is large and open at all times, is well known. The
