IN 1936 Vogt first reported his experiences with cyclodiathermy puncture in the treatment of severe and intractable glaucoma. Later he further elaborated on three and a half years' experience with this operation, in which time the complications mentioned in his first communication were reduced to a minimum. During the past seven years, my associates and I have had opportunity to try out the method, and we believe it has a definite place in the surgical treatment of the disease, especially in cases of severe glaucoma, complicated by a very shallow anterior chamber, in which a previous operation has been done.
