Abstract
IN 1942 we recommended the use of nonperforating cyclodiathermy in treatment of various forms of intraocular hypertension. Since then, we have endeavored to improve this operation and to determine its indications and the mechanism of its hypotensive effect.1 During this period, while all scientific exchanges between the United States and Belgium were cut off, Albaugh and Dunphy2 described a similar operation. This, however, differs from ours in several points, which we shall comment on later. NONPERFORATING THERMOMETRIC CYCLODIATHERMY Diathermy Apparatus. —A diathermy electrode is applied to the eyeball at the posterior edge of the ciliary body, and the heating of the tissues (fig. 1) is effected with the high frequency current. The apparatus has two circuits: One, the diathermy circuit, generates the high frequency current and produces the heating of the tissues; the other, the thermometer circuit, provides for the measurement of the tissue temperature. It is not
