A major phase of contemporary surgical treatment of retinal detachment is the application of diathermy through the sclera, or under scleral flaps, to produce focal areas of heat injury at selected sites in the choroid. It is hoped that the proliferative reaction induced by the injury will result in firm adhesions between the retina and pigmented epithelium. The procedure is an exacting one which too often fails because the reaction is misplaced, inadequate, or excessive. In present techniques, determination of penetration of the surgical probe and the proper intensity and duration of application of the current unfortunately are largely dependent upon the technical skill, clinical judgment, and experience of the surgeon. More controllable methods of inducing heat injury are badly needed. At this institution, a diversified approach has been made to the problem. On one hand, we have sought a better understanding of the reaction of the eye to heat
