Abstract

WHEN REDUCED to its simplest terms, repair of retinal detachment requires that the retina be brought into apposition with the pigment epithelium and choroid and fixed by surgically induced chorioretinal scar. The surgical procedure is formulated on the premise that proliferation of connective tissue occurs in the reparative phase of reaction to physical injury. For successful application of this premise, injury must be induced in the choroid and adjacent tissues at selected sites and depths without excessive destruction. Most contemporary operative techniques rely on heat generated by diathermy for induction of the desired injury, but even the most satisfactory results are not obtained without some undesirable destruction of the sclera. Despite the wide acceptance of this technique with its undesirable side-effects, there are few published experimental data on the factors which determine the intensity and spread of diathermy heat in the ocular tissues. Histopathological tissue study is a logical method
