During the past two decades reports in the United States and Europe have been unanimous that the best treatment of angiomatosis retinae is diathermy coagulation of the classic "bee's nest" lesion and the vessels extending to it. If the angiomatous lesion is early in development, localized, and located peripherally, the prognosis for useful vision is good, though there is always the possibility of cerebellar involvement. In 1943 Cordes and Dickson reported favorable results with x-ray irradiation, but during the intervening years these authors have come to prefer diathermy coagulation. In 1943 Guyton used coagulation diathermy upon both eyes of a 13-year-old girl. The early lesion eye retained normal vision, and the late lesion eye was retained, though it did not regain vision. Eight years later the process extended into the cerebellum and the patient died.
In 1948 Lewis reported two patients whom he had treated with diathermy and had followed
