CONTACT ROENTGEN THERAPY OF SUPERFICIAL MALIGNANT LESIONS ABOUT THE EYE

Radiologists frequently find malignant lesions in and about the eye difficult to treat. The protection of the lens and retinal structures presents a constant therapeutic problem. Even with the numerous protective devices which have been developed, it is frequently impossible to shield completely these structures from deleterious effects of roentgen rays and of radium radiation. In addition, the uneven facial contour about the eyes makes such lesions inaccessible and application of the usual types of apparatus difficult. Surgical treatment requires a delicate plastic procedure, which is usually kept to a minimum when more extensive surgical intervention is indicated. The development of shock-proof "contact therapy" units, both of the water and of the air-cooled type, has helped solve many of the radiologic problems associated with such lesions. These units incorporate a small mobile shock-proof tube of low voltage, short targetskin distance and minimal filtration, the rays of which emerge axially from
