THE EYE radiation for the purpose of treatment or diagnosis. Among these are the grenz rays, which have been used extensively for the past fifteen years. They are soft rays of 1 to 4 angstrom units, intermediate between the ultraviolet and the usual roentgen rays,1 and have some biologic properties in common with both of these, more familiar, forms of radiant energy, but do not penetrate very deeply into the tissues of the eye.2
Grenz rays have been found of value in the treatment of superficial ophthalmic conditions, such as corneal ulcer or episcleritis, and are considered to be safer than ordinary roentgen rays. The clinical application of this form of radiation has been extensively reviewed.3 Krasso4 reported histologic changes in the cornea caused by heavy single irradiations of the rabbit eye. Gallardo, Pfeiffer and Thompson5 found that infections produced by intracorneal injections of staphylococci healed
