Infra-roentgen rays have been used in the treatment of diseases of the anterior portions of the eyeball and conjunctiva by Krasso,1 Monyukova and Serebryaniy,2 Mylius,3 Rosamoely,4 Baltin and Serebryaniy5 and others. Krasso, in a number of articles reported beneficial results in various ocular diseases with this therapy, for example herpetic corneal disease, superficial punctate keratitis, dendritic keratitis, filamentous keratitis, superficial infiltrations and ulcers and episcleritis. On the other hand, no success was observed by this author (or by Gnad6) in parenchymatous keratitis. They used doses of from 70 to 150 roentgens with one to five exposures and half value layers of 0.020 and 0.025 mm. of aluminum but pointed out that rays of the former quality produced better results.
Recently Pfeiffer7 reported on a sufficiently large material. He had treated 302 patients with a total of 1,200 exposures during the preceding five years.
