SOME POSSIBLE advantage in convenience over the well-known "iodine-scrub" treatment for dendritic or herpetic keratitis is offered by a simple modification which I have made and have utilized in treating approximately 40 patients with this type of keratitis during the past eight years. The initial impression has been obtained that the modified treatment is as good as the old, and in some cases possibly better, but the data are as yet insufficient for a significant comparison of effectiveness. The modification consists in substituting for the usual swabbing with tincture of iodine an exposure of the virus-infected cornea to a controlled dose of iodine vapor from a tube containing iodine crystals, with no rubbing or scrubbing or subsequent "neutralization." The element of convenience lies in the fact that the application of iodine vapor to the cornea is easily made in a few minutes with the patient in a sitting position.
