RECENTLY Peters,1 in England, and Waters and Stock,2 in the United States, have presented information concerning an effective antiarsenical agent, BAL (2, 3-dimercaptopropanol), which was discovered and developed during the war years. It has been shown not only to be an effective therapeutic agent against arsenical war agents but also to be of value in the treatment of the various types of arsenical poisonings encountered in civilian practice.
It is the purpose of this review to give a brief summary of the development of BAL for ocular therapeutic use.
