In recent years much interest has centered on the subject of intermittent exotropia.* This has been generally considered to be on the basis of divergence excess with or without a superimposed convergence insufficiency. However, there is still some obscurity about certain aspects of this disease. This was well demonstrated at the Strabismus Symposium held in New Orleans in February, 1955, where this proved to be one of the more controversial subjects. To obtain additional information, a statistical survey was made of all cases of intermittent exotropia operated on at the University of Illinois Research and Educational Hospitals and the Illinois Eye and Ear Infirmary during the past six years.
For purposes of this study, only those patients who had an intermittent exotropia for distance were included. Thus cases of pure convergence insufficiency were eliminated. Prism cover measurements were not very helpful in the diagnostic selection of these cases because of
