Serial studies of pulmonary function in this disease are few (4) and the interval between observations short. Yet, studies of clinical and radiologic course cannot be extrapolated to supply this knowledge; patients whose X ray has cleared may have a low diffusing capacity (5). There is need, therefore, of additional studies on the course of pulmonary function in sarcoidosis in relation to clinical and radiological data. The present paper reports serial observations of 18 such patients over...
