IT HAS been almost half a century (1909) since roentgenographic methods were first applied to the study of the lacrimal drainage apparatus. Since then, although many ophthalmologists have had experiences with these methods, there exist only a few isolated papers available as reference material in this field. Conspicuously deficient has been information concerning the appearance of the normal lacrimal system. Also, there is a lack of experience on the part of the clinical radiologist, and as a result the value of lacrimal x-rays has been limited.
This study had for its purposes (a) the development of a simple, standardized clinical method for the roentgen examination of the lacrimal apparatus; (b) the determination of roentgenographic criteria for the normal system; (c) the selection of a contrast medium, eminently suited for lacrimal roentgenography and hitherto unreported for this purpose, and (d) emphasis on the aid which this technique may afford the clinical
