LACRIMAL ULTRASONOGRAPHY

Lacrimal ultrasonography (echography) evaluates lesions in that draina ge system in a painless, noninvasive way in the office. The technique complements other imaging methods and can be correlated with histologi cal results. The authors survey the principles and technique and descr ibe the normal ultrasound, indications, applications, and limitations. Lacrimal ultrasound, whose potential has just lately been recognized, only reveals gross anatomic abnormalities and cannot evaluate the fun ctional integrity of the lacrimal excretory system.
