Proximal canalicular imaging utilizing ultrasound biomicroscopy A: Normal canaliculi.
The proximal canaliculi are the most difficult structures within the lacrimal drainage pathways to be imaged. Dacryocystography has been the most useful method for imaging the canaliculi, but it cannot demonstrate the canaliculi distal to an obstruction, nor can it demonstrate the walls or tissue surrounding the walls of the canaliculi. Ultrasound biomicroscopy utilizing a high-resolution subsurface imaging technique is able to image the proximal canaliculi in the cadaver model.
