Proximal canalicular imaging utilizing ultrasound biomicroscopy B: Canaliculitis

The proximal canaliculi can be imaged in patients with canaliculitis utilizing ultrasound biomicroscopy. The caliber of the proximal canalicular lumina, dilated by the disease process, can be evaluated. In addition, stones, debris and tissue fluid may be visualized within the system, without the need to inject a viscous material. This technique may prove to be of value in patients with mild or subclinical canaliculitis from the perspective of diagnosis. Outlining the extent of the disease process within the canaliculus may have some therapeutic value as well.
