Standardized Echography in the Diagnosis of Lacrimal Drainage Dysfunction

Ultrasonic visualization of the effect of blinking on the lacrimal pump mechanism

“…A combination of A-mode and B-mode techniques has been used by many investigators to differentiate the components of the lacrimal apparatus [13,15,19,4,26]. However, most of these reports concentrated on the lacrimal gland and did not provide information on the function of the LS.…”

Efficacy of probing for children with congenital nasolacrimal duct obstruction: a retrospective study using fluorescein dye disappearance test and lacrimal sac echography

“…The probe was positioned over the medial canthal tendon, perpendicularly orientated to the lateral nasal wall; after that, it was anteroposteriorly swept (firstly medially and then laterally) to obtain the widest oblique longitudinal section of LS. Subsequently the probe, with its superior pointer kept toward the nose, was horizontally orientated and then vertically swept, to acquire the widest LS transverse section [39,40]. Longitudinal and transverse dimensions of LS were examined on frozen images.…”

Use of ultrasound diagnostics in lacrimal sac diseases

“…Ultrasound diagnostics can also be used [3,5,7,8,10]. It is important that most ophthalmologic ultrasound equipment is suitable in the diagnostics of the lacrimal sac diseases.…”
