Ritleng Probe ProcedureRitleng Probe Procedure

The Ritleng Probe is backed out of the lacrimal duct and separated from the polypropylene thread-guide at its thinner section (the light blue portion of the thread) by sliding it out from the open slit that lines the entire length of the probe.

The thinner section of the thread-guide is shown separating from the probe by sliding out from the open slit.

Following dilation and preliminary probing of the lacrimal ducts, the Ritleng Probe is introduced into the canaliculus and nasolacrimal duct until contact is made with the nasal fossa floor.

The probe is pulled back slightly (1cm) to facilitate the introduction of the prolene thread-guide into the nasal cavity.

The probe is oriented with its slit side facing anteriorly and pushed backwards so that the interior end of the probe is facing anterior, thus directing the prolene towards the front of the nasal cavity.

The prolene is threaded through the probe to obtain a large loop which spreads out in the nasal cavity making it easy to locate.

Retrieval of the blue prolene is easy when it appears in the anterior portion of the nose.

The prolene is retrieved under nasal illumination and visual control (nasal endoscope) with endonasal forceps with the Ritleng Hook.


If the prolene thread-guide is not easily located in the anterior portion of the nose, or if it takes a posterior direction, the following technique is used for retrieval:

The probe is introduced until contact is made with the nasal fossa floor.

Metal-to-metal contact is made using the Ritleng Hook high up in the inferior meatus near the exit of the nasolacrimal duct.


The probe is then rotated 180° while keeping the metal-to-metal contact with the hook thus orienting its inferior opening towards the back.

The hook should be above the probe’s opening and the prolene. This will enable the hook to catch the prolene loop when removing from the nose.


The probe is slowly back out of the inferior meatus and as soon as the metal-to-metal contact between the probe and the hook is lost, the hook catches the prolene loop and is carefully removed from the nose.

The probe is removed from the canaliculus and detached from the stent by sliding the thinner light blue portion of the prolene out through the probe’s slit.

The prolene thread-guide is pulled out the nose along with the attached silicone tubing.

This same technique is used to intubate the second canaliculus in the case of a bicanalicular intubation.

In the case of a monocanalicular intubation, the punctal plug at the other end of the silicone tubing is seated in the puctum using a punctal plug dilator and inserter.
