Chemiluminescent evaluation of the human lacrimal outflow system.

A chemiluminescent material, Cyalume, has been used to demonstrate the structure and outflow patency of the human lacrimal drainage system. In this paper the details of this method are outlined and some of the possible benefits and limitations are discussed. Work is in progress to improve the techniques and to evaluate the toxicity of the chemiluminescent material in animals. It is hoped that these studies will lead to the development of a simple and rapid office procedure for assessing the structure and patency of the lacrimal tracts and simultaneously evaluating any obstruction.

An alternative method of closed silicone intubation of the lacrimal system.

An alternative method of closed lacrimal intubation is described, the basis of which is to place the end of a piece of silicone tubing over the end of a small-diameter metal introducer, stretch the silicone tubing back along the introducer, and then pass the introducer together with the tubing through the lacrimal system into the nasal cavity. The tubing is visualized in the inferior meatus, from where it is retrieved, and then the introducer is withdrawn. The other end of the tubing is passed in a similar fashion. The technique is easily mastered, inexpensive, and less traumatic than other described techniques.

A pre-swedged silicone tube to simplify pigtail canaliculoplasty.

Silicone intubation of the canalicular system is indicated for stenting following canalicular trauma or surgery, or to dilate chronic stenosis of the punctum or canaliculus. Monocanalicular systems are available, but bicanalicular intubation is generally more stable and is particularly suitable for disease involving both the upper and the lower punctae or canaliculae. Bicanalicular intubation can be accomplished by intubating the entire lacrimal outflow system into the nose, or more simply by intubating the canalicular system alone using a pigtail probe. To use the pigtail probe to pass and fixate a segment of silicone tubing, the silicone tube is passed using a monofilament suture. A pre-swedged silicone tube segment on a monofilament suture has been designed to simplify the process of pigtail probe intubation of the canalicular system.

[Role of nasolacrimal intubation in the treatment of lacrimation caused by congenital lacrimal duct obstruction in infants].

We report a study of a series of 83 cases of congenital nasolacrimal duct obstruction treated with monocanaliculonasal or bicanaliculonasal silicone intubation. Efficacy, complications, as well as the duration of the placement of the probes were studied. The analysis of the various factors of this series (age of the infants at the time of intubation, duration and type of intubation, complications) demonstrated the superiority of short-term monocanaliculonasal intubation (about four weeks) compared to longer intubation.

Complete obstruction of the nasolacrimal system. Part II. Treatment with expandable metallic stents.

To evaluate the clinical usefulness of expandable metallic stents for maintenance of the dilated nasolacrimal sac and duct, double stents were implanted under fluoroscopic guidance in seven patients with severe epiphora after failed balloon dacryocystoplasty. Stents were constructed of 0.25-mm stainless steel wire in a cylindrical zigzag configuration of 10 bends. A single stent was 4 mm in diameter when fully expanded and 10 mm long. The stent was placed accurately in all but one patient, in whom a second stent was placed accurately after removal of the dislodged stent with a hemostat under endoscopic guidance. After stent placement, all patients demonstrated complete resolution of epiphora. During follow-up of 4-20 weeks, complete blockage of the stent occurred in one patient. This was treated with intrastent balloon dacryocystoplasty. No stents migrated. Although the long-term validity of this treatment has not been proved, expandable metallic stents seem to be of value in the treatment of complete obstruction of the lacrimal sac and nasolacrimal duct.

[Connatal dacryostenoses. Clinical picture and treatment].

Connatal dacryostenosis involves obstructions of the lacrimal passages in all parts of the system as well as supernumerary structures like the connatal fistula of the lacrimal sac. Usually intervention in infants with aplasia of the puncta is not necessary. When the lacrimal passages are involved in coloboma of the lids or facial cleft, reconstruction depends on the usable tissue of the lacrimal system. Treatment of connatal mucocele consists of digital expression of the pseudo-tumor. In cases of connatal dacryostenosis due to Hasner's membrane in infants, massage of the lacrimal sac as well as application of antibiotic eye drops and detumescent nose drops is indicated. After 5 or 6 months high-pressure irrigation with the hollow probe of Bangerter is necessary. Important is the postoperative treatment with detumescent and antibiotic eye drops as well as with detumescent nose drops for 1-2 weeks. In acute inflammation, treatment of the inflammation is the first goal of therapy, which may be combined with incision of the abscess. This can be performed by transcutaneous incision as well as by endonasal intervention in cooperation with a rhinologist.
