[Treatment for chronic dacryocystitis by probing through naso-lacrimal duct under endoscopy].

OBJECTIVE: To determine the possibility of curing chronic dacryocystitis by probing through naso-lacrimal duct under endoscopy. METHOD: 30 adult eyes with chronic dacryocystitis were divided into two groups: 20 treated under endoscopy as endoscopy group and 10 under rhinoscope as control. RESULT: In endoscopy group, treatment in all 20 eyes successed at the first time, but in control group only in 8 of the 10 eyes successed at the first time and the other 2 needed second surgery. CONCLUSION: Treatment for chronic dacryocystitis by probing through naso-lacrimal duct under endoscopy is better.

[Alternatives to recovery of lacrimal duct patency].

Based on his many years' experience in treating patients with lacrimal duct abnormalities and on his familiarity with the latest progress of endoscopic microsurgery of dacryocystitis, the author presents a historic analysis of the development of currently available surgical treatments of dacryocystitis in Russia and foreign countries. He reviews treatments divided into the following groups: 1) operations applying an external approach to the lacrimal sac, such as Toti's-type ones; 2) those applying an intranasal approach to the lacrimal sac, such as West's-type operations; 3) intranasal endoscopic microdacryocystorhinostomies; 4) intranasal laser microdacryocystorhinostomies; 5) transcanalicular endoscopic laser microdacryocystorhinostomies; 6) operations that recanalize the lacrimal duct; 7) medical treatments of dacryocystitis. The author emphases the merits and discloses the prospects of endoscopic microsurgical treatments for impaired lacrimal duct patency and dacryocystitis.

[On classification of lacrimal duct diseases].

The new classification of diseases of the lacrimal duct is based on the anatomic localization and origin of the pathological process, its clinical pattern, type of inflammation, and main complications. Special attention is paid to the terms.

[A new method of lacrymal derivation in the canalicular obstruction (author's transl)].

The authors believe that in their experience the best method of lacrymal derivation in the canalicular obstruction is the Jone's technique. However, the post operatoire complications are numerous in this method and therefore they are looking for a new procedure of lacorhinostomy: - the type of tube is a silicone tube which has the great advantage of not irritating the tissues; - the silicone tube is introduced into the lacrymal duct. After having used this technique for four years the authors are convinced that this is the best method.

Lacrimal duct injuries revisited: a retrospective review of six patients.

This is a retrospective review of 6 patients treated for lacrimal duct injuries between December 1994 and October 1997. Four patients had inferior canalicular lacerations, one had a superior laceration, and one had a combined inferior and superior laceration. Associated injuries included facial fractures (1 patient), multiple facial lacerations (2 patients), and avulsion of the medial canthus (1 patient). All patients were repaired with Crawford tubes using a semicircular technique. The mean time of lacrimal intubation was 4.2 months (range, 3.6-4.5 months). One tube fell out at an undetermined time during the follow-up period. Visible anatomic restoration was considered excellent in all patients. There were no instances of persistent epiphora or other complications. Although there are several techniques available for treating lacrimal duct injuries in the course of dealing with general facial trauma, the semicircular technique using a Crawford intubation system yielded consistently reliable results with minimal or no complications.

Does lacrimal duct occlusion decrease intraocular pressure in patients refractory to medical treatment for glaucoma? A randomized, sham-controlled, crossover trial.

We temporarily occluded lacrimal ducts with dissolvable collagen inserts in a randomized, double masked, sham-controlled crossover trial to test whether longer ocular contact of eye drops lowers intraocular pressure in patients with refractory glaucoma. Patients were randomized to the sequence temporary lacrimal duct occlusion----21 day washout----sham occlusion (6 patients), or the reverse order (5 patients); all maintained their usual medication. Compliance was greater than 90% for every patient as assessed by medication diaries kept by each patient's medication partner. There was no treatment effect (bivariate Wilcoxon chi 2 = 0.10, p = 0.95) or treatment-period interaction (chi 2 = 2.87, p = 0.24). However, whichever treatment was received first significantly lowered intraocular pressure (left eye first period X:[ipr50] = 3.0: [-6.0, -1.0] mmHg, right eye = -3.0:[-6.0, -1.0] mmHg, bivariate response chi 2 = 5.92, p = 0.05). Although lacrimal duct occlusion appears to have no clinical benefit, more careful supervision of eye drop administration may be efficacious for treating some patients with medically refractory glaucoma.

Radical resection for naso-lacrimal duct tumour.

Naso-lacrimal duct tumours are uncommon and present with epiphora and swelling. Since the naso-lacrimal duct is embedded in bone for the majority of its anatomical length, the late presentation of proptosis is due to orbital extension of the tumour. Radical surgical treatment is necessary to establish clear margins and facilitate reconstruction.

What happens to tears inside the efferent lacrimal passage? An animal experimental study.

BACKGROUND: To determine whether absorption of protein components of the tear fluid occurs in normal efferent tear ducts, an animal experiment was carried out. METHODS: Iodinated albumin was dropped into eyes of female rats. After 10, 20 or 60 min the rats were killed, blood collected and the heads embedded for histological examination. Serum was obtained from the clotted blood and the radioactivity in a protein sediment and the combined supernatants counted. In a second approach, serum was fractionated by molecular mass and radioactivity in the fractions measured. Furthermore, autoradiographs of rat head sections were performed. RESULTS: Uptake of radioactivity into the serum was low, but increased with time. After 60 min maximal incorporation of the applied radioactivity into the blood was 0.13%; most (70-80%) of the incorporated radioactivity was not protein bound. Gel chromatographic separation according to molecular mass yielded fractionated peaks of radioactivity corresponding to albumin with maximal 4.8 Bq/ml serum, iodinated tyrosine (5.5 Bq/ml), and free iodine (237 Bq/ml; each after 60 min). Histologically the rat efferent lacrimal tear ducts showed a multilayered lining epithelium with integrated goblet cells in a characteristic arrangement of several cells. In autoradiographs of rat head sections no transport of radioactivity could be visualized. CONCLUSION: In rats only traces of iodinated albumin are incorporated from the efferent lacrimal tear ducts into the blood. A higher proportion of the radioactivity is taken up as the proteolytic degradation product of bovine serum albumin to free amino acids, and 96% of the radioactivity incorporated was free iodine, probably as a contaminant of the iodinated preparation.

[Radionuclide imaging of lacrimal duct in health and disease].

Dacryoscintigraphy is a perspective method for examination of the lacrimal system function. It has many advantages over other methods (functional tests, roentgenography, and computer-aided tomography) and notably improves the diagnostic potentialities of examination of the lacrimal function. The technique and results of the method are discussed.
