The clinical value of dacryoscintigraphy in the selection of surgical approach for patients with functional lacrimal duct obstruction.

PURPOSE: Dacryoscintigraphy is widely known to be an effective modality in diagnosing abnormalities of the lacrimal system that cause epiphora (pathological overflow of tear). However, dacryoscintigraphy rarely serves beyond the simple diagnostic use for lacrimal duct obstruction. In our study, dacryoscintigraphy results of patients with functional lacrimal duct obstruction are newly classified into three types, the effects and prognoses of silicone tube intubation are noted according to each type, and the role of dacryoscintigraphy in determining appropriate surgical approaches is evaluated. METHODS: Subjects were 36 eyes of 29 patients complaining of epiphora who had increased tear meniscus, but showed no sign of obstruction on duct syringing. Impression of functional lacrimal duct obstruction was made through dacryoscintigraphy, and silicone tubes were inserted. RESULTS: Patients were classified according to the results of dacryoscintigraphy; those with delayed secretion in the distal nasolacrimal duct were typed as class I; those with delays in the proximal nasolacrimal duct class II; and delayed secretion from the pre-lacrimal sac to the lacrimal sac as class III. All patients had silicone tube intubations together with selective punctoplasty. Symptomatic improvement was observed in all 6 cases of distal nasolacrimal duct obstruction (100%), 14 of 18 proximal obstruction cases (77.8%), and 8 of 12 pre-lacrimal obstructions (66.7%). CONCLUSIONS: Functional lacrimal duct obstruction is easily diagnosed with dacryoscintigraphy. Furthermore, its may be classified by types of obstruction to predict post-operative results of silicone tube insertion. Cases suspicious of pre-lacrimal sac obstructions in particular may achieve better operative results with adjuvant treatments in addition to silicone tube insertion.

Dilatation and stenting for naso-lacrimal duct obstruction: a pilot project.

PURPOSE: Obstruction of the naso-lacrimal duct has traditionally been treated by dacryocystorhinostomy. This pilot project aimed to evaluate the use of stents as an alternative approach to the treatment of naso-lacrimal duct obstruction. METHODS: Six patients with naso-lacrimal duct obstruction underwent a pre-procedural dacryocystogram to confirm the site of obstruction. Under local anaesthesia, they subsequently underwent dilatation of the naso-lacrimal duct using a guide wire and a plastic dilator aided by fluoroscopy and digital subtraction imaging. The stent was then placed with its head in the lacrimal sac and tail protruding out of the naso-lacrimal duct into the inferior meatus. Dacryocystography was repeated to confirm patency. Patients were followed up for a minimum of 12 months. RESULTS: The procedure was successfully completed in four of the six patients. In one patient, we failed to negotiate the guide wire and in one, a false passage was created. All four successful cases were rendered asymptomatic and their lacrimal passages remained patent at 12 months. CONCLUSION: Naso-lacrimal duct dilatation and stenting is a viable alternative to conventional dacryocystorhinostomy in the treatment of naso-lacrimal duct obstruction and merits a larger trial.

[Lacrimal duct obstruction treated with lacrimonasal stent].

OBJECTIVE: To analyze a series of patients with lacrimal duct obstruction treated with polyurethane stents. MATERIAL AND METHODS: We studied 125 cases of lacrimal duct obstruction corresponding to 115 patients, of whom 30 were males (26.08%) and 85 females (73.91%). The obstruction involved the right side in 51 cases (40.8%) and the left side in 74 (59.2%). Mean age was 65 +/- 14.64 years. Symptoms included chronic epiphora in 65 patients (52%), acute lacrimal sac inflammation in 33 (26.4%), mucocele in 6 (4.8%) and recurrent conjunctivitis in 4 (3.2%). Seventeen patients came to us diagnosed with lacrimal duct obstruction. Time of follow up was one year. RESULTS: Stents were successfully implanted in 120 cases (96%). Surgical complications included pain in 5.83%, eyelid inflammation in 5%, nasal bleeding in 0.83% and false duct in 0.83%. Functional success was achieved in 82 patients (68.3%), and surgical failure occurred in 38 patients (31.7%). Mean time of stent failure was 178 days. In these cases, inner granulation tissue was found in 63.15% of the cases and mucoid material in 36.85%. The most common postoperative complication was mucocele formation, which ocurred in 7.5% of the patients. CONCLUSIONS: In our experience, polyurethane stent implantation is a good alternative for treating nasolacrimal obstruction, but not as effective as endonasal or external dacryocystorhinostomy.

[Clinical diagnosis of lacrimal duct obstruction by digital subtraction dacryocystography].

OBJECTIVE: To illustrate the value of digital subtraction dacryocystography in the diagnosis of lacrimal duct obstruction. METHODS: Eighty-two normal eyes and 56 eyes with epiphora were investigated with digital subtraction dacryocystography and the dacryocystogram were studied. RESULTS: Lacrimal drainage system imaging by the digital subtraction dacryocystography provided reliable and accurate demonstration of lacrimal duct obstruction. CONCLUSION: Digital subtraction dacryocystography is a rapid, effective and noninvasive imaging technique, and it is helpful in the diagnosis, treatment and study of lacrimal duct obstruction.

Bacteriology of lacrimal duct obstruction in adults.

AIMS: To determine the current bacteriology of lacrimal duct obstruction (LDO) and to relate the bacteriological findings to the type of symptoms. METHODS: 127 samples were obtained from the lacrimal sac in 118 consecutive adult patients with LDO, including nine bilateral cases. RESULTS: Altogether, 156 isolates were recovered from the 127 samples cultured. Cultures were positive from 84% of the samples. Gram positive bacteria were isolated in 79 (62%) samples. The most frequently cultured bacterial species was Staphylococcus epidermidis, representing 27% of the isolates. Gram negative bacteria were recovered from 26 (20%) samples, and these bacteria were statistically significantly more common in cases with copious discharge than in cases with minor discharge (p = 0.000). Cases with simple stenosis of the lacrimal duct (SSLD) showed significantly less Streptococcus sp (p = 0.004) and Gram negative organisms (p = 0.004) than those with chronic dacryocystitis. CONCLUSION: The bacteriology of SSLD resembles that of normal conjunctival flora. Chronic dacryocystitis in adults is associated with an increased proportion of Gram negative bacteria which may be a reservoir for postoperative intraocular infection. They should also be taken into account in selecting antimicrobial prophylaxis in lacrimal drainage surgery.

[Dacryocystorhinostomy together with temporary intubation of lacrimal canaliculi as a method of treatment of lacrimal duct obstruction].

The purpose of the study was to present the results of treatment of lacrimal ducts obstruction. The authors describe the advantages of temporary intubation of lacrimal canaliculus with simultaneous dacryocystorhinostomy. Additionally, they prove the harmfulness for probing the lacrimal ducts in adults and describe reasons of unsuccessful operations of dacryocystorhinostomy. The findings have been based on 44 operations within a four-year period.

[Lacrimal duct probing in young children with a congenital lacrimal duct obstruction at the Utrecht University Medical Center: generally an effective treatment].

OBJECTIVE: To assess the results of lacrimal duct probing in young children with epiphora, due to a congenital nasolacrimal duct obstruction. DESIGN: Retrospective, descriptive. METHOD: Data were collected from medical dossiers on the results of lacrimal duct probing in children (0-48 months) with epiphora that was done in the period from January 1, 1997 to December 31, 2001 at the University Medical Centre in Utrecht, the Netherlands. The percentage of eyes that showed complete resolution of symptoms three months after the final probing was calculated. RESULTS: Of the 89 children who had undergone lacrimal duct probing, seven were excluded and in three children (six eyes) the data could not be retrieved. In 96 of the remaining 116 eyes (83%), the symptoms disappeared: this included 96% of the age group 0-12 months (n = 25), 85% of the 13-24 months-olds (n = 55), 77% of the 25-36 months-olds (n = 22) and 57% of the 37-48 months-olds (n = 14). No complications of probing were seen. CONCLUSION: In most children in the various age groups, epiphora disappeared. Thus, children do not need to be probed in the first year of life out of fear of failure at an older age. Whether or not probing shortens the duration of epiphora cannot be determined on the basis of either this study or the literature.

[Dacryocystography and dacryoscintigraphy in diagnosis of naso-lacrimal duct obstruction].

PURPOSE: To find the right diagnostic test through checking the drainage of lacrimal ducts. MATERIAL AND METHODS: Dacryocystography of lacrimal ducts was performed in 25 patients by using 0.5-1 ml of Lipidiol and conducting X rays in different head positions--3-4 photograph in A-P projection (exposition's parameters 85-90 kV and 12-15 mAs, distance lamp-table: 100-130 cm, Philips Diagnose 93). For stereo estimation--2 oblique photographs of head, deviated at 45 towards central body line. Patient is brought on vertical position and after 5 minutes radiography in A--P projection can show remaining contrast in lacrimal duct. Dacroscintigraphy was done in 200 patients by dropping in conjunctival sac 1 drop of sterile 99mTc, in dose 3.7-7.4 MBq (100-200 uCi). The patients head is immobilized on the support, close to detection head of gamma camera (ediso Nucline TH) with LEHR. Distribution of this drug was visible on the monitor and saved in the computer's memory. Data was registered during 10 minutes, summed up into end picture and then evaluated by sight. RESULTS: Many authors consider dacryoscintigraphy and dacryocystography as methods of choice in establishing correct diagnosis. High sensitiveness and mutual completion of both methods lets us quickly explain the reasons of epiphora and settle further management.

[Cannulation of congenital lacrimal duct obstruction].

During the development of a Czechoslovak silicone cannula for reconstructive surgery of the lacrimal passage-ways was elaborated the modification for the congenital obstruction. The surgical method imoles the probing and cannulation at the same time. probe with fixed cannula passed delicately through nasolacrimal duct via the upper or lower canaliculus to saccus lacrimalis. This probe overcomes the lateral part of the nose on the inspection of otorhinolaryngologist. The end of cannula was fixed by the stitch to skin near lacrimal punctum. The silicone tubing is left in situ for about three months.

[Time factors and instrumental treatment of lacrimal duct obstruction in childhood].

The authors evaluate the effectiveness of probing and rinsing of the lacrimal system in a group of 155 infants and young children (300 eyes) with congenital obstruction of the lacrimal pathways. The mean age during the first treatment was 3.7 months--range 21 days to 24 months. Patency of the lacrimal pathways was achieved in 83.49% of the group. In children treated before the 6th month the passage was restored in 91.30%. The effectiveness of procedures declines with advancing age. In the author's opinion it is best to make the operation between the 4th and 6th month of age. The operation under local anaesthesia ensures in the majority of children a rapid and permanent regression of complaints and a relatively small number of required repeated probings. At a later age the effectiveness of probes or rinsing declines and the solution is rather an indication for intubation of the lacrimal pathways or DCRS. One of the main still open questions for discussion is the optimal age for the operation. The author discusses also views of adverseries of probing and the problem of spontaneous canalization of the lacrimal pathways.
