Long term follow up of nasolacrimal intubation in adults.
(41/129)
BACKGROUND/AIMS: The authors have previously reported a short term mean 15 month follow up of nasolacrimal intubation in adults. The effectiveness of this procedure for long term (mean 78 months) control of epiphoria is assessed here. METHODS: 65 eyes from 40 patients who underwent nasolacrimal intubation were followed. Mean age at intubation was 59.2 years. The mean follow up period was 6.2 years. The results were based on long term symptomatic improvement. RESULTS: Complete long term resolution of symptoms was reported in 50.7%. A partial improvement was reported in 38.5%, and no improvement in 10.7%. A better outcome was associated with a canalicular than nasolacrimal duct obstruction. On long term follow up 16.9% required dacrocysto-rhinostomy (DCR). CONCLUSION: Nasolacrimal intubation, a minimally invasive procedure is successful in the long term control of epiphora. Selection of patients with canalicular duct obstruction gives higher success rates with fewer patients subsequently requiring the DCR procedure. (+info)
Complications of mitomycin C therapy in 100 eyes with ocular surface neoplasia.
(42/129)
AIM: To determine the complications associated with mitomycin C (MMC) in the treatment of ocular surface neoplasia. METHODS: A retrospective and consecutive study of 100 eyes in 91 patients with ocular surface neoplasia treated with MMC in a single centre between November 1998 and January 2005. Outcome measures included complications of MMC and the treatment required for these complications. RESULTS: One to three 7 day cycles of topical MMC 0.04% four times a day were given to 59 eyes with localised corneal-conjunctival intraepithelial neoplasia (CIN), 19 eyes with diffuse CIN, six eyes with recurrent CIN, one eye with ocular surface squamous cell carcinoma, three eyes with primary acquired melanosis (PAM) with atypia, nine eyes with conjunctival malignant melanoma (MM), two eyes with sebaceous carcinoma with pagetoid spread, and one eye with recurrent atypical fibroxanthoma. Nine patients had bilateral CIN. 31 (34%) cases developed an allergic reaction to MMC and 14 (14%) eyes had epiphora secondary to punctal stenosis at a mean follow up period of 26.5 months. CONCLUSION: In the largest study looking at complications of topical MMC in the treatment of ocular surface neoplasia, allergic reaction and punctal stenosis are relatively common. Serious complications were not observed suggesting the safe use of MMC in mid-term follow up. (+info)
Clinical results of endoscopic dacryocystorhinostomy using a microdebrider.
(43/129)
PURPOSE: The success rate of endoscopic dacryocystorhinostomy has been increasing with the development of better instruments and techniques. We conducted this study to evaluate the clinical results of endoscopic dacryocystorhinostomy using a Microdebrider, which has also been used for functional endoscopic sinus surgery. METHODS: We selected 76 patients (with a total of 84 affected eyes) who had been diagnosed with a nasolacrimal duct obstruction. These patients underwent an endoscopic dacryocystorhinostomy using a Microdebrider, which removed both nasal mucosa and lacrimal sac mucosa and also trimmed the margins of the ostotomy site. We assessed patients' outcomes on an anatomical basis using a dye test and endoscopy, which were used to define the anatomical success. We also arbitrarily defined functional success as whether the subjective epiphora was absent. At a four to 18 month follow-up, we monitored the clinical course to examine any recurrent episodes. RESULTS: The symptoms were alleviated in 72 eyes, with a primary success rate of 85.7%. On nasal endoscopy, a functional failure was seen in four eyes. In these four eyes, the orifice was narrowed by the presence of either granulation tissue or conjunctivochalasis. By contrast, surgical outcomes were the anatomical failure in eight eyes. In these eight eyes, the orifice was obstructed by the presence of granulation tissue as well as the adhesion of nasal mucosa. CONCLUSIONS: Endoscopic dacryocystorhinostomy using a Microdebrider enabled us to make the large fistula while minimizing the damage of adjacent tissue. It might be the recommended surgery that reduces the complications and enhances the success rate. (+info)
A symptom survey and quality of life questionnaire for nasolacrimal duct obstruction in children.
(44/129)
PURPOSE: To develop and validate a new parental questionnaire addressing symptoms and health-related quality of life (HRQL) in childhood nasolacrimal duct obstruction (NLDO). DESIGN: Cross-sectional study. PARTICIPANTS: Children ages 6 to younger than 48 months with and without clinical signs of NLDO. METHODS: A new questionnaire was developed using semistructured interviews with parents of children with NLDO and through discussions with expert clinicians. Questionnaires were completed by parents of children with and without NLDO. Cronbach's alpha was calculated as a measure of internal-consistency reliability. Factor analysis was used to evaluate a priori subscales: symptoms and HRQL. Discriminant construct validity was assessed by comparing questionnaire scores between children with and without NLDO and between affected and unaffected eyes of children with unilateral NLDO. Instrument responsiveness was determined by comparing presurgical and postsurgical intervention scores in a subset of NLDO patients who underwent surgical treatment. MAIN OUTCOME MEASURE: The NLDO questionnaire score. RESULTS: Eighty-seven children were enrolled, 56 with and 31 without NLDO. All but 2 questions on the questionnaire showed a good distribution of responses, a high correlation with the rest of the questionnaire, and excellent discrimination between patients with and without NLDO. Cronbach's alpha values were good for the overall questionnaire (0.95), and for 2 predetermined subscales: symptoms (0.95) and HRQL (0.85). On a 0 to 4 scale, NLDO patients had worse scores compared with non-NLDO patients for both symptoms (mean difference, 2.1; 95% confidence interval [CI], 1.9-2.3) and HRQL (mean difference, 1.2; 95% CI, 0.9-1.5) subscales. The NLDO patients had worse scores before intervention compared with after intervention for both the symptoms (mean difference, 2.2; 95% CI, 1.6-2.9) and HRQL (mean difference, 1.4; 95% CI, 0.8-2.1) subscales. Finally, NLDO patients had worse symptom scores for affected eyes compared with unaffected eyes (mean difference, 2.3; 95% CI, 1.9-2.6). CONCLUSIONS: This novel NLDO questionnaire is useful in quantifying parental perception of symptoms and HRQL in childhood NLDO. The questionnaire may have a role in future clinical studies of NLDO.

Prospective study of incidence and severity of epiphora and canalicular stenosis in patients with metastatic breast cancer receiving docetaxel.
(45/129)
PURPOSE: To determine the incidence and severity of epiphora and canalicular stenosis in patients receiving docetaxel weekly or every 3 weeks. PATIENTS AND METHODS: In this prospective trial, each patient underwent an ophthalmologic examination and probing and irrigation of the lacrimal drainage apparatus at baseline and every 4 to 6 weeks after initiation of docetaxel. During each visit, epiphora and canalicular stenosis were graded. Patients with epiphora were treated with tobramycin and dexamethasone drops. If epiphora worsened or if findings on probing and irrigation suggested further canalicular narrowing, silicone intubation was offered. RESULTS: Twenty-eight patients received docetaxel weekly, and 28 patients received docetaxel every 3 weeks. Eighteen patients (64%) who received weekly docetaxel developed epiphora. Epiphora was mild in seven patients, moderate in five, and severe in six. Nine patients had resolution of epiphora with tobramycin and dexamethasone administration. Nine patients had worsened canalicular stenosis; six underwent surgery. The median cumulative docetaxel dose was 496.5 mg at onset of epiphora and 889.5 mg at surgery. Eleven patients (39%) who received docetaxel every 3 weeks developed epiphora. The median cumulative docetaxel dose at onset of epiphora in this group was 420 mg. Epiphora was mild in nine patients, moderate in one, and severe in one. Nine patients had resolution of epiphora with tobramycin and dexamethasone administration. Two patients underwent surgery. CONCLUSION: Epiphora occurred in 64% of patients in the weekly group and in 39% of patients in the every-3-weeks group. Moderate or severe canalicular stenosis was seen in about one-third of patients in the weekly group and in none of the patients in the every-3-weeks group. (+info)
Endoscopic dacryocystrhinostomy.
(46/129)
Endonasal endoscopic dacryocystorhinostomy (EN-DCR) is now a well-established procedure to relieve nasolacrimal duct obstruction, becoming its domain for the ENT surgeons indispensable. AIM: The aim of the present study is to report the experience of the Otorhinolaryngology Department of the University of Sao Paulo Medical School in the management of the obstruction of the drainage of the nasolacrimal system by EN-DCR, comparing with the results in literature. STUDY DESIGN: clinical retrospective. MATERIAL AND METHOD: We reviewed the medical records of 17 patients (17 eyes) that were submitted to EN-DCR between april 2001 and july 2004. We analysed: sex, age at the time of diagnosis, etiology, clinical findings, surgical technique, use of silicone tubes, follow-up and complications. RESULTS: Eight men and nine women, the age range was from 29 to 79 years (mean 42.6413.1 years), mean follow-up time: 15 months, presented a lacrimal clinic with epiphora. Powered DCR was performed in 06 cases and YAG LASER in 01 patient. Silicone tubes were used in all cases and left in place mean 7.9 weeks. The surgical success rate was 82,3%. CONCLUSION: EN-DCR showed one safe technique, with advantages in relation to the external technique. So ophthalmologists and ENT physicians must work in harmony to offer more benefits to its patients. (+info)
Endonasal dacryocystorhinostomy in children.
(47/129)
AIM: To verify whether our results with endonasal endoscopic dacryocystorhinostomy in children with nasolacrimal duct obstruction allow us to consider this technique a valid treatment alternative for children. STUDY DESIGN: clinical with transversal cohort. MATERIAL AND METHOD: Twenty-seven endoscopic endonasal dacryocystorhinostomies were performed in children 2 to 12 years of age for nasolacrimal duct obstruction. Previous probings in all patients were unsuccessful. The technique employed uncinectomy and a small lacrimal sac opening. Follow-up time was 3 months. RESULTS: Twenty-one surgeries (77,8%) were successful. The only complication was silicone prolapse in one case. CONCLUSION: Our results confirm endoscopic endonasal dacryocystorhinostomy as an acceptable and safe method for treating children with nasolacrimal duct obstructions that are resistant to probings.

Endoscopic dacryocystorhinostomy: creation of a large marsupialized lacrimal sac.
(48/129)
This retrospective study describes and evaluates the effectiveness of a modified technique of conventional endoscopic dacryocystorhinostomy (DCR) that minimizes the obstruction of a neo-ostium by creating an enlarged marsupialized lacrimal sac using mucosal flaps. Forty-two patients who had undergone 46 endoscopic DCR at a tertiary medical center, from 2002 to 2004, for correction of lacrimal system obstruction were investigated. The surgical technique involves elevation of a nasal mucosal flap, full sac exposure using a power drill, and shaping of the mucosal flap to cover denuded bone and juxtapose exposed sac mucosa. Postoperative symptoms and endoscopic findings of the neo-ostium were evaluated. Mean duration of follow-up was 5.9 months. An eighty-three percent primary success rate was observed, without any serious complications. Obstruction of the neo-ostium with granulation tissue was observed in eight cases, among which six underwent revision with success in all cases. Overall, 44 (96%) of 46 cases experienced surgical successes. Endoscopic DCR, a procedure in which a large marsupialized lacrimal sac is created from mucosal flaps, yields a very satisfactory success rate with straightforward and highly successful revision available for those in whom the primary procedure yields a substandard result.
