- ItemAcesso aberto (Open Access)Complicações na dacriocistorrinostomia transcanalicular com laser diodo: complications(Conselho Brasileiro de Oftalmologia, 2009-08-01) Garcia, Eduardo Alonso [UNIFESP]; Cintra, Pedro Paulo Vivacqua Cunha; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To evaluate the complications of the use of diode laser in the treatment of acquired nasolacrimal obstruction. METHODS: Forty four procedures (transcanalicular dacryocystorhinostomy with diode laser with bicanalicular silicone tube intubation and local anesthesia) where performed from February 2002 to November 2007 in 41 patients (3 bilaterally), 32 women and 9 men. RESULTS: The most common intraoperative complications were disability to pass the Crawford probe (13.6%) and the laser probe (11.3%). Regarding postoperative complications, epiphora was the event of higher frequency (15.9%) followed by the non-intentional silastic extrusion by the patient (11.3%). CONCLUSION: Intraoperative and postoperative complications rate were similar of others articles that demonstrated the same surgical technique (with same laser).
- ItemAcesso aberto (Open Access)Dacriocistite aguda: relato de 2 casos(Sociedade Brasileira de Oftalmologia, 2011-02-01) Lorena, Silvia Helena Tavares [UNIFESP]; Silva, João Amaro Ferrari [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The adult lacrimal obstruction can be congenital or acquired. In the case of the acquired form, the etiology classifies in not-specific (it involves the coating epithelium and/or the vascular plexus submucosae of the lacrimal duct) and specific (infections, inflammations, tumours and iatrogenies). The diagnosis is established by means of the anamnesis and clinical evaluation based on semiology of the lacrimal sack. The patients with lacrimal obstruction present epiphora, acute pains and swelling, mostly in the region of the lacrimal sack causing ectasye of various degrees whichn culminate with cutaneous fistulization. The image exams routinely proposed for dacryocysto-graphy, which represent a great help in showing the best surgical technique for dacryocystorhinostomy, will be indicated as soon as the acute inflammatory state is treated.

- ItemAcesso aberto (Open Access)Etiologia da obstrução canalicular(Conselho Brasileiro de Oftalmologia, 2001-10-01) Bison, Simone [UNIFESP]; Scarpi, Marinho Jorge [UNIFESP]; Soccol, Ovídio; Tongu, Maira Tiyomi Sacata [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Santa Casa de São Paulo Seção de Vias LacrimaisPurpose: There are few Brazilian studies about canaliculus obstruction etiology. To analyze the various etiologies of the obstruction was the goal in the present study. Methods: The study was carried out on 63 lacrimal apparatus of 59 patients who were submitted to external examination, biomicroscopy, Jones' I and II tests and canaliculus measurement. Results: The most important etiologies were chronic dacryocystitis and failure of dacryocystorhinostomy (53.9%) followed by traumatisms caused by aggression, car accidents and a dog bite. Agenesis contributed with 9.5% and less frequent were canaliculus inflammations and infections, surgeries, radiotherapy and idiopathic obstructions. Conclusions: There is no diference between the findings of this study and those re-ported in the international literature.
- ItemSomente MetadadadosObstrução primária do ducto nasolacrimal: proposta de classificaçäo histopatológica(Universidade Federal de São Paulo (UNIFESP), 1996) Bison, Simone Haber Duellberg von Faber [UNIFESP]; Barros, Paulo Sergio de Moraes [UNIFESP]
- ItemAcesso aberto (Open Access)Resultados da conjuntivodacriocistorrinostomia com implante de prótese lacrimal de polietileno de baixa densidade(Conselho Brasileiro de Oftalmologia, 2002-01-01) Bison, Simone [UNIFESP]; Soccol, Ovídio; Scarpi, Marinho Jorge [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Santa Casa de São Paulo Departamento de OftalmologiaPurpose: To analyze the postoperative complications of conjunctivodacryocystorhinostomy with low-density polyethylene tube and the possible correlations between the various etiologies and complications and surgical success rate. Methods: The study was carried out on 35 lacrimal apparatus of 34 patients who were submitted to conjunctivodacryocystorhinostomy with low-density polyethylene tube during a six-year period, from August 1991 to November 1997. With the aim of studying the possible correlations between the findings (etiology x complications and etiology x success rate) exact Fisher's test was carried out. Results: The most important etiologies were chronic dacryocystitis and failure of dacryocystorhinostomy (53.9%) followed by traumatisms (16.3%). The complication rate was 74.3%. The surgical success rate in one intervention was 25.7%. After two or more surgeries, 17 tubes became pervious and well-located (48.6%). Unsuccessful procedures occurred in 25.7% of the lacrimal apparatus. There was no significant correlation between etiology and complication occurrence neither between etiology and surgical success. Conclusions: There is no difference between complications and success in this study and those reported in the international literature. These findings were not correlated with the obstruction etiology. The advantages of low-density polyethylene tube are its great availability, the easy manufacture in the intraoperative period according to the lenght and width needs of and, finally, it can be exchanged for borosilicate glass when the edema regress.
