Xylometazoline hydrochloride nasal spray combined with laser artificial nasolacrimal duct implantation for nasolacrimal duct obstruction / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To study the role of xylometazoline hydrochloride nasal spray in combination therapy of nasolacrimal duct obstruction and to investigate the effect of nasal inflammation on nasolacrimal duct obstruction. <p>METHODS: Totally 279 patients with nasolacrimal duct obstruction were collected, who received lacrimal passage irrigation, CT angiography for lacrimal passage and nasal endoscope before treated by lacrimal laser forming and artificial nasolacrimal duct implantation combined with xylometazoline hydrochloride nasal spray. In group A, 137 patients were treated with antibiotic eye drop and non-steroidal anti-inflammatory drugs after operations. In group B, 142 patients were treated with xylometazoline hydrochloride nasal spray besides the same treatment for group A. <p>RESULTS:In the 279 patients 217(77.8%), in which 105 cases(76.6%)were in group A and 112 cases(78.9%)were in group B, were suffered with nasal inflammation, including nasal mucosal hyperemia, inferior turbinate hypertrophy, middle turbinate hypertrophy. At 3mo after the ducts were drawn, efficacy of group B was 95.8%, which was significant better than that of group A(86.1%, <i>P</i><0.05).<p>CONCLUSION: Nasal inflammation was an important factor in the incidence of nasolacrimal duct obstruction, which shoud pay more attention in the process of diagnosis and treatment. Combination therapy could improve the cure rate of nasolacrimal duct obstruction.

Analysis on pathogenic bacteria and drug sensitivity of canalicular inflammation / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the pathogenic bacteria and drug sensitivity in cases of canalicular inflammation. ●METHODS: Lacrimal sac secretion from 57 cases ( 57 eyes) with canalicular inflammation. used to do bacterial cultures and drug sensitivity tests. Grind open the sulfur particles from canaliculus for bacterial smear. ●RESULTS:After squeeze canalicular, there are 56 sulfur granules from 57 patients. All of the Sulfur particles smears were found in actinomycetes. A total of 55 from 57 cases of lacrimal secretions for bacterial culture were positive, and 63 strains were cultured. The main pathogen are Staphylococcus epidermidis, Streptococcus viridans and pneumococcus. Drug susceptibility test results showed that:rifampicin, cefoxitin, chloramphenicol, and mezlocillin are sensitivity. ●CONCLUSION:Actinomycetes were the main pathogens to canalicular inflammation, and most of the presence of co- infection with other bacteria. Rifampin, cefoxitin, chloramphenicol, and mezlocillin are sensitivity canalicular inflammation.
