Abstract:AIM:To observe the difference of different intubation to obstruction of lacrimal passage after laser recanalisation and analyze it.METHODS:Totally there were 179 cases (299 eyes) with canalicular obstruction caused by various reasons. According to causes, cases were divided into three groups, among which 43 cases(74 eyes)were lacrimal canalicular obstruction group, 82 cases (134 eyes) were nasolacrimal duct obstruction group,54 cases(91 eyes) were lacrimal canalicular combined with nasolacrimal duct obstruction group. Lacrimal canalicular obstruction group was divided into two groups randomly:silicone intubation group 37 eyes, silk group 37 eyes. Nasolacrimal duct obstruction group was divided into three groups randomly:silicone intubation group 44 eyes, silk group 44 eyes, T-silicone intubation group 46 eyes. Lacrimal canalicular combined with nasolacrimal duct obstruction group was divided into two groups randomly:silk combined with T-silicone intubation group 45 eyes, silicone intubation with canalicular expansion tube group 46 eyes. The mean follow-up was 3-6 months, recovery of lacrimal passage drainaging tears function was observed and the therapeutic effect was compared among the groups.RESULTS:The curative and effective rates of the seven groups (lacrimal canalicular obstruction:silk group, silicone intubation group; nasolacrimal duct obstruction:silk group, silicone intubation group, T-silicone intubation group; lacrimal canalicular combined with nasolacrimal duct obstruction:silk combined with T-silicone intubation group, silicone intubation with canalicular expansion tube group) were 89.2% and 8.1%, 62.2% and 21.3%, 52.3% and 34.1%, 59.1% and 34.1%, 80.4% and 8.7%, 82.2% and 6.67%, 60.9% and 19.6% respectively.CONCLUSION:Clinical results show that the selection of indwelling things should based on the position, severity, course of disease, treatment conditions and compliance of the patient. In order to achieve the best curative effect, the indwelling things should be chosen personally according to specific condition of each patient.
