NCT ID: NCT00312689 Active, not recruiting - Clinical trials for Congenital Lacrimal Stenosis

Microbiological Examination of Children Operated for Congenital Lacrimal Stenosis

Start date: March 2006
Phase: N/A
Study type: Observational

Children with congenital lacrimal stenosis are treated by probing and intubation of the lacrimal drainage system. Hypothesis: Microbiological findings at the time of insertion and removal of the silicon intubation have an influence on the clinical outcome and success rate of the surgical treatment. Microbiological specimens are taken from conjunctiva and nasal mucosa during the two procedures under general anaesthesia and from the silicon tube after removal and examined for bacterial contamination.
