Purpose:
To investigate the effects of probing of lacrimal passage on congenital dacryocystitis.
Methods:
474 consecutive infants with congenital dacryocystitis were treated with probing of lacrimal passage. The data were retrospectively analyzed.
Results:
In 474 eyes, there were 360 and 122 eyes with or without membranous block respectively, and 356 (98.89%) and 107 eyes (85.25%) with or without membranous resistance were respectively cured with probing of lacrimal passage; there were 12 eyes with stenosis and 8 eyes (66.67%) were cured. In operation, 1 and 3 eyes were respectively suffered from subcutaneous edema and laceration of canaliculus, but there was no baby suffered from infection or asphyxia.
Conclusions:
The effects of probing of lacrimal passage were related to the causes of obstruction of lacrimal passage, and it is very important to scrupulously feel in probing lacrimal passage.
