An observational study was designed to research the bacteriology and pathogen drug sensitivity of chronic dacryocystitis in China and optimize antibiotic therapy.
For patients diagnosed with chronic dacryocystitis，we will collect the secretions after lacrimal passage irrigation, note the characters of the secretions and send the secretions for bacteria culture, analysis and pathogen drug sensitivity.
