Abstract
AIM: To report the clinical profile, endoscopic dacryocystorhinostomy (En-DCR) management, and acute dacryocystitis (AD) outcomes in China. METHODS: Clinical data of 554 adult AD patients (554 eyes) who presented in 7 tertiary eye care centers for 10y from Jan 2010 to Mar 2020 were retrospectively analyzed. Clinical profile, En-DCR management, and outcomes of all cases were recorded. The anatomical and functional success were evaluated for 12mo post-operation. RESULTS: The analysis included 149 males and 368 females with a median age of 55.2y (range: 18-84y). There were 459 eyes with a history of epiphora or purulent secretion. The time between a symptom of lacrimal duct obstruction and acute onset was 1 to 540 (66.1±58.2)mo. Fifty-nine eyes had a history of the previous acute attack. Seventy-four eyes developed a cutaneous fistula, while 11 eyes had post septal cellulitis pre-operation. En-DCR with an anatomical success of 91.7% and functional success of 90.1%. The success rate of the patients with a history of acute episodes and the preoperative fistula was lower than the overall success rates. CONCLUSION: En-DCR can be performed during an acute episode in AD with a success rate of over 90%.
