There male predominance (61.5%), which also present subgroups. most frequent complete (NLDO, 55.4%), followed partial (17.7%) bony NLDO (11.5%). 87% eyes, initial performed dacryocystorhinostomy (10%). Mono- or bi-canalicular lacrimal drainage system intubation used 86% eyes. Conclusion AAO-based diagnostic an individualized regimen yielded excellent 96% unselected These independent patient gender.
