Objective To observe the morphology of the inferior orifice of the nasolacrimal duct of the patients with presaccular lacrimal obstruction by using 30o ear endoscope and provide the basis for the CT retrograde intubation dacryosystography. Methods 54 patients (75 eyes) with presaccular lacrimal obstruction from May 2011 to March 2012 were involved in this study, including 3 cases (5 eyes) of upper and lower lacrimal punctum atresia, 15 cases (24 eyes) of superior and inferior canalicular obstruction, 18 cases (28 eyes) of common canaliculus obstruction, 18 cases (18 eyes) of previous laceration of superior and inferior canalicular. All patients underwent the endoscopy by using 30o ear endoscope and the imaging characteristics of the inferior orifice of nasolacrimal duct was obtained. Results 54 subjects (75 eyes) participated in the study, 66 eyes were confirmed that the inferior orifice of nasolacrimal duct was opening, the opening rate being88% (Of the 66 eyes, stimulated Hanser valve of 1 case covered the orifice of nasolacrimal duct and led to linear closure of the orifice) . 9 eyes were confirmed the atresia orifice of nasolacrimal duct，accounting for 12%. According to the shape of the inferior orifice, it was divided into three types: oval large (30 eyes, 45.45%), triangular fissure (12 eyes, 18.18%), strip fissure (24 eyes, 36.36%).In the 21 cases (42 eyes ) of the binocular sick patients, 15 cases (30 eyes, 71.42% ) of different forms and 6 cases （12 eyes，28.57%）of the same forms of bilateral opening inferior orifice of the nasolacrimal duct. Conclusion It is practicable to observe the location and morphology of the opening inferior orifice of the nasolacrimal duct for the patients
