The Clinical Outcome of Silicone Tube Intubation According to Nasolacrimal Duct Obstruction Sites by Dacryoscintigraphy.

Purpose: To evaluate clinical outcome of silicone tube intubation in lacrimal passage obstruction according to the lacrimal passage obstruction patterns by dacryoscintigraphy. Methods: Fifty-nine eyes of 52 patients complaining of epiphora were divided into three groups pre-sac (group 1), intra-sac (group 2), and intra-ductal (group 3) types by dacryoscintigraphy. We confirmed the obstructive sites of lacrimal passage by probing with Bowman...
