Endoscopic DCR is an endonasal minimally invasive procedure to bypass an obstructed nasolacrimal duct by creating a direct fistula between the lacrimal sac and the nasal cavity. This is a retrospective case series review of the author's experience in endoscopic DCR in the period from 2007 to 2017. This series included 193 adult patients with a mean age of 47 years who underwent endoscopic DCR surgery. In this study, both primary and revision cases were reviewed including non-stented primary cases and bilateral simultaneous surgeries at the same session. Causes of failure in primary surgeries were stated, and indications of secondary cases were also reviewed. As a conclusion, endoscopic DCR remains the standard procedure in treating nasolacrimal duct obstruction with its consequent symptoms of epiphora, recurrent or chronic dacryocystitis.
