Primary vs Secondary Endoscopic Dacryocystorhinostomy for Acute Dacryocystitis With Lacrimal Sac Abscess Formation: A Randomized Clinical Trial.

ABSTRACT:

Importance

Endoscopic dacryocystorhinostomy (EN-DCR) is emerging as the preferred procedure in the management of nasolacrimal duct obstructions. However, its safety and long-term efficacy in the setting of acute dacryocystitis with lacrimal sac abscess have not been well studied.

Objective

To compare outcomes of EN-DCR as primary treatment with EN-DCR as a secondary treatment after percutaneous drainage of lacrimal sac abscess in acute dacryocystitis.

Design, setting, and participants

This randomized clinical trial was conducted from October 1, 2012, to October 31, 2015, at a tertiary ophthalmic center. The assessors of success at postoperative year 1 were masked to the procedures received by the participants. All surgical procedures were performed by 2 oculoplastic s
