To evaluate the characteristics of bilateral nasolacrimal duct obstruction (NLDO) carriers and success rates of same day (simultaneous) or asynchronous (different day) bilateral dacryocystorhinostomy (DCR).
This retrospective study included patients with bilateral NLDO who underwent bilateral external DCR between January 2010 to August 2015 at the King Khaled Eye Specialist Hospital, Saudi Arabia. Postoperative success rate was considered as subjective perception of no tearing bilaterally or failure if unilateral or bilateral tearing persists after surgery. Data were statistically analyzed with P <0.05 indicating significance.
Of 57 patients undergoing bilateral DCR, 32 (56%) had same-day surgeries and 25 underwent asynchronous surgery. The median duration of follow up was 7 months. The success rates were similar for the same day group [61.3%–95% CI 49.4–73.2)] and for the asynchronous group [54.2% (95% CI 40.4–68.0)]. Success rate was not correlated to the age, gender, or use of stents.
The authors strongly recommend bilateral same-day external DCR to treat bilateral NLDO since the success rate of the procedure is similar to the asynchronous surgery, allowing a full treatment in just 1 operative visit.
