Preoperative and postoperative records of 4 patients who presented with either a delay in blinking or lagophthalmos on the first postoperative day were evaluated. None of the patients had a history of facial palsy or any symptom of lagophthalmos. All 4 patients had undergone external DCR without silicone intubation under general anesthesia. Three of the patients had a delay in blinking, while one patient developed a 4-mm lagophthalmos postoperatively. A mild punctate keratopathy was observed in one patient. The condition resolved in all patients after an average of 8 weeks. (Turk J Ophthalmol 2014; 44: 413-5)
