Objective: To determine whether the history of chronic conjunctivitis increases the likelihood of epiphora after an external dacryocystorhinostomy (Ex-DCR) and to elucidate other factors that may affect the prognosis of this surgery. Methods: This is a retrospective case-controlled study. Patients who had epiphora after an Ex-DCR were compared with patients who did not present epiphora. Medical history of conjunctivitis, use of antiglaucomatous drops, rhinitis, and nasal pathology were evaluated. Results: A total of 129 adult patients undergoing external DCR were evaluated, of which 73% had decreased tearing. Forty-five percent of the patients who continued with epiphora had a history of conjunctivitis, compared to the 20% of those who did not (p = 0.003). At the same time, the 20% of those who continued with epiphora had a history of rhinitis compared to the 8% of those who did not (p = 0.043). Conclusion: Patients with a history of chronic conjunctivitis are less likely to improve the epiphora after performing an Ex-DCR. We consider that it is important to evaluate this antecedent before surgery.
