We studied the prevalence, symptoms and signs, both before and after probing, in patients with CNLDO diagnosed between 2010 and 2017 at Instituto Fundaci\u00f3n Conde deValenciana.\r\nResults: The prevalence at our hospital of congenital nasolacrimal duct obstruction in children less than 1 year of age was 16.1%. 71 eyes of 56 patients undergoing probing were analyzed. 61% of patients were male. The right eye was affected in 46.4%.The average age of diagnosis of CNLDO was 10.2\u00b17.6 months. 84.5% consulted for excessive tearing and 73.2% because of eye discharge. On ophthalmological examination, 71.8% had increased tear meniscus and 45.1% had discharge from punctum when digital pressure was applied to the lacrimal sac. The average age at the time of probing was 14.1\u00b18.4 months. Subsequent to the probing, only 21.1% reported presence of tearing and 5.6% reported ocular discharge, both with a statistically significant reduction (p&lt;0.05 from pre-op). After probing, only 16.9% of eyes had increased tear meniscus and 11.3% presented discharge from punctum after pressure at the lacrimal sac. Both decreases were statistically significant (p&lt;0.05). 2 eyes (2.82%)of 2 patients required a second probing to obtain full resolution.\r\nConclusion: Probing was successful in 76.1% of eyes. Success was observed even inpatients over 2 years of age. There was a statistically significant decrease of both signs and symptoms of CNLDO with lacrimal probing.<\/jats:p>","DOI":"10.3126\/nepjoph.v11i2.27827","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T07:24:23Z","timestamp":1582874663000},"page":"189-196","source":"Crossref","is-referenced-by-count":1,"title":["Management of Congenital Nasolacrimal Duct Obstruction with Probing, Experience in a Mexican Eye Center"],"prefix":"10.3126","volume":"11","author":[{"given":"Francisca","family":"Zuazo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osiris Olvera","family":"Morales","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 L.
