AIM: To evaluate the occurrence of co-existing congenital nasolacrimal duct obstruction (CNLDO) and other lacrimal anomalies in eyes with congenital glaucoma (CG). METHODS: Retrospective analysis of children aged ≤1-year with co-existing CG and CNLDO seen between 1998 and 2019, treatment interventions and outcomes. RESULTS: During the study period, 1993 children had CG and 6203 children had CNLDO, among the children aged 1-year or less. Of these, 51 children (73 eyes) had co-existing CG and CNLDO. The prevalence of CNLDO in CG was 2.5% (51/1993) and the prevalence of CG among CNLDO was 0.8% (51/6203). Median age (Interquartile range, IQR) was 53 days (IQR: 8, 155), when they were diagnosed with CG. Among the children with CNLDO, 68 eyes (93.1%) had simple CNLDO, and 5 eyes (6.9%) had complex CNLDO. Associated lacrimal anomalies were present in 7/73 eyes, including congenital lacrimal fistula in two eyes, upper punctal agenesis and upper mid-canalicular obstruction in two eyes each, and upper single canalicular-wall hypoplasia in one eye. Lacrimal syringing and probing were successful in 69/72 eyes (95.8%), and failed in 3 eyes (4.2%). These 3 eyes had complex CNLDO and underwent Dacryocystorhinostomy (DCR) with Mitomycin-C and intubation. Sixty-two eyes underwent combined trabeculotomy and trabeculectomy, and two eyes underwent trabeculectomy. Median age at glaucoma surgery was 87 days (IQR: 54, 193). Median time delay for glaucoma surgery after probing was 18 days (IQR: 12, 35). CONCLUSION: Among children aged ≤1-year presenting with congenital glaucoma coexisting lacrimal drainage anomalies was noted in 2.5% and simple CNLDO was the commonest. Early intervention is of paramount importance to prevent sight-threatening intraocular infection with CNLDO, and to minimize the delay of glaucoma surgery. The outcomes of lacrimal probing were excellent, however complex CNLDO required DCR.
