At a glance: catalogue of systemic associations of congenital lacrimal drainage anomalies.

Abstract

Congenital lacrimal drainage anomalies have several syndromic and non-syndromic associations reported in the literature. While the information is exhaustive, it may not be useful if someone wants to know the associations based on individual lacrimal anomalies quickly. For example, if someone wants to know the systemic associations of supernumerary punctum, it entails scanning of all the syndromes to note which of them reported the specific anomaly. Besides, several new associations have been reported in the last four years. Hence, the need was felt for a separate categorization in a catalogue form to access all the associations immediately, in an alphabetical order, and easily reference them. The present exercise allowed us to catalogue 73 systemic associations of CNLDO, 37 for punctal agenesis, 20 for punctal dysgenesis, 17 for congenital lacrimal fistulas, 9 for canalicular wall dysgenesis, and three each for supernumerary punctum and pediatric functional epiphora.
