Abstract
Punctal stenosis is a common disorder of the punctum. It is an important cause of epiphora and accounted for 8% of all patients presenting with epiphora in a tertiary care oculoplastic practice [1–5]. Although numerous factors have been implicated as causative agents, the exact pathogenesis is still elusive. The widely believed hypothesis that has been supported by histological studies is a common mechanism involving inflammation leading to fibrosis and subsequent stenosis [2].
