Ophthalmology, 10/29/09
Satchi K et al. – Double lower lacrimal puncta may be associated with epiphora. In younger patients, tearing may be due to associated congenital anomalies of the nasolacrimal system. A proportion of patients presenting with onset of tearing in adulthood have patent lacrimal systems and otherwise normal adnexal examination results, suggesting that the presence of double puncta may be associated with compromised canalicular function. Reflux of tears through the accessory canaliculus is a potential mechanism and would be consistent with a recently proposed 2–compartment model of lacrimal canalicular drainage.
