A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a lacrimal sac biopsy was taken. Histopathology revealed florid chronic inflammation, with abundant granular brown pigment and polarisable crystals suggestive of an exogenous material in the lacrimal sac mucosa compatible with mascara. After initial improvement, her epiphora has recurred 1-year postoperatively, but her ocular discharge has resolved. Mascara-induced conjunctival pigmentation is well established. However, there are very few published reports of nasolacrimal duct obstruction due to mascara. Since cosmetic application of mascara and kohl eyeliner is widespread, patients and practitioners should be aware of their potential to migrate into the lacrimal apparatus and cause chronic inflammation with secondary nasolacrimal duct obstruction.
