We report the first case of supernumerary puncta and canaliculi presented with canaliculitis. A-59 year-old gentleman presented with painful swelling of the left lower lid for a week, which was associated with epiphora. The swelling was confined to the nasal aspect of the left lower lid (0.5×0.5 mm) with inflamed overlying skin. Two puncta (0.5 mm apart) were noted. The outer punctum at the normal anatomical position was a cul-de-sac while the inner punctum it the caruncle was patent. We described the embryology leading to supernumerary puncta and canaliculi to explain the paradoxical patency of the abnormally located punctum as well as the pathomechanism leading to canaliculitis. The patient was treated with oral cloxacillin 500 mg, 6 hourly for 5 days; the cellulitis subsided after three days.
我们报告首例伴有泪小管炎的额外泪点和泪小管病例。一名59岁男性患者，左眼下睑疼痛性肿胀一周，伴有溢泪。肿胀局限于左眼下睑鼻侧（0.5×0.5毫米），上方皮肤发炎。可见两个泪点（相距0.5毫米）。正常解剖位置的外侧泪点为盲端，而泪阜处的内侧泪点通畅。我们描述了导致额外泪点和泪小管的胚胎学，以解释异常位置泪点的反常通畅以及导致泪小管炎的发病机制。患者接受口服氯唑西林治疗，500毫克，每6小时一次，共5天；蜂窝织炎在三天后消退。
