A 15-year-old female was found on routine clinical examination to have bilateral asymptomatic congenital fistulae of the lacrimal glands. The fistulae opened into the conjunctival sac at the external canthus of both eyes. Temporary occlusion of these openings produced an immediate and significant reduction in tear secretion in both eyes.
一名15岁女性在常规临床检查中被发现患有双侧无症状先天性泪腺瘘管。瘘管开口于双眼外眦的结膜囊。临时堵塞这些开口会使双眼泪液分泌立即且显著减少。
