本文用泪道插管造影(intubation dacryo-cystography,IDCG)与泪道定量化核素造影(quan-titative lacrimal scintillography,QLS)对正常泪道进行了调查,获得了有意义的结果。用 IDCG 对134人268正常眼进行了调查,并采用数据化分析方法来评价 IDCG 结果,发现泪道随年龄增长而变化,女性泪道特别是老年女性发生的变化尤为明显,其变化特征是趋向于阻狭性疾息的形成,它们包括泪小管距泪囊项端距离变小、泪囊下口横径变小、鼻泪管骨性和膜性部窄径变小。用 QLS 对61人122正常眼的调查结果表明随着年龄增长,泪液导流功能逐渐溅弱,包括结膜囊排出多余液体的能力和泪道排泄功能。这样,无论从解剖方面还是从功能方面,老年人尤其是老年女性都具有易发生泪道阻狭性疾患的倾向。本文还讨论了泪道疾患发病因素与性别及年龄增长的关系。
In this paper, normal lacrimal passages were investigated by intubation dacryo-cystography (IDCG) and quan-titative lacrimal scintillography (QLS), and significant results were obtained. Using IDCG to survey 134 normal 268 eyes, and using data analysis to evaluate the IDCG results, it was found that lacrimal duct changes with age, especially in female lacrimal passages, especially elderly women, the change is characterized by trends In the formation of resistance to stenosis, they include the distance from the lacrimal sac, the diameter of the lacrimal sac, the diameter of the lacrimal sac, the diameter of the nasolacrimal duct and the narrowing of the membranous lesion. The results of a survey of 61 normal subjects with QLS using QLS showed that tears gradually weakened as the age increased, including the ability of the conjunctival sac to drain excess fluid and lacrimal duct excretion. In this way, the elderly, especially older women, have a tendency to develop lacrimal duct stenosis, both anatomically and functionally. This article also discusses the relationship between the incidence of lacrimal disease and gender and age.
