To explore the application value of computed tomography (CT) dacryocystography in children lacrimal diseases.
Retrospective case series. The results of CT dacryocystography in 300 children (395 eyes) with lacrimal diseases from October 2009 to October 2011 in Beijing Children Hospital were analyzed retrospectively.
Among 240 children (326 eyes) with congenital nasolacrimal duct obstruction, the sites of obstruction were in the common canaliculus or upper position in 6 eyes (1.8%), in the lacrimal sac in 38 eyes (11.7%), at the borderline between lacrimal sac and nasolacrimal duct in 213 eyes (65.3%) and at the terminal of nasolacrimal duct in 69 eyes (21.2%). CT dacryocystography could display the obstruction position of lacrimal duct in congenital nasolacrimal duct obstruction. In unilateral congenital nasolacrimal duct obstruction, CT dacryocystography indicated that nasolacrimal canal in affected side were much larger than that in normal side. It could show the destruction of lacrimal soft tissue and the fossa of lacrimal sac in traumatic lacrimal duct obstruction. CT dacryocystography was also the main subsidiary method for the diagnosis of congenital dacryocystocele, congenital nasolacrimal canal agenesis and lacrimal sac diverticula.
CT dacryocystography can provide important aspects for the diagnosis and treatment of children lacrimal diseases. Therefore, it can be used as an important image examination method in children with lacrimal diseases.
探讨计算机断层扫描（CT）泪囊造影在儿童泪道疾病中的应用价值。
回顾性病例系列研究。对2009年10月至2011年10月在北京儿童医院就诊的300例（395眼）泪道疾病患儿的CT泪囊造影结果进行回顾性分析。
在240例（326眼）先天性鼻泪管阻塞患儿中，阻塞部位位于泪小管或其上方者6眼（1.8%），位于泪囊者38眼（11.7%），位于泪囊与鼻泪管交界处者213眼（65.3%），位于鼻泪管末端者69眼（21.2%）。CT泪囊造影可显示先天性鼻泪管阻塞时泪道的阻塞部位。在单侧先天性鼻泪管阻塞时，CT泪囊造影显示患侧鼻泪管较健侧增粗。它还能显示外伤性泪道阻塞时泪囊软组织的破坏及泪囊窝情况。CT泪囊造影也是诊断先天性泪囊膨出、先天性鼻泪管缺如及泪囊憩室的主要辅助检查方法。
CT泪囊造影可为儿童泪道疾病的诊断和治疗提供重要依据。因此，它可作为儿童泪道疾病重要的影像学检查方法。
