The value of lacrimal scintigraphy in the assessment of nasolacrimal duct obstruction was determined by comparing the results with syringing in 67 patients (83 eyes). As expected, of 28 lacrimal drainage systems which were obstructed on syringing, 23 (82%) had abnormalities of tear drainage on scintigraphy. However, in 55 lacrimal drainage systems that were patent on syringing, 19 (35%) were normal, but in 36 (65%) abnormalities not apparent on syringing were detected on scintigraphy. Thus scintigraphy is a very useful technique in the assessment of nasolacrimal duct obstruction particularly in systems patent on syringing. Since the site of obstruction can be determined, lacrimal scintigraphy can facilitate the planning of the appropriate surgery.
通过将67例患者（83只眼）泪道闪烁造影的结果与泪道冲洗的结果进行比较，确定了泪道闪烁造影在评估鼻泪管阻塞中的价值。正如预期的那样，在28个经泪道冲洗显示阻塞的泪道引流系统中，23个（82%）在闪烁造影中存在泪液引流异常。然而，在55个经泪道冲洗显示通畅的泪道引流系统中，19个（35%）正常，但在36个（65%）经泪道冲洗未显示异常的系统中，闪烁造影检测到了异常。因此，闪烁造影在评估鼻泪管阻塞中是一种非常有用的技术，特别是对于经泪道冲洗显示通畅的系统。由于可以确定阻塞部位，泪道闪烁造影有助于规划合适的手术。
