Tear film flow and stability studies were carried out in patients suffering from chronic dacryocystitis by performing Schirmer test-I and tear film break-up-time (BUT) measurements. The results of Schirmer's test corroborated the theory that a reduced out flow of tears causes a compensatory reduced tear secretion. The results of break-up-time confirm the fact that BUT is independent of outflow of tears in patients with epiphora.
通过进行泪液分泌试验-I和泪膜破裂时间（BUT）测量，对患有慢性泪囊炎的患者进行泪膜流动和稳定性研究。泪液分泌试验的结果证实了泪液流出减少会导致代偿性泪液分泌减少这一理论。破裂时间的结果证实了这样一个事实，即对于溢泪患者，泪膜破裂时间与泪液流出无关。
