title: Study of tear film flow and stability in chronic dacryocystitis.
abstract: 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.
