Abstract

The complaint of tearing may be due to 1) partial or complete obstruction of the excretory mechanism, 2) increased lacrimal secretion, or 3) decreased basic lacrimal secretion. So the physician should ascertain whether an excess of tears or obstruction of excretory mechanism is present. The most widely used tests for this purpose are the Schirmer test, Jones test and fluorescein dye disappearance test. The Jones test consist of Jones I test and Jones II test, which determine the functional and anatomical integrity of the lacrimal excretory system. In this study, Schirmer test, Jones test and fluorescein dye disappearance test were performed on 400 normal and 100 abnormal eyes to determine the secretion and excretion of tears.
