Abstract
A method of evaluating clearance of fluorescein dye instilled into tear film having a greater sensitivity and specificity for diagnosing a tear film disorder as the cause of a patient's ocular irritation and ocular surface disease than can be achieved using the traditional methods. The inventive method can be performed using a diagnostic kit for evaluating tear fluorescence clearance in which the concentration of tear fluorescein is visually quantified via a color standard.
