[Schirmer test I and BUT (break-up-time) in patients treated with topical antiglaucoma drugs for a long time].

PURPOSE
The aim of this study was to evaluate Schirmer test I and BUT in patients after long-term topical antiglaucoma medication.


MATERIAL AND METHODS
59 glaucoma patients on stable regimen of one or two antiglaucoma drugs (for a minimum 1 year) and 30 healthy people were checked for changes of the precorneal tear film. Tear secretion was measured by Schirmer test I and stabilization of precorneal film by break-up time.


RESULTS
We found no influence of antiglaucoma drugs on tear secretion. Statistically significant decrease in break-up time was found in glaucoma patients.


CONCLUSIONS
Long-term topical antiglaucoma medication may alter precorneal film stabilization.
