[The influence of ocular surgery for lacrimal secretion].

Dry eye syndrome remains a constant health problem while more and more patients are being involved and final data concerning the etiopathology is still missing. This study investigates the hypothesis that ocular surgery inflicts damage on the tear production (regarding quantity, quality or the compositional aspect). Ocular symptoms were registered with the help of a questionnaire. Lacrimal tests were applied before and after surgery at 6 weeks. Basic and reflex tear secretion was differentiated through Schirmer tests and tear quality was assessed with BUT. Proteomic analysis (global proteins, electrophoresis) and conjunctival biopsy was realized before surgery. Open eye surgery altered tear secretion in 91% of the 22 patients examined.
