Clinical and Functional Evaluation of the Effectiveness of Dacryocystorhinostomy in Dry Eye Syndrome

Abstract

This study evaluated the clinical and functional effectiveness of dacryocystorhinostomy (DCR) in patients with dry eye syndrome (DES). One hundred patients with DES who underwent DCR received comprehensive ophthalmological examination before and after surgery, including tear break-up time (Norn test), Schirmer I test, DES severity grading, subjective symptom scores, and conjunctival hyperemia assessment. After DCR, statistically significant improvements were observed across all parameters (p < .001): tear film stability increased by 86% (Norn test: 5.9 ± 0.9 to 11.0 ± 1.5 s), tear secretion doubled (Schirmer I: 6.9 ± 1.0 to 13.8 ± 1.8 mm), DES severity decreased by 46%, subjective complaints decreased by 79%, and conjunctival hyperemia decreased by 78%. DCR significantly improves tear film stability, tear production, and ocular surface condition in patients with DES. Restoration of lacrimal drainage positively influences tear system function and should be considered an integral component of comprehensive DES management.
