Conjunctival specimens were collected by impression cytology and analyzed by light microscopy using Nelson’s grading scheme (grades 0–3). This classification is based on the nucleus-to-cytoplasm ratios of epithelial cells and the numbers of goblet cells, with grade 2 considered abnormal.Results: The medication group had significantly shorter TBUT (median [interquartile range]: 6.0 seconds [5.0–8.0 seconds] vs 9.5 seconds [6.0–12.3 seconds]; P<0.03), greater fluorescein staining (1.0 [0.75–1.25] vs 0 [0–0.25]; P<0.001), and higher impression cytology grade than the control group (median [range]: 1.0 [1:2 to 1:6] vs 0.6 [1:2 to 1:4]; P<0.001). The increasing number of drops instilled per day was associated with an increase in fluorescein staining (Spearman’s rho r=0.475; P<0.001) and shorter TBUT (r=-0.278; P=0.014). The OSDI did not discriminate between the two groups.Conclusion: Clinical tests and impression cytology showed ocular surface damage in patients using preserved antiglaucoma medications. However, there was no statistically and clinically significant difference in symptoms measured by OSDI score between the medication and control groups.
