Impression specimens were obtained from the bulbar conjunctiva of 146 eyes of 73 healthy volunteers (mean age, 52 years). Goblet cell densities and nuclear‐cytoplasmic (N/C) ratio were determined. Break‐up time (BUT), Schirmer‐I test (S‐I), Rose Bengal scores (RBs) were also recorded. Using a simple linear regression analysis, no correlation between the number of Goblet cells and age, BUT and S‐I was found. Negative correlation with RBs ( P = 0.05) was found. The N/C ratio has a negative correlation ( P < 0.01) with age and RBs and a positive correlation with BUT ( P < 0.01) and S‐I ( P = 0.03).
