Association Between Dry Eye and Polycystic Ovary Syndrome: Subclinical Inflammation May Be Part of the Process

Purpose: To evaluate the changes in tear function in patients with polycystic ovary syndrome (PCOS) and establish whether there is a correlation between hormonal levels, novel hematologic biomarkers, and dry eye parameters. Material and Method: Forty-seven patients with PCOS and 43 age-matched patients with unexplained infertility were included in the control group. Follicle-stimulating hormone, luteinizing hormone, estradiol, thyroid-stimulating hormone, prolactin, dehydroepiandrosterone sulfate (DHEA-S), 17-OH progesterone, fasting and postprandial glucose, fasting insulin, and cholesterol metabolites were evaluated in both groups. In addition, the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio were obtained from a complete blood count. The Ocular Surface Disease Index (OSDI) questionnaire was administered, and all patients underwent tear break-up time (BUT) and Schirmer I tests. Bivariate correlations were investigated using Spearman correlation coefficient analysis. Results: The mean age of the PCOS group and the control group was 27.66 +/- 3.96 years and 29.28 +/- 6.83 years, respectively. Schirmer I test scores and BUT values were significantly lower and OSDI results were significantly higher in the PCOS group (P=0.003, P
