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<0.001, and P=0.004). An inverse correlation was found between DHEA-S and BUT values in the PCOS group (r=-0.296, P=0.043). Similarly, a negative correlation was also present between NLR and BUT values in the PCOS group (r=-0.322, P=0.027).


CONCLUSIONS
Dry eye can be well established by sensitive tests in patients with PCOS. The severity of dry eye may be correlated with the level of inflammation and hyperandrogenism.
