Abstract
The cornea is a hormone-responsive tissue that responds to changing levels of female sex hormones. This review focuses on the structural and functional changes in the human cornea associated with the hormonal milestones of menarche, pregnancy, and menopause, as well as consequences stemming from the use of exogenous sex hormones for fertility control and replacement. Articles were identified by searching PubMed without language or region restrictions. The primary outcomes evaluated were changes in central corneal thickness (CCT), intraocular pressure (IOP), and quality of the ocular tear film. The potential impact of hormone-associated changes on the diagnosis and surgical management of common eye diseases, as well as the potential use of sex hormones as therapeutic agents is also considered. Understanding the physiological effects of female sex hormones on the cornea is important because that knowledge can shape the management decisions physicians and women face about ocular health across their life stages.

Abstract
Many factors in the domains of mental, physical, and social health have been associated with various ocular surface diseases, with most of the focus centered on aspects of dry eye disease (DED). Regarding mental health factors, several cross-sectional studies have noted associations between depression and anxiety, and medications used to treat these disorders, and DED symptoms. Sleep disorders (both involving quality and quantity of sleep) have also been associated with DED symptoms. Under the domain of physical health, several factors have been linked to meibomian gland abnormalities, including obesity and face mask wear. Cross-sectional studies have also linked chronic pain conditions, specifically migraine, chronic pain syndrome and fibromyalgia, to DED, principally focusing on DED symptoms. A systematic review and meta-analysis reviewed available data and concluded that various chronic pain conditions increased the risk of DED (variably defined), with odds ratios ranging from 1.60 to 2.16. However, heterogeneity was noted, highlighting the need for additional studies examining the impact of chronic pain on DED signs and subtype (evaporative versus aqueous deficient). With respect to societal factors, tobacco use has been most closely linked to tear instability, cocaine to decreased corneal sensitivity, and alcohol to tear film disturbances and DED symptoms.

Abstract
Purpose: The purpose of this prospective study was to compare the tear film pattern, meibomian gland (MG) losses in patients with polycystic ovary syndrome (PCOS) and healthy individuals in the control group, and to examine the correlation between peripheral blood values and findings in patients with PCOS. Methods: Eighty-one eyes of 81 patients with PCOS and 78 eyes of 78 healthy individuals were included in this study. Mean noninvasive first tear film break-up time (NIF-BUT) values and the mean noninvasive average tear film break-up time (NIAvg-BUT) values of all breaking-up occurring in the test were compared. MG losses were compared between the groups. In the second step of this study, we examined the correlation between NIF-BUT and NIAvg-BUT values and MG losses with inflammatory parameters. Results: NIF-BUT values were 7.21 ± 5.75 and 10.18 ± 5.90 s, respectively, in PCOS and control groups (P = 0.001). Loss of MG in the upper eyelids (SM-SCL) of PCOS and control group was 39.81 ± 16.34 and 17.84 ± 9.48, respectively (P = 0.000). Positive correlation was detected between SM-SCL value and neutrophil/lymphocyte ratio; platelet/lymphocyte ratio (P/L); and systemic immune-inflammation index, the value obtained from platelet count × (neutrophil/lymphocyte). Conclusion: Increased tear film instability and increased MG loss rates were detected in PCOS patients. In addition, we found a positive correlation between MG losses and inflammatory indices of patients with PCOS. We think that inflammatory processes also provide an additive effect, in addition to hormonal changes on the physiopathological process on the ocular surface in patients with PCOS.

Abstract
As all the structures of the human eye are characterized by sex hormone receptors, this study tested the hypothesis that assisted reproductive technology (ART) treatment influences visual function and ocular morphology in women who have undergone ART treatment and children born as a result of ART treatment. A systematic literature search of all original articles published up to August 2018 was performed using the PubMed database, including all original studies available in the literature. Review articles, studies in which participants underwent mixed interventions (i.e. other than ART treatment), studies reporting data on ocular malformations in ART offspring, and studies written in languages other than English were excluded. All selected articles were analysed to assess the level of evidence according to the Oxford Centre for Evidence-Based Medicine 2011 guidelines, and the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation system. Although sparse data suggest that ART treatment can influence visual function and ocular morphology in women who have undergone ART treatment and children born as a result of ART treatment, the available evidence is inconclusive given its low level and quality. More high-quality research is needed to assess the potential interaction between ART treatment and the eye.

Abstract
PURPOSE This study asked whether pregnancy, a risk factor for dry eye disease associated with both chronic, immune-mediated- and autoimmune etiologies, augments development of clusters of coordinately functioning cells (CCFC) that may be precursors to pathological lacrimal gland infiltrates. METHODS Lacrimal glands were from six virgin- and six term-pregnant rabbits of the same age and environmental exposure history. Seventy-two immune response-related gene transcripts were assayed by real time RT-PCR. Principal component (PC) analysis identified transcript signatures of CCFC contributing negative (⊖) or positive (⊕) PC loadings and determined gland PC projections, which reflect levels of CCFC development. RESULTS Three CCFC were of interest as potential precursors to pathological infiltrates. CCFC 1⊖ was suggestive of an ectopic lymphoid structure with resting T cells and B cells. CCFC 1⊕ was suggestive of an immune-mediated infiltrate with TH1 cells and mature, cytotoxic B cells. CCFC 2⊖ was suggestive of an ectopic lymphoid structure with activated T cells, mature B cells, germinal center, and plasmacytes. CCFC 4⊖ and CCFC 5⊖ also included plasmacytes. Pregnancy augmented CCFC 1⊖ in some glands; augmented CCFC 1⊕ in others; and augmented CCFC 2⊖, CCFC 4⊖, and CCFC 5⊖ different combinations. CONCLUSIONS Potential precursors of pathological infiltrates form in the lacrimal glands by the time of sexual maturity. Pregnancy augments lacrimal gland plasmacyte populations, and it can augment development of potential precursors to either chronic, immune-mediated infiltrates or autoimmune infiltrates of various phenotypes. Systemic and strictly local, probabilistic phenomena interact with pregnancy to determine which combinatorial phenotypes are favored.
