The secretory activities of meibomian glands are regulated by the autonomic nervous system. The change in density and activity of autonomic nerves in meibomian glands during menopause play an important role in the pathogenesis of dry eye. In view of this, we established a dry eye rat model by removing the bilateral ovaries. We used neuropeptide Y and vasoactive intestinal polypeptide as markers of autonomic neurotransmitters. Our results showed that the concentration of estradiol in serum significantly decreased, the density of neuropeptide Y immunoreactivity in nerve fibers significantly increased, the density of vasoactive intestinal polypeptide immunoreactivity in nerve fibers significantly decreased, and the ratio of vasoactive intestinal polypeptide/neuropeptide Y positive staining significantly decreased. These results suggest that a decrease in ovary activity may lead to autonomic nervous system dysfunction, thereby affecting the secretory activity of the meibomian gland, which participates in sexual hormone imbalance-induced dry eye.

Background: Adverse events (AE) in dupilumab induced ocular surface diseases (DIOSD) have raised concerns regarding its safety. The objective of this study was to evaluate DIOSD by employing database analysis and clinical case review, along with mechanism analysis.
Research Design And Methods: Database AE data were extracted from FAERS from 2017 Quarter 1 (Q1) to 2023 Q1.

Aims: To understand current clinical management of dry eye disease (DED), based on its perceived severity and subtype by practitioners across the world.
Methods: The content of the anonymous survey was chosen to reflect the DED management strategies reported by the Tear Film and Ocular Surface Society (TFOS) 2 Dry Eye Workshop (DEWS II). Questions were designed to ascertain practitioner treatment choice, depending on the subtype and severity of DED.

Dry Eye Disease (DED) is a common condition worldwide, with smoking being recognized as a possible aggravating factor. Although observational studies have indicated a potential correlation, the findings have been inconclusive. In the study, Mendelian randomization (MR) analysis is used to investigate this potential causal relationship.

Objective: Blood component therapy has shown promising potential as an emerging treatment for dry eye disease; however, it remains unclear which specific blood component is the most effective. This study aims to compare the efficacy of different blood components in the treatment of dry eye disease through a network meta-analysis, with the goal of providing the latest and most reliable evidence for clinical practice.
Methods: We conducted a systematic search of the PubMed, Web of Science, Cochrane, Embase, and Scopus databases, with the search concluding on June 1, 2024.

Background: Contact lens discomfort (CLD) is a common problem for CL wearers, and patients with CLD often have changes in meibomian gland function and structure. In a Phase 2 trial AZR-MD-001 0.5% (AZR) ophthalmic ointment improved meibomian gland dysfunction (MGD) in non-lens wearers.
