Summary: The study found that tear evaporation rate (TER) and tear break-up time do not significantly vary throughout the day or on different days in healthy individuals when humidity and temperature are constant. However, certain tear molecule levels show inter- and intra-day variability and have a moderate correlation with TER diurnal variation.

Summary: This study described the glycoproteomic profile of roadside hawk and caiman tears, showing N-type modifications for all identified glycopeptides. The glycoproteins were found to be extracellular, with endopeptidase inhibitor activity as the main molecular function for both species. These differences compared to human tears may be linked to adaptive processes and could be key for future disease biomarker research.

Summary: The tear film lipid layer (TFLL) plays a crucial role in maintaining high-quality vision, protecting the cornea, and promoting wound healing. Plasma rich in growth factor (PRGF) eye drops have emerged as a new treatment for aqueous deficient dry eye. This study compared the lipid profiles of PRGF eye drops with tears and found that the lipids in PRGF eye drops could be used as a supplement for altered tear lipid composition.

Summary: This study aimed to investigate the change in dynamic optical quality in dry eye patients after the use of artificial tears. The study found that optical quality indices were significantly higher in dry eye patients compared to the control group, but decreased significantly after 5 minutes of artificial tear instillation in severe dry eye patients. There were no significant differences in optical quality parameters among the three groups after 30 minutes.

Summary: This study investigated the behavior of telomerase reverse transcriptase (hTERT) in the tears of healthy individuals wearing contact lenses. The results showed that the levels of hTERT increased after contact lens wear, but this change was small compared to the impact of overnight eye closure. In addition, the inflammatory mediators IL-6 and TNF-alpha showed minimal response at the same time points.

Summary: By constructing normalized ocular surface temperature (NOST) models for different tear film characteristics, it is possible to differentiate tear film types and potentially use them for dry-eye screening. The study found that in dry-eye screening, the NOST order was normal > short-BUT > short BUT with SPK.

Summary: Contact lens materials have undergone significant changes in the past 20 years with the introduction of silicone hydrogel materials. However, research is still needed to improve comfort, as the association between contact lens wettability and comfort is not clear. The interactions between lens materials, tear film, and disinfection solution play an important role in biocompatibility, but whether this can be altered to improve comfort remains debatable.

Summary: The purpose of this study was to analyze inflammation-and pain-related molecules in tears of patients suffering from chronic ocular pain associated with dry eye and/or a previous corneal refractive surgery. The study found that IL-10 and SP levels in tears were increased in patients with a history of corneal refractive surgery. IL-9 levels were associated with chronic ocular pain. These findings suggest that tear cytokines and neuromodulators could serve as biomarkers for chronic ocular pain, leading to improved therapeutic and disease management decisions.

Summary: The purpose of this study was to analyze inflammation- and pain-related molecules in tears of patients suffering from chronic ocular pain associated with dry eye and/or a previous corneal refractive surgery. The results showed that IL-9 tear levels were increased in patients with chronic ocular pain, IL-10, SP, MIP-1 alpha/CCL3, IL-2, and IFN-gamma were associated with previous surgery, and IL-8/CXCL8, MIP-1 alpha/CCL3, IL-2, and IFN-gamma were associated with DE-related inflammation. Higher NGF levels were related to chronic ocular pain and DE in patients with previous surgery. These findings are important for understanding biomarkers of chronic ocular pain and making better therapeutic and disease management decisions.

Summary: Glaucoma is a leading cause of irreversible blindness worldwide, and the measurement of intraocular pressure is crucial for its diagnosis and management. The importance of corneal biomechanical properties in intraocular pressure measurement is increasingly recognized. The development of new instruments has the potential to improve the accuracy and convenience of intraocular pressure measurement.

Summary: The use of contact lenses can lead to an increase in the concentration of inflammatory molecules in tears. This study found significant changes in IL-1 beta, IL-6, IL-8, IL-17, LTB4, and MMP-9. Rigid gas permeable lenses were found to cause a stronger sub-clinical inflammatory response compared to soft contact lenses, with IL-8, MMP-9, and EGF playing important roles. Reusable lenses worn continuously or on a daily modality were more likely to raise the expression of biomarkers compared to daily disposables.

Summary: Acanthamoeba keratitis is a widespread infection caused by a unicellular protozoan that mainly affects contact lens wearers and is linked to corneal trauma as well. It is essential to deepen the understanding of risk factors, focus on prevention strategies, and enhance the efficacy of disinfection systems to minimize the risk of infection. Additionally, there is a need for the development of effective diagnostic methods and treatments for this type of corneal infection in the near future.
