Although prevalent, distinct clinical biomarkers associated with the impairment of the lacrimal (LG) and meibomian glands (MG) that exacerbate the progression of DES are still largely lacking. This study was conducted to identify potential DES markers for precise clinical diagnosis.</p>\u0000 \u0000 <p><b>Methods:</b> Subjects underwent a battery of clinical examinations including the basic secretory test <i>via</i> Schirmer I to evaluate the functional impairment of the LG that leads to aqueous-deficient DES (DRYaq). Meanwhile, tear break-up time (TBUT) test was used to evaluate the impairment status of the MG, which leads to evaporative DES (DRYlip). Next, the tear samples (N = 307) were analyzed individually employing mass spectrometry-based proteomics, followed by in-depth statistical and bioinformatics analyses.</p>\u0000 \u0000 <p><b>Results:</b> A total of 47 proteins, largely secreted by the LG and annotated to antibacterial response (<i>p</i> = 5.0 × 10<sup>-9</sup>) were found to be significantly (<i>p</i> < 0.01) decreased in abundance with the progression of DRYaq, namely LTF (<i>r</i> = -0.79), PROL1 (<i>r</i> = -0.64) and AZGP1 (<i>r</i> = -0.58). On the contrary, as many as 360 proteins were found to be significantly increased in abundance with the progression of DRYaq, namely SFN (<i>r</i> = +0.68), ORM2 (<i>r</i> = +0.67) and TXN (<i>r</i> = +0.66). These proteins are annotated to various biological functions, especially inflammatory response (<i>p</i> = 3.0 × 10<sup>-17</sup>), apoptosis (<i>p</i> = 2.1 × 10<sup>-29</sup>) and synthesis of reactive oxygen species (<i>p</i> = 3.7 × 10<sup>-29</sup>).

However, measurement techniques for the assessment of retinal oxygen extraction are limited because most of them are based on time-consuming and custom-built devices. In the present pilot study, we assessed retinal oxygen extraction during systemic hypoxia with a combination of two commercially available devices: Laser-Speckle Flowgraphy (LSFG) and retinal oximetry.</p>\u0000 \u0000 <p><b>Methods:</b> Retinal blood flow and retinal oxygen saturation were measured in each vessel around the optic nerve head at the same position. Arterial and venous oxygen content was estimated from the measured retinal oxygen saturation parameters and the difference between these two parameters was calculated (cO<sub>2</sub>,<sub>DIFF</sub>). By using mean vessel flow rate (MV) for retinal blood flow and cO<sub>2</sub>,<sub>DIFF</sub>, retinal oxygen extraction was determined.

The rtx1 was configured for a 20 second, 15Hz, and 4 μW.cm^(-2) flicker stimulation over a 29x20 degrees area of the imaged eye fundus. Acquisitions for each subject were repeated 159+/-17 (m+/-sd) days later.</p>\u0000 \u0000 <p>The lumen of retinal arterioles within the macular region was determined using custom-developed software for the automatic segmentation of lumen-wall interfaces. An experienced technician visually assessed all segmentations to reject subpar results. Lumen diameters were calculated from the distance between the lumen-wall interfaces as measured perpendicular to the vessel axis along a vessel segment. NVC responses were calculated per eye as the relative difference (%) of the lumen diameter after stimulation to the respective baseline.</p>\u0000 \u0000 <p><b>Results:</b> A total of 22 out of 156 images (14%) were rejected and excluded from further analysis. NVC responses ranged from 0.21% to 8.28% (3.36+/-2.75 % (m+/-sd)) for the first visit and from -0.24% to 9.13% (3.03+/-2.54 %) for the follow-up. Response differences between time points ranged from -6.15% (8.28% to 2.13%) to 4.21% (0.98% to 5.19%), with an average (sd) of 0.34(3.03) % for the group. A paired sample Wilcoxon test between time points is not statistically significant (<i>p</i> = 0.650), supporting that the responses are consistent between time points.</p>\u0000 \u0000 <p><b>Conclusions:</b> The obtained results show a consistent NVC response for a 5-month interval.</p>\u0000 </section>\u0000 </div>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":"103 S284","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1111/aos.17276","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
