概括

状镜片 (SL) 的磨损显著降低了状患者的眼和镜片库中的活性氧物种 (ROS) 水平. 这一发现突显了SLs在管理与这种角膜疾病相关的氧化应激方面的潜力.

科学领域:

眼科医生眼科眼科
角质细胞疾病角质细胞疾病
眼睛表面分析眼睛表面分析

背景情况:

氧化应激和高反应性氧物种 (ROS) 与角膜病理,如角膜炎 (KC) 有关.
了解眼镜 (SL) 磨损对这些机制的影响对于优化癌症患者管理至关重要.

研究的目的:

为了评估在眼镜佩戴期间眼睛中ROS水平的变化.
评估膜透镜在减少皮患者氧化应激的有效性.

主要方法:

眼样本 (T0) 和膜透镜液储库 (SLFR) 样本从26个形眼睛在基线,第1天和1个月收集.
使用计量量度量化了ROS水平.
视觉敏度和眼睛表面疾病指数 (OSDI) 也被评估.

主要成果:

眼中的ROS水平 (T0) 在SL磨损6小时后显著降低 (p < 0.001) 在1个月内.
与第一天相比,SLFR中的ROS水平在1个月的磨损后下降 (p = 0.007).
观察到视敏度和OSDI得分的显著改善 (p < 0.001).

结论:

结膜镜片的佩戴有效地降低了SL液体储存库中的ROS水平,并减少了形患者的眼.
减少ROS可能与角病原发生有关,需要进一步调查.
SL磨损证明了作为治疗方法来管理形的氧化应激的潜力.

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
