概括
宫内角膜环段 (ICRS) 最初改善了形角膜患者的视力,但长期随访显示,几年后,未经纠正的视力敏度下降. 这表明ICRS可能不会提供永久的视力稳定性.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 视觉科学科学 视觉科学
背景情况:
- 角膜是一种渐进的角膜疾病,导致突起和视力受损.
- 宫内角膜环段 (ICRS) 用于治疗角质,目的是稳定或改善视力,并推迟先进的手术干预.
- 对于ICRS在角质结核病管理中的长期疗效数据仍然有限.
研究的目的:
- 评估角膜内环段 (ICRS) 植入在患有角膜的患者中的长期结果.
- 提供延长后续分析,平均后续时间约为5年,延长至12.5年.
主要方法:
- 招募了2008年至2013年期间接受ICRS植入的患者队列.
- 收集的数据包括手术前的基线和最新的随访数据:视敏度,折射,裂灯检查和角膜断层扫描.
- 从植入前到最新的随访,对最佳校正视敏度和最大角膜度的变化进行了比较.
主要成果:
- 该研究包括来自53名患者的68只眼睛,平均随访时间为53.87个月 (长达153个月).
- 在随访期间观察到纠正/不纠正视力敏度,角质量测量和折射率的显著改善.
- 在手术后的时间和未经纠正的视力敏度和平均角质量测量的变化之间发现了负相关性. 随访>100周的许多患者的视力敏度与基线相同或比基线差.
结论:
- ICRS植入可以导致初始视力敏度的改善在角患者.
- 在植入后的最初几年后,观察到视力敏度的随后下降.
- 长期结果表明,ICRS的视觉效益可能不会无限期持续.

Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
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...
