概括
非动脉炎前面缺血性视觉神经病变 (NAION) 涉及视觉盘的结构变化,特别是增加了前层组织厚度 (PLTT),这是NAION易感性的关键因素.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
- 医疗成像医学成像
背景情况:
- 非动脉炎前部缺血性视神经病变 (NAION) 是一种常见的视神经病变,影响视盘.
- 在NAION中光盘的结构特征尚不清楚.
研究的目的:
- 为了确定与NAION相关的特定光盘结构特征.
- 调查前层组织厚度 (PLTT) 在NAION易感性中的作用.
主要方法:
- 横截面研究比较NAION受影响的眼睛,不受影响的同眼睛和正常的眼睛.
- 使用扫描源光学连贯断层扫描血管学 (SS-OCTA) 进行测量.
- 测量了圆皮状视网膜神经纤维层 (cRNFL) 厚度,薄膜深度 (LCD) 和前层组织厚度 (PLTT).
- 引入了一个新参数:视网膜神经纤维层密度 (RNFLD).
主要成果:
- 受NAION影响的眼睛和同眼睛显示PLTT明显比正常眼睛更厚 (p < 0.001).
- 与正常的眼睛相比,NAION眼睛具有更薄的周附视网膜神经纤维层 (pRNFL) (p < 0.001),而其他眼睛则具有更厚的cRNFL (p < 0.001).
- 在NAION-fellow眼睛中观察到较高的RNFLD (p < 0.01).
- PLTT与NAION易感性 (OR = 1.017,p < 0.001) 独立相关,具有高诊断准确性 (AUC = 0.905).
结论:
- 受影响的和不受影响的NAION眼睛都显示了光盘中非神经纤维组件的增加.
- 这些组成部分可能代表质组织或原始玻璃体残留物.
- 增加的PLTT是发展NAION的一个独立风险因素.

Glaucoma: Overview
1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment
1.1K
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.
