概括
在非动脉炎性缺血性视觉神经病变 (NAION) 中,质细胞内状层 (GCIPL) 厚度与视觉功能相关. 较薄的GCIPL和视野平均偏差减少预测视力敏度结果更差.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
背景情况:
- 非动脉炎性缺血性视神经病变 (NAION) 是视神经损伤的主要原因.
- 了解NAION中结构和功能变化之间的关系对于患者管理至关重要.
研究的目的:
- 研究单边NAION患者的结构和功能参数之间的相关性.
- 在急性NAION中确定视神经功能和视觉预后的关键指标.
主要方法:
- 对29名NAION患者进行了回顾性研究.
- 综合评估包括视力敏度,光学连贯断层扫描 (OCT),OCT血管造影 (OCTA),视野 (VF),视觉唤起潜能 (VEP),电网膜扫描 (ERG) 和多焦点ERG (mf-ERG).
- 在提交后三个月的后续评估.
主要成果:
- 急性NAION显示RNFL厚度增加,GCIPL厚度减少.
- 观察到减少了VF平均偏差 (MD) 和VEP P100振幅,延长了延迟时间.
- 在GCIPL参数和电生理学测量 (VEP,mf-ERG) 之间发现了显著的相关性.
- 基线GCIPL厚度,VF MD和VEP P100幅度与3个月后的视力敏度相关.
结论:
- 视网膜质细胞层 (GCIPL) 厚度是急性NAION视神经功能的一个有价值的客观指标.
- 降低VEP振幅和mf-ERG响应密度与GCIPL厚度相关.
- 基线视野,VEP和GCIPL厚度预测了3个月后的视力敏度.

01:25Glaucoma: Overview
478
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...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
