概括
健康个体的水平眼动对光学连贯性断层扫描血管学 (OCTA) 数据的影响最小. 在左眼的上半球中发现了轻微的变化,这表明视线转移的影响有限.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 神经科学是一个神经科学.
背景情况:
- 水平眼动可以机械地影响视神经.
- 光学连贯断层扫描血管造影 (OCTA) 是研究这些效应的最新技术.
- 关于OCTA和眼动的先前研究是有限的.
研究的目的:
- 为了研究健康个体在水平眼动 (初级目光,绑架,引进) 期间OCTA数据的变化.
- 评估凝视位置对辐射周毛细血管密度 (RPCD) 参数的影响.
主要方法:
- 一项涉及30名健康志愿者 (15-73岁) 的前性研究.
- 使用OCTA (Angio Disc QuickVue) 检查了辐射周毛细血管密度 (RPCD) 的参数.
- 测量是在主要的目光,绑架和引进位置.
主要成果:
- 只有在左眼的上半场 (P=0.032) 观察到统计学上显著的差异.
- 在上半球中,所有血管的血管密度 (AV) 在引过程中都呈相对下降.

Accessory Structures of the Eye
1.5K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Glaucoma: Overview
508
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
393
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.
