概括
高近视与视网膜和胸膜血管密度增加有关,而衰老会降低视网膜血管密度. 轴长显著影响近视进展中的胸腔层.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 血管生物学 血管生物学
背景情况:
- 近视是一种常见的折射误差,涉及眼睛结构的复杂变化.
- 了解近视的血管变化对于理解其病变发生至关重要.
研究的目的:
- 用扫描源光学连贯性断层扫描血管学 (SS-OCTA) 来调查年轻近视患者的斑点血管变化.
- 为了区分非高近视 (NHM) 和高近视 (HM) 组之间的血管特征.
- 阐明近视的轴长度,年龄和血管参数之间的关系.
主要方法:
- 对103名接受SS-OCTA的年轻成年人 (154只眼睛) 的回顾性分析.
- 分类为NHM (轴长<26.5mm) 和HM (轴长≥26.5mm) 组.
- 评估表面毛细管 (SCP),深层毛细管 (DCP),胆道毛细管 (CC) 密度,胆道沙特勒和哈勒层 (CSHL) 密度,状血管区域 (FAZ) 面积和状血管厚度 (SFCT).
- 多变量回归分析以确定年龄,球体等价值 (SE),轴长 (AL) 和SFCT对OCTA参数的影响.
主要成果:
- 与HM组相比,NHM组的SCP,DCP和CC密度明显较低.
- 在NHM组中,CSHL密度 (subfoveal和parafoveal temporal) 显著低于HM组.
- 随着近视的增加,SCP密度增加,随着年龄的增长而减少;随着年龄的增长,DCP密度下降.
- 随着轴长度的增加,CSHL密度增加.
结论:
- 年龄主要影响视网膜血管密度,而轴向长度显著影响胆层的萨特勒和哈勒层.
- 下和上的时间CSHL密度是监测近视进展的关键指标.
- 高近视可能存在补偿机制,以维持视觉功能.

01:25Glaucoma: Overview
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...
01:27Open 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.
