概括

在青少年近视症中,视网膜血管密度保持稳定,但胆道血管密度随近视症的进展而增加,这与减少底胆道血管厚度有关. 这项研究使用扫描源光学一致性断层扫描 (SS-OCT) 来分析这些血管变化.

科学领域:

眼科医生眼科眼科
视网膜成像视网膜成像
血管生物学血管生物学

背景情况:

近视是一种日益严重的公共卫生问题,特别是在儿童中.
了解近视眼中的血管变化对于管理这种情况至关重要.
青少年近视症涉及视网膜和胸膜的复杂病理生理变化.

研究的目的:

为了研究青少年近视症中黄斑视网膜和胆囊细胞的血管特征变化.
用扫描源光学一致性断层扫描 (SS-OCT) 来分析与近视严重程度相关的胸腔血管化.
为了进一步阐明儿童近视眼的病理生理学特征.

主要方法:

对103名年轻患者 (6-17岁) 进行了回顾性病例对照研究,共198只眼睛.
根据球体功率将其分类为凝视,低,中等和高近视群.
使用SS-OCT测量表面毛细管 (SCP) 密度,胆管 (CC) 密度,胆管血管 (CV) 密度和亚管胆管厚度 (SFCT).
多变量回归分析以确定与血管指标相关的因素.

主要成果:

与低近视相比,中度近视显示在形形区域的SCP密度明显较低.
高度近视的眼睛表现出明显更高的亚叶胆管血管 (CV) 密度,而不是视眼睛.
较薄的亚叶冠状体厚度与斑点区域冠状体血管密度增加有关.

结论:

青少年近视的进展与稳定的视网膜表面血管和胆道毛细血管密度有关.
状血管密度在膜下逐渐随着近视的进展而增加.
在近视眼中,状血管密度变化的主要决定因素是状血管下状血管厚度的变化.

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview

Glaucoma: 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...

Angle Closure Glaucoma: Treatment

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...
