概括
通过OCTA检测到的视神经头部的微血管流失 (MvD) 与绿眼病患者的血流减少和视力恶化有关. 这一发现可能有助于确定青光眼的进展.
科学领域:
- 眼科医生 眼科 眼科
- 血管生物学 血管生物学
- 医疗成像医学成像
背景情况:
- 玻璃眼是全球不可逆转失明的主要原因,由视神经病变驱动.
- 血管功能障碍,特别是视神经头部输液受损,越来越多地与玻璃眼有关.
- 光学连贯断层扫描血管学 (OCTA) 允许微血管系统的非侵入性可视化,识别周周微血管系统脱落 (MvD) 作为潜在的玻璃眼瘤标志物.
研究的目的:
- 为了研究周周毛囊微血管性脱落 (MvD) 和初级开角青光眼 (OAG) 中的眼睛参数之间的关联.
- 评估MvD作为一种潜在的结构标志物,对玻璃眼视野损伤.
主要方法:
- 一项横截面病例控制研究,涉及41名OAG患者和46名健康对照.
- 进行了全面的眼科评估和OCTA成像.
- 测量包括周周血管密度 (pVD),流量指数 (pFI),胸膜厚度 (PCT),β区域周周血管缩 (β-PPA) 和MvD检测.
主要成果:
- 青光眼患者的pVD,pFI,PCT和胆道血管指数明显低于对照组.
- 在10个青光眼中发现了MvD,与较大的β-PPA,减少胆道血管性和更差的视野平均偏差 (MD) 相相关.
- 对于视野缺陷,MvD表现出良好的辨别能力 (AUC = 0.77).
结论:
- 经OCTA检测到的周周细胞MvD与冠状血管性降低和玻璃眼中β-PPA增加有关.
- MvD与更大的视野恶化有关,这表明它有可能成为青光眼进展的结构标志物.

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...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
