概括
增加的冠状腺 stromal 体积 (CSV) 与神经血管与年龄相关的黄斑变性 (nAMD) 相关,即使在高风险的眼睛. 这一发现表明CSV可能是nAMD发展的生物标志物.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 视网膜疾病 视网膜疾病
背景情况:
- 神经血管与年龄相关的黄斑变性 (nAMD) 是导致视力丧失的主要原因.
- 了解胸膜中的结构和血管变化对于nAMD管理至关重要.
- 扫描源光学连贯性断层扫描血管造影 (SS-OCTA) 提供了胸膜的详细成像.
研究的目的:
- 使用SS-OCTA,在nAMD的不同阶段对定量胆道指标进行表征.
- 确定与nAMD相关的结构和血管协会.
- 在健康的对照群,同眼睛和受nAMD影响的眼睛中评估胸腔体积,流动密度和血管性.
主要方法:
- 一项横截面研究涉及230只健康的对照眼睛,110只不受影响的同伴眼睛和104只受nAMD影响的眼睛.
- 使用SS-OCTA量化斑点胆囊细胞流动密度 (CCFD),胆囊体积 (CV),胆囊体积 (CSV) 和胆囊血管体积 (CVV).
- 在对照,同学和nAMD眼睛之间比较定量指标,以确定显著的差异和关联.
主要成果:
- 中位数CCFD显示对照和同眼之间以及同眼和nAMD眼之间存在显著差异.
- 与对照人群相比,同眼和nAMD眼的中位数CSV显著高于对照人群.
- 在nAMD眼中发现了CSV和CCFD之间的反向相关性,特别是在特定的象限.
结论:
- 增加的CSV与nAMD的存在有关,包括高风险的眼睛.
- CSV和CCFD之间的逆相关性表明,nAMD中肌体扩张和微血管妥协之间的相互作用.
- 升高的CSV可以作为nAMD发展的潜在生物标志物,需要进一步的纵向研究.

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...
