概括
这项研究揭示了在接受抗VEGF治疗的湿时与年龄相关的黄斑变性 (AMD) 患者中,子皮质神经血管膜如何演变的明显模式. 这些模式与特定的新血管膜类型相关,并随着时间的推移影响视觉敏度.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 医疗成像医学成像
背景情况:
- 与年龄相关的斑点退化 (AMD) 是导致视力丧失的主要原因.
- 长期的抗血管内皮生长因子 (抗VEGF) 疗法是管理外泄性AMD的标准.
- 了解胆道新血管化 (CNV) 的演变及其对治疗结果的影响至关重要.
研究的目的:
- 分析在排泄性nAMD中不同HRM演变模式的频率.
- 研究HRM进化模式与新血管膜 (MNV) 类型之间的相关性.
- 评估HRM模式与长期抗VEGF治疗下的形态和功能变化的关联.
主要方法:
- 对94名nAMD患者143只眼睛的光学连贯性断层扫描 (OCT) 体积扫描进行了回顾性分析.
- 将人力资源管理的演变分为四种不同的模式 (1-4).
- 对HRM模式与MNV类型,黄斑缩和最佳校正视力敏度 (BCVA) 的相关性分析.
主要成果:
- 发现了四种HRM演变模式,其频率不同 (模式1: 40.6%,模式2: 23.1%,模式3: 27.3%,模式4: 9.1%).
- 人力资源管理模式与MNV类型有显著的相关性 (p=0.02),特别是1型MNV和2型MNV的1型模式和3型模式.
- 图形4的特征是没有边界重塑的持续的子内HRM,与黄斑缩有关 (p<0.0001) 并在所有时间点降低了BCVA.
结论:
- 在接受抗VEGF治疗的排泄性nAMD患者中存在明显的HRM进化模式.
- 这些模式与特定的MNV类型相关,可以预测形态和功能结果.
- 人力资源管理模式可以作为长期视觉功能的预后指标在nAMD.

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

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...
