概括
带有血管条纹 (AS) 的伪神经弹性体 (PXE) 中的新血管化 (NV) 通常是1型NV,这可能导致视力丧失. 动脉瘤1型NV显著增加排泄风险,需要密切监测.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 遗传学 是一个遗传学.
背景情况:
- 伪虫弹性 (Pseudoxanthoma elasticum,简称PXE) 是一种罕见的遗传疾病,影响弹性组织.
- 血管条纹 (AS) 是PXE的常见眼部表现,增加了新血管化的风险.
- 在AS中,新血管化 (NV) 可以导致显著的视力损伤.
研究的目的:
- 为了描述新血管化 (NV),特别是动脉瘤类型1 NV,在患有血管条纹 (AS) 的患者中,这是 Pseudoxanthoma elasticum (PXE) 的次要原因.
- 确定与PXE相关的AS中不同类型的NV相关的患病率和视觉结果.
- 根据多式成像检测结果,引入AS的临床分类.
主要方法:
- 追溯纵向队列研究85名患者 (168只眼睛) 的AS次要的PXE.
- 使用多式成像,包括 fundus 摄影,自光,氨酸绿色血管造影,OCT 和OCT血管造影.
- 收集了关于1型视力障碍的患病率,视力敏度 (VA) 和排泄风险的数据.
主要成果:
- 1型NV是普遍存在的 (76%的眼睛),通常起源于视盘附近,延伸到斑点.
- 在1型NV (57%的眼睛) 中,动脉扩张显著增加了排泄风险 (HR=3.86,P=0.02).
- 排泄性1型NV导致VA显著恶化 (P=0.02),而2型NV与较差的结果和黄斑缩有关.
结论:
- 1型NV是与PXE相关的AS中占主导地位的形式,可以导致明显的视力损伤.
- 动脉瘤1型NV具有很高的排泄风险,需要谨慎监测.
- 为AS阶段制定了一个新的临床分类,从没有NV到高级NV.

Mechanism of Angiogenesis
5.4K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Glaucoma: Overview
530
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...
