概括
与其他眼睛相比,异位双眼眼的视网膜微血管密度降低. 这种血管密度的降低与眼的严重程度相关,表明其作为生物标志物的潜力.
科学领域:
- 眼科 眼科
- 视网膜成像
- 神经科学
背景情况:
- 不同度的视会影响视觉发育.
- 视网膜微血管结构的变化可能是眼的基础.
- 光学连贯断层扫描 (OCTA) 允许详细的视网膜成像.
研究的目的:
- 通过使用OCTA在异度双眼眼中的视网膜微血管结构与同眼相比较.
- 评估表面和深层毛细管血管的密度.
- 为了评估体无血管区 (FAZ) 的参数.
主要方法:
- 在40名患有单侧异质眼的儿童中进行了比较观察研究.
- 用OCTA成像测量表面和深层血管密度.
- 对FAZ面积,周长度和非循环度指数的分析.
主要成果:
- 眼患者的表面和深层血管密度显著降低 (P < 0. 05).
- 在两层中,严重的眼显示出更明显的眼差异 (P = 0.04,P = 0.02).
- 血管密度与最佳视力度有负相关性.
结论:
- 在异位眼的双眼眼中,视网膜血管密度降低.
- 表面和深层毛细血管的血管密度是眼严重程度和进展的潜在生物标志物.

Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
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...
