概括

在近视时,视网膜表面积增加会减少视网膜血管密度. 冠状腺以增加的血管性补偿,可能为视网膜内部提供氧气.

科学领域:

眼科眼科
视网膜成像
血管生物学

背景情况:

近视与眼睛的解剖学变化有关.
了解近视的血管适应对于管理相关病态至关重要.

研究的目的:

调查视网膜和胆道血管的适应性变化与视网膜表面积的增加有关.

主要方法:

使用了广场光学连贯断层扫描和增强深度成像 (EDI) - OCT.
视网膜血管密度和胆道血管密度指数得到量化.
分析了近视,视网膜血管密度和胆道血管指数之间的相关性.

主要成果:

轴近视的增加与视网膜血管密度有负相关性 (r2 = 0.35, P < 0.001).
轴近视的增加与胸腔血管度指数呈正相关性 (r2 = 0.31,P < 0.001).

结论:

近视的眼睛表现出视网膜血管覆盖率下降,视网膜表面积增加.
在高近视症中,胆道血管度指数增加,可能弥补了视网膜血管供应的减少.
这些适应性变化可以通过促进胆道血管的氧气扩散来支持视网膜内部的神经元.

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...
