概括

孕前的严重程度会影响眼睛的微血管结构. 严重的孕前显示较低的深层毛细管血管密度 (DCPVD) 和辐射周毛细管毛细管血管密度 (RPCVD),分娩后恢复较慢.

科学领域:

眼科医生眼科眼科
周围生理学周围生理学
血管生物学血管生物学

背景情况:

孕前是一种严重的妊娠并发症,其特点是高血压.
它对微血管系统,特别是视网膜的系统性影响尚未完全理解.

研究的目的:

为了前性地评估产前症严重程度对胆管甲状腺微血管的影响.
使用光学连贯断层扫描血管学 (OCT-A) 进行详细的微血管评估.

主要方法:

66名患者被分为轻度和重度妊娠前组.
在分娩前,分娩后2天和分娩后6周进行了OCT-A成像.
胆道管微血管密度参数进行了比较,并与血压相关.

主要成果:

深毛细管血管密度 (DCPVD) 和辐射周毛细管血管密度 (RPCVD) 在分娩后增加.
与轻度病例相比,严重的孕前患者在分娩前和产后早期的DCPVD和RPCVD显著降低.
DCPVD和RPCVD与全身血压有显著的负相关性.

结论:

孕前症的严重程度显著影响胆管小血管密度.
DCPVD和RPCVD与血压相反相关.
虽然视网膜微血管改善了分娩后,但严重的孕前会导致更长时间的血管功能障碍.

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...
