概括
使用密集的B扫描OCTA对周周毛囊毛细体积 (PPCV) 分布的定量分析对于预测糖尿病视网膜病变 (DR) 患者进行泛视网膜光凝和手术的结果非常有价值.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 糖尿病视网膜病变研究研究
背景情况:
- 糖尿病视网膜病变 (DR) 是导致视力丧失的主要原因.
- 周毛细血管体积 (PPCV) 分布的定量分析可以提供预后见解.
- 密度B扫描光学连贯断层扫描血管学 (DB OCTA) 能够进行详细的微血管评估.
研究的目的:
- 探索在正常和DR眼中定量分析PPCV分布的价值.
- 评估PPCV分布与年龄,位置,DR严重程度和治疗结果的相关性.
主要方法:
- 具有前性后续的横截面观测研究.
- 招募了101名健康受试者和140名DR患者.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
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...
