概括
分支视网膜静脉阻塞 (BRVO) 导致黄斑,通常呈现为囊状黄斑. 光学连贯断层扫描 (OCT) 对于检测微妙的变化至关重要,如血清性视网膜脱落和光感受器干扰在BRVO患者.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜血管疾病 视网膜血管疾病
- 医疗成像医学成像
背景情况:
- 分支视网膜静脉封闭 (BRVO) 是老年人患有常见的视网膜血管疾病,仅次于糖尿病视网膜病变.
- 了解BRVO中黄斑的形态特征对于患者管理至关重要.
研究的目的:
- 阐明与分支视网膜静脉封闭 (BRVO) 相关的斑点的多样性形态模式.
- 评估光学连贯断层扫描 (OCT) 在表征这些模式中的实用性.
主要方法:
- 进行了一项描述性,横截面研究,涉及84名被诊断患有BRVO相关黄斑胀的84名患者的84只眼睛.
- 患者从2017年7月到2018年7月招募,诊断通过光学连贯断层扫描 (OCT) 得到证实.
主要成果:
- 观察到的占主导地位的形态模式是囊性黄斑胀 (80.95%),其次是包括血清性视网膜脱落和扩散性黄斑胀在内的变异.
- 在35.71%的眼睛中,观察到内部和外部段 (IS/OS) 交叉点的破坏.
- 患者的平均年龄约为68岁,男性略有占主导地位.
结论:
- 光学连贯断层扫描 (OCT) 是一种安全的,非侵入性的成像方法,对于识别BRVO中微妙的斑点变化至关重要.
- OCT有助于检测血清性视网膜脱落和光受体破坏,否则可能会错过.
- OCT量化视网膜厚度变化的能力有助于预测BRVO诱导黄斑的患者的视觉结果.

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:19Imaging 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...

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...
