概括

糖尿病视网膜病变 (DR) 患者表现出视网膜敏感度下降和视网膜内层厚度下降,特别是在质细胞层中,即使没有糖尿病黄斑 (DME). 这表明,在2型糖尿病 (DM2) 中,神经纤维层稀释之前,早期的质细胞损失是神经纤维层稀释.

科学领域:

眼科医生眼科眼科
糖尿病学糖尿病学
医疗成像医学成像

背景情况:

糖尿病视网膜病变 (DR) 的流行率不断上升,需要早期诊断生物标志物.
了解2型糖尿病 (DM2) 中的视网膜结构和功能变化对于疾病管理至关重要.

研究的目的:

分析2型DM2中度DR患者的视网膜总 (RT) 和内视网膜层 (IRL) 厚度.
为了将这些视网膜测量与视网膜灵敏度相关联,使用扫描源OCT (SS-OCT) 和微波测量.
确定早期DR检测和进展评估的潜在生物标志物.

主要方法:

利用SS-OCT量化54名DM2患者 (中度DR,没有DME) 和73名对照患者的斑点视网膜厚度.
使用斑点完整性评估装置 (MAIA) 微波测量测量了视网膜敏感性.
与视敏度和脂质谱相关联的视网膜厚度测量 (LDL-C,HDL-C).

主要成果:

与对照组相比,DM2患者的视力敏度较低,视网膜 (RT) 总厚度较厚.
在DM2患者的外鼻区域观察到明显减少的视网膜神经纤维层 (RNFL) 厚度.
在中部和内鼻区域的RNFL厚度和视网膜敏感性之间发现了负相关性,表明功能下降.

结论:

视网膜敏感性和黄斑RNFL厚度降低在DM2患者中度DR,即使没有DME.
质细胞和内状层 (GCL+) 的稀薄可能表明RNFL变化之前的质细胞损失.
这些发现支持基于疾病阶段和进展的DR评估的个性化方法.

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
