概括
与非糖尿病患者相比,糖尿病患者显示角膜内皮细胞密度和六角性减少. 糖尿病持续时间较长和血糖控制不佳,以HbA1c表示,加剧了这些角膜变化.
科学领域:
- 眼科医生 眼科 眼科
- 糖尿病学 糖尿病学
- 角质科学 角质科学
背景情况:
- 糖尿病 (DM) 与各种眼部并发症有关,包括对角膜健康的潜在影响.
- 角膜形态和内皮功能可能会受到糖尿病等全身性疾病的影响.
研究的目的:
- 为了比较2型糖尿病患者和年龄匹配的非糖尿病对照之间的角膜参数.
- 调查角膜参数与糖尿病持续时间,HbA1c水平和糖尿病视网膜病变 (DR) 严重程度之间的相关性.
主要方法:
- 一项比较研究包括100名2型糖尿病患者和100名年龄性别匹配的非糖尿病对照.
- 镜像显微镜被用于评估中枢角膜厚度 (CCT),内皮细胞密度 (ECD),变异系数 (CoV),六角性 (6A) 和平均细胞面积.

Diabetes: Symptoms, Diagnosis, and Complications
521
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...

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...
