- 糖尿病视网膜病变研究研究
背景情况:
- 糖尿病视网膜疾病 (DRD) 影响全球数百万人,往往导致视力受损.
- 视网膜内层 (DRIL) 的失调是DRD严重程度的关键指标.
- 准确的DRIL结构特征对于了解其对视觉功能的影响至关重要.
研究的目的:
- 评估增强轴分辨率光学连贯性断层扫描 (OCT) 是否改善了糖尿病患者DRIL的结构特征.
- 调查通过增强的OCT检测到的DRIL与功能和血管变化之间的关联.
主要方法:
- 未来的横截面研究涉及55名糖尿病患者 (27名DRIL患者,28名没有DRIL患者).
- 使用了传统的光谱域OCT (SD-OCT),高分辨率 (High-Res) OCT,OCT血管学 (OCTA) 和微观测量.
- 在SD-OCT和高分辨率OCT之间比较了DRIL面积测量.
主要成果:
- 高分辨率OCT检测到与SD-OCT相比显著较小的DRIL区域 (0.3比1.3毫米2).
- 在对DRSS进行调整后,OCT血管造影显示了DRIL和非DRIL眼睛之间血管密度和FAZ循环的持续差异,即使对DRSS进行调整.
- 视网膜敏感性逐步从未受到影响的视网膜逐步降低到通过两种OCT模式或仅通过SD-OCT检测到的DRIL区域.

01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

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...
