概括
研究人员在自闭症谱系障碍 (ASD) 的儿童中发现了独特的视网膜生物标志物. 视网膜成像显示,在ASD中,圆形区域厚度增加,视网膜内动脉静脉口径减少,这表明早期诊断的潜力.
科学领域:
- 眼科和神经科学 眼科和神经科学
- 神经发育障碍 神经发育障碍
背景情况:
- 自闭症谱系障碍 (ASD) 诊断缺乏可靠的成像生物标志物.
- 眼睛与大脑相连,可以让人深入了解ASD.
- 以前的研究强调了早期发现自闭症的方法的必要性.
研究的目的:
- 通过使用OCT/OCTA调查潜在的视网膜成像生物标志物来发现ASD.
- 为了比较ASD儿童和典型发育 (TD) 儿童之间的黄斑区差异.
- 探索视网膜结构,血管功能和ASD之间的关系.
主要方法:
- 使用光学连贯断层扫描 (OCT) 和OCT血管扫描 (OCTA) 进行视网膜成像.
- 分析了被诊断为ASD和TD对照儿童的黄斑区域图像.
- 量化了视网膜层厚度和血管口径.
主要成果:
- 在ASD中显著增加圆形区域 (EZ) 厚度,含有形光受体,在ASD中.
- 在ASD个体的视网膜内部显著减少大口径动脉静脉.
- 这些EZ和动脉静脉变化在左眼中更为明显.
结论:
- 视网膜成像显示了ASD的独特特征,包括光受体和血管变化.
- 观察到EZ厚度和动脉静脉口径的变化可以作为潜在的ASD生物标志物.
- 这些发现的侧面化需要进一步调查,以获得诊断和病因学的见解.

01:19Autism Spectrum Disorder
79
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

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...
