概括
囊症会导致光盘中的晶体积聚,导致患者出现更厚的外皮皮质视网膜神经纤维层 (pRNFL) 和更薄的斑点质细胞层 (mGCL). 这项研究强调了囊病患者早期的眼部变化.
科学领域:
- 眼科医生 眼科 眼科
- 遗传学 是一个遗传学.
- 代谢疾病 代谢疾病
背景情况:
- 囊病是一种 lysosomal 储存疾病,其特征是囊晶体的积累.
- 囊病的眼部表现已有充分证据,特别是角膜晶体沉积.
- 在囊病中,神经膜结构尚未得到广泛的研究.
研究的目的:
- 为了研究患有囊病的患者的神经管结构.
- 用光学相干断层扫描 (OCT) 分析光盘和黄斑变化.
- 为了比较囊病患者的眼睛发现与健康对照.
主要方法:
- 对40名囊病患者和30名健康对照组的回顾性横截面分析.
- 光学连贯性断层扫描 (OCT) 用于测量周周状视网膜神经纤维层 (pRNFL),光盘体积,前层深度和斑点质细胞层 (mGCL) 体积.
- 测量结果比较了囊症组和年龄和球体等效 (SE) 匹配的对照组.
主要成果:
- 所有的囊病患者都表现出明显的光盘晶体沉积,呈珍珠串状的图案.
- 囊炎组表现出明显更厚的pRNFL (839.7 ± 151.0 微米对比775.7 ± 79.6 微米,p=0.004).
- 在囊病患者中观察到显著较小的mGCL体积 (0.25 ± 0.03 mm3对比0.35 ± 0.03 mm3,p=0.036).
结论:
- 囊症导致早期和明显的光盘晶体积累,表明质局部化.
- 较厚的pRNFL和在OCT扫描中增加的阳性前层层深度有助于囊炎中光盘拥挤.
- 显著的视网膜神经退行,由GCL稀释证明,发生在囊病患者中,可能是由于代谢因素.

Renal Corpuscle
7.0K
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...
