刚刚讲到OCT主要用于看视网膜形态学改变,这里简单回顾下视网膜:视网膜是接受光信号并将其转化为电信号的部位,具有明显的分层结构(图1),其中图中最下面的视杆细胞和视椎细胞对光信号最敏感,它们也是最先接受光信号并将其转化为电信号的部位,这些信...

Ganglion cell layerOptical coherence tomography (OCT) has become essential to evaluate axonal/neuronal integrity, to assess disease progression in the afferent visual pathway and to predict visual recovery after surgery in compressive optic neuropathies. Besides that OCT testing is considered a powerful ...
G/O)和神经节细胞复合体与黄斑区总视网膜厚度比(ganglion cell complex/total retinal layer,G/T)的概念,证明G/O和G/T随青光眼严重程度的加重而变小,在近视眼人群中却与眼轴延长和屈光度均无关[38, 62],即说明这两个值不随近视的加重而改变。

因此我们假设RGCs更易受到缺血性脑卒中的影响,且神经节细胞层(ganglion cell layer,GCL)与视网膜全层,即内界膜(inner limiting membrane)至视网膜色素上皮层(retinal pigment epithelium)的厚度比更能体现出神经节细胞层的厚度变化。本研究使用光学相干断层扫描(optical coherence tomography,OCT)检测新发缺血性脑卒中...
青光眼是全球范围内导致失明的主要原因之一,它会造成渐进性且不可逆的视力丧失,严重影响患者的生活质量。青光眼的主要特征是视野逐渐受损,这是由于神经节细胞(Ganglion Cell,GC)死亡、轴突丢失等结构变化,导致视网膜神经纤维层(Retinal Nerve Fiber Layer,RNFL)出现缺损以及神经视网膜边缘变薄。

The neuroretina is part of the brain, comprised of first-order neurons that relay visual information to the lateral geniculate nucleus (LGN) in the thalamus. While these ganglion cell layer (GCL) neurons are susceptible to primary pathologies affecting the retinal nerve fiber layer (RNFL) axons,...
