青光眼是一组以视网膜神经节细胞和轴突逐渐丢失为特征的视神经损害性疾病。已有研究证实青光眼的视盘周围神经纤维层结构改变明显早于其功能改变,检测视盘周围神经纤维缺失有助于青光眼的早期诊断及随访治疗。目前,计算机辅助系统客观检查仪器具备良好的可重复性、敏感性和特异性,本文将激光偏振扫描仪、海德堡视网膜断层扫描仪、光学相干断层扫描仪的运用原理、检测能力以及现有技术局限性综述如下。
Glaucoma is a group of optic nerve degenerative diseases characterized by progressive loss of retinal ganglion cells and axons. Studies have confirmed that changes in the structure of the optic nerve fiber layer around the optic disc of the glaucoma were significantly earlier than their functional changes. Detecting the loss of nerve fibers around the optic disc is helpful for the early diagnosis and follow-up of glaucoma. At present, computer-aided system objective examination instrument with good repeatability, sensitivity and specificity, this paper laser polarization scanner, Heidelberg retina tomography, optical coherence tomography scanner principle, detection capabilities and limitations of the existing technology Sexual summary is as follows.
