摘要
目前较多研究认为脉络膜厚度变化同多种因素相关,如脉络膜相关性疾病、年龄、屈光变化、体位等。以往受医疗技术和设备限制,人们无法详细观察脉络膜的形态及结构,光学相干断层成像技术(OCT)的出现实现了活体观察脉络膜横断面,具有安全性高、扫描速度快、信息丰富,并且使三维成像成为可能。运用OCT测量脉络膜厚度,为分析相关疾病的发病机制和指导疾病的预防及治疗具有重要意义。本文将对脉络膜功能、影响脉络膜厚度的相关因素及OCT扫描仪发展做一综述。
Many studies have suggested that changes in choroidal thickness are associated with a variety of factors.For example,choroidal related diseases,age,position,refractive changes,and so on.With the limitations of medical technology and equipment,there was no detailed observation of the morphology and structure of the choroid. The appearance of optical coherence tomography has realized the observation of choroidal cross section in vivo. It has high security,fast scanning speed,rich information and makes 3 d imaging possible. The use of this technique to measure the thickness of the choroid membrane is of great significance for the analysis of the pathogenesis of related diseases and the prevention and treatment of the disease.
