OCT在检测糖尿病患者脉络膜厚度研究中的进展

Progress in the study of choroidal thickness on diabetic retinopathy by OCT

摘要:

脉络膜为外层视网膜提供氧和营养，维持光感受器细胞的代谢活性，其血管系统的正常结构与功能对于视网膜显得尤为重要。所以观察脉络膜形态对于跟踪糖尿病患者的病理变化较有意义。随着高分辨率光学相干断层扫描(optical coherence tomography，OCT)技术的应用，频域光学相干断层扫描(spectral-domain optical coherence tomography，SD-OCT)深度增强成像技术(enhanced depth imaging-technique，EDI)可定量测量脉络膜厚度，为诊断及治疗糖尿病视网膜病变提供了新的思路。在此，我们对OCT在检测糖尿病患者脉络膜厚度中的研究进展进行综述。

Abstract:

The choroidal vasculature provides oxygen and nutrients to the outer retina, and is responsible for maintaining the highly metabolically active photoreceptor cells. The normal structure and function of its vascular system is very important for the retina. So it is more meaningful to observe the choroid morphology for tracking pathological changes in diabetic retinopathy. With the application of the high resolution optical coherence tomography(OCT)technology, spectral-domain optical coherence tomography(SD-OCT)enhanced depth imaging technology can be used to measure the choroidal thickness quantitatively, which provides a new idea for the diagnosis and treatment of diabetic retinopathy. Therefore, the research and progress of choroidal thickness on diabetic retinopathy by OCT are summarized as follows.
