摘要

目的观察人眼后皮质前玻璃体囊袋(PPVP)的OCT图像特征。方法回顾性临床研究。2012年5月至2017年2月，成都市第三人民医院眼科通过OCT诊断的PPVP患者107例(173只眼)纳入研究。频率域OCT (SD-OCT)检查103只眼，频率扫描光源OCT (SS-OCT)检查70只眼。SD-OCT:德国海德堡光谱OCT仪器。SS-OCT采用日本Topcon DRI OCT仪玻璃体增强扫描模式。观察不同类型PPVP OCT成像及图像特征的差异。结果SD-OCT和SS-OCT显示PPVP结构清晰，表现为黄斑弱反射，呈船形腔状，前界为玻璃体胶原，后界为玻璃体皮质。PPVP鼻侧有弱反射的Martegiani区，两者之间有连接通道。两次检查显示相似的模式，但SS-OCT具有更清晰的PPVP图像。结论人眼PPVP的OCT图像表现为黄斑前向弱反射船型空洞，前缘为玻璃体胶原，后缘为玻璃体皮质。马氏区位于鼻侧。关键词:层析成像;光学相干;后皮质前玻璃体袋

The image characteristics of optical coherence tomography of the posterior cortical anterior vitreous capsular bag in human eyes

Objective To observe the OCT image characteristics of the posterior cortical anterior vitreous capsular bag (PPVP) in human eyes. Methods A retrospective clinical study. From May 2012 to February 2017, 107 PPVP patients (173 eyes) diagnosed by OCT in Ophthalmology Department of The Third People's Hospital of Chengdu were included in the study. One hundred and three eyes underwent examination of frequency-domain OCT (SD-OCT) and 70 eyes underwent examination of frequency-scanning light source OCT (SS-OCT), respectively. SD-OCT the German Heidelberg Spectralis OCT instrument. SS-OCT was performed by the vitreous enhancement scan mode of Japan's Topcon DRI OCT instrument. The differences of different types of PPVP OCT imaging and image characteristics were observed. Results SD-OCT and SS-OCT showed that the PPVP structure was clear and manifested as macular weakly reflective in the shape of a boat-shaped cavity, the front boundary was vitreous collagen, and the rear boundary was vitreous cortex. There was a weakly reflective Martegiani area on the nasal side of PPVP, and there was a connection channels between them. The two examinations showed a similar pattern, but SS-OCT with the clearer imaging of PPVP. Conclusions The OCT image of PPVP in the human eye is characterized by an anterior weakly reflecting boat-shaped cavity in the macula, with anterior border of vitreous collagen and posterior border of vitreous cortex. Martegiani area is located on the nasal side. Key words: Tomography, optical coherence; Posterior precortical vitreous pockets

期刊介绍： Chinese Journal of Ocular Fundus Diseases is the only scientific journal in my country that focuses on reporting fundus diseases. Its purpose is to combine clinical and basic research, and to give equal importance to improvement and popularization. It comprehensively reflects the leading clinical and basic research results of fundus disease disciplines in my country; cultivates professional talents in fundus disease, promotes the development of fundus disease disciplines in my country; and promotes academic exchanges on fundus disease at home and abroad. The coverage includes clinical and basic research results of posterior segment diseases such as retina, uveal tract, vitreous body, visual pathway, and internal eye diseases related to systemic diseases. The readers are medical workers and researchers related to clinical and basic research of fundus diseases. According to the journal retrieval report of the Chinese Institute of Scientific and Technological Information, the comprehensive ranking impact factor and total citation frequency of the Chinese Journal of Ocular Fundus Diseases have been among the best in the disciplines of ophthalmology, otolaryngology, and ophthalmology in my country for many years. The papers published have been included in many important databases at home and abroad, such as Scopus, Peking University Core, and China Science Citation Database (CSCD).
