摘要

目的观察单目视网膜静脉阻塞（RVO）患者随访眼黄斑血管密度和中央凹无血管区面积。方法回顾性病例对照研究。2018年5月至11月，长沙爱尔眼科医院临床诊断的78例单眼RVO患者的78只随访眼睛被纳入研究。其中男性44例，女性34例。平均年龄53.17±10.12岁。视网膜中央静脉闭塞42例（CRVO组），视网膜分支静脉闭塞36例（BRVO组）。选择33名性别和年龄匹配的健康志愿者42只眼睛作为对照组。其中男性17例（22眼），女性16例（20眼），平均年龄53.48±10.84岁。CRVO组、BRVO组和对照组均行OCT血管造影术。黄斑区的扫描范围为6mm×6mm。测量视网膜浅部和深部毛细血管丛的黄斑血管密度和FAZ面积。结果CRVO组（t=-4.26，-4.93）和BRVO组（t=-4.79，-4.74）在整个扫描过程中测量的平均总血管密度均低于对照组（P 0.05）。深部毛细血管丛的血管密度降低程度高于浅部血管丛。与正常健康眼相比，单眼CRVO患者随访眼的FAZ面积减少，而单眼BRVO患者随访眼中的FAZ区域没有显著变化。关键词：视网膜静脉阻塞；局部血流；层析相干性

The macular vascular density and the area of foveal avascular zone in the follow eyes of monocular retinal vein occlusion patients

Objective To observe the macular vascular density and the area of foveal avascular zone(FAZ) in the follow eyes of monocular retinal vein occlusion (RVO) patients. Methods Retrospective case-control study. From May to November 2018, 78 follow eyes of 78 monocular RVO patients who were clinically diagnosed in Changsha Aier Eye Hospital were included in the study. Among them, 44 were male and 34 were female. The average age was 53.17±10.12 years. There were 42 patients with central retinal vein occlusion(CRVO group) and 36 patients with branch retinal vein occlusion (BRVO group). Forty-two eyes of 33 gender and age matched healthy volunteers were selected as the control group. Among them, 17 were male (22 eyes) and 16 were female (20 eyes), with the mean age of 53.48±10.84 years. OCT angiography was performed on all eyes in CRVO group, BRVO group and control group. The scanning region in the macular area was 6 mm× 6 mm. Macular vascular density and FAZ area in the superficial and deep retinal capillary plexi were measured. Results The mean overall vascular density measured in the entire scan was lower in the CRVO group(t=-4.26, -4.93) and BRVO group (t=-4.79, -4.74) compared with the control group in both the superficial and deep capillary plexus (P 0.05). Conclusions The macular vascular density in the follow eyes of monocular RVO patients is lower than that of normal healthy eyes. The reduce degree of vascular density in the deep capillary plexus is higher than that in the superficial plexus. Compared with normal healthy eyes, the FAZ area in the follow eyes of monocular CRVO patients decreased, while it did not change significantly in the follow eyes of monocular BRVO patients.

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).
