摘要:
目的:通过光学相干断层扫描血管成像(OCTA)检查视网膜静脉阻塞患者黄斑区表层血管骨架、血流密度和无血管区,观察视网膜静脉阻塞患者黄斑区视网膜表层血流变化。方法:研究组纳入38例,视网膜静脉阻塞患者38眼,取年龄相匹配的60例,健康者60眼作为对照组。所有观察对象均进行裂隙灯、眼压、B超和眼轴测量,应用OCTA对黄斑区视网膜行3 mm×3 mm、6 mm×6 mm范围模式扫描,测量黄斑区视网膜表层血管骨架长度、血流密度和无血管区。结果:3 mm×3 mm范围和6 mm×6 mm范围扫描模式下,视网膜静脉阻塞患者黄斑区视网膜表层血管骨架长度下降、血流密度降低、黄斑无血管区扩大、充实度降低,与健康对照组相比,差异具有统计学意义(P<0.05)。结论:视网膜静脉阻塞患者黄斑区表层视网膜血流下降,OCTA可以量化黄斑区视网膜表层血流变化的情况,可作为监测病情进展、评估预后的有效手段。
