摘　　要：目的相干光层析血管成像术(OCTA)观察视网膜脱离患者行玻璃体切除联合硅油填充术后视网膜黄斑区和视盘区血流变化情况。方法回顾性病例研究。收集2021年5月至2022年2月于蚌埠医学院第一附属医院行玻璃体切除术联合硅油填充的患者30例(30只眼)。通过OCTA观察患者术后1周、1个月、3个月、6个月黄斑区浅层视网膜毛细血管丛血流密度(SCP)、深层视网膜毛细血管丛血流密度(DCP)、中心凹无血管区面积(FAZ),视盘血流密度(DBD)的变化情况,同时观察其最佳矫正视力(BCVA)。结果硅油填充眼内后,患者1、3个月BCVA优于术后1周(P<0.05),术后6月BCVA差于术后1、3个月(均P<0.05),与术后1周比较差异无统计学意义(P>0.05);患者1、3个月黄斑区SCP、DCP、FAZ与术后1周相比差异无统计学意义(均P>0.05),术后1个月与术后3个月相比差异无统计学意义(均P>0.05),术后6个月与术后1、3个月比较SCP明显降低(均P<0.05);患者术后1、3个月视盘血流密度与术后1周相比差异均无统计学意义(P>0.05),术后1个月与术后3个月比较差异无统计学意义(P>0.05),术后6个月与术后1、3个月比较密度降低(均P<0.05)。结论使用OCTA观察视网膜脱离行玻璃体切除联合硅油填充后不同时期的黄斑区和视盘血流密度,对于评估视力预后,监测黄斑区和视盘血流密度及结构功能的变化有重要意义。Objective Optical coherence tomography angiography(OCTA)was used to observe the changes of blood flow in macula and optic disc after vitrectomy combined with silicone oil filling in patients with retinal detachment.Methods Retrospective case study.Thirty patients(30 eyes)who underwent vitrectomy combined with silicone oil filling in the First Affiliated Hospital of Bengbu Medical College from May 2021 to February 2022 were collected.By viewing the OCTA patients postoperative 1 week,1 month,3 months,6 months in the macular area of shallow retinal capillary plexus blood flow density(superficial capillary plexus flowc density,SCP),deep retinal capillary plexus blood flow density(deep capillary plexus,DCP),the foveal avascular zone area(foveal avascular zone FAZ),(disc bloodflow density,DBD)changes of the density of blood flow,at the same time observe the best corrected visual acuity,(Best corrected visual acuity,BCVA).Results After filling the eyes with silicone oil,BCVA in 1 and 3 months was better than that in 1 week after surgery(P<0.05),BCVA in 6 months after surgery was worse than that in 1 and 3 months after surgery(all P<0.05),and there was no statistical significance between BCVA and 1 week after surgery(P>0.05).There was no significant difference in SCP,DCP,FAZ of macular area in 1 and 3 months compared with 1 week after surgery(all P>0.05),no significant difference between 1 and 3 months after surgery(all P>0.05),and SCP significantly decreased in 6 months after surgery compared with 1 and 3 months after surgery(all P<0.05).There was no significant difference in blood flow density in optic disc 1 and 3 months after surgery compared with 1 week after surgery(P>0.05),no significant difference between 1 and 3 months after surgery(all P>0.05),and density decreased 6 months after surgery compared with 1 and 3 months after surgery(all P<0.05).Conclusions The use of OCTA to observe the blood density in macular area and optic disc at different periods after vitrectomy combined with silicone oil filling is of great
