摘　　要：目的分析光相干断层扫描血管成像(OCTA)下硅油填充术后视盘血流密度的变化。方法选取我院2018年1月至2018年10月行玻璃体切除联合硅油填充术的孔源性视网膜脱离患者20例作为观察组,另选取同期健康体检者20例作为对照组。使用OCTA检测观察组填充前,填充1周、 1个月及3个月后的视盘周围毛细血管血流密度、视盘血流密度、盘内毛细血流密度,并与对照组进行对比。结果观察组填充前后的视盘周围毛细血管血流密度、视盘血流密度、盘内毛细血管血流密度均显著低于对照组(P <0.05)。观察组填充前后的上述指标比较差异均无统计学意义(P>0.05)。结论硅油眼内填充3个月并未明显改变视盘血流密度。Objective To analyze the changes of optic disc blood flow density after silicone oil filling under optical coherence tomography angiography(OCTA).Methods 20 cases of patients with rhegmatogenous retinal detachment undergoing vitrectomy combined with silicone oil filling in our hospital from January 2018 to October 2018 were selected as observation group,and another 20 people with healthy physical examination at the same period were selected as control group.The peripapillary capillary blood flow density,optic disc blood flow density and inner optic disc capillary blood flow density before filling,1 week after filling,1 month after filling and 3 months after filling were detected by OCTA,which were compared with the control group.Results The peripapillary capillary blood flow density,optic disc blood flow density and inner optic disc capillary blood flow density before and after filling of observation group were significantly lower than those of control group(P<0.05).No statistical difference was found in the above indicators before and after filling in observation group(P>0.05).Conclusions The optic disc blood flow density does not change significantly 3 months after silicone oil filling.
