目的:采用光学相干断层扫描血管成像(OCTA)技术观察视网膜分支静脉阻塞(BRVO)患者黄斑区血流及结构特征,并分析视力的危险因素。方法:收集2018-01/2019-06在抚顺市眼病医院经眼底及眼底荧光造影检查确诊的BRVO患者92例92眼为BRVO组,另... 目的:采用光学相干断层扫描血管成像(OCTA)技术观察视网膜分支静脉阻塞(BRVO)患者黄斑区血流及结构特征,并分析视力的危险因素。方法:收集2018-01/2019-06在抚顺市眼病医院经眼底及眼底荧光造影检查确诊的BRVO患者92例92眼为BRVO组,另选取同期基线资料与BRVO组患者相匹配的健康志愿者38例38眼作为对照组。记录两组受检者的基线资料,并采用OCTA技术观察3mm×3mm范围内黄斑区深层和浅层血流密度、深层和浅层中心凹血流密度、黄斑中心凹厚度、神经上皮层厚度、神经上皮层下积液高度。分析BRVO患者上述参数的相关性,并采用多因素Logistic回归法分析影响视力的危险因素。结果:与对照组相比,BRVO患者视力、黄斑中心凹厚度、深层血流密度、浅层血流密度、深层中心凹血流密度、浅层中心凹血流密度均有差异(P<0.01)。多因素Logistic回归分析显示,年龄(P=0.033,OR=1.152,95%CI 1.011~1.312)、浅层中心凹血流密度(P=0.010,OR=1.260,95%CI 1.056~1.504)、黄斑中心凹厚度(P<0.01,OR=1.033,95%CI 1.021~1.045)均是视力的危险因素。BRVO患者深层及浅层血流密度与黄斑中心凹厚度、神经上皮层厚度均呈负相关(P<0.01),黄斑中心凹厚度与神经上皮层厚度、神经上皮层下积液高度均呈正相关(P<0.01)。结论:利用OCTA可以观察BRVO患者视网膜血流状态及视网膜切面结构的变化,将两者结合起来可以更全面地观察BRVO患者黄斑区视网膜的病变特点。年龄、黄斑中心凹厚度、浅层中心凹血流密度为影响视力的危险因素。 展开更多

AIM:To estimate the prevalence of diabetic macular edema(DME) and clinically significant macular edema(CSME),and to assess their risk factors in a population with type 2 diabetic mellitus(T2DM) located in northeast China.METHODS:Patients were included from the Fushun Diabetic Retinopathy Cohort Study(FS-DIRECT),a community-based study conducted in northeast China.The presence of DME and CSME was determined by the Early Treatment Diabetic Retinopathy Study(ETDRS) retinopathy scale of fundus photographs.The age-standardized prevalence of DME and CSME was estimated.The association between DME/CSME and risk factors was analyzed in a multivariate Logistical analysis.RESULTS:A total of 292(15.4%) and 166(8.8%) patients were diagnosed as DME and CSME,yielding the age and sex standardized prevalence of 13.5%(95%CI:11.9%-15.0%),and 7.1%(95%CI:5.9%-8.3%),respectively.Female patients had a higher prevalence of DME compared to their male counterparts(15.7% vs 10.4%,P=0.03).Multivariable Logistic regression analysis showed that younger age,insulin use,proteinuria,longer duration of diabetes,and higher glycosylated hemoglobin A1c,were associated with the prevalence of DME and CSME.Patients with higher fasting plasma glucose,systolic blood pressure,and blood urea nitrogen were also found to be associated with DME.CONCLUSION:Early fundus screening in diabetic patients is invaluable and given the relatively high prevalence of DME and CSME in this study cohort,those with a high risk of sight threatening maculopathy would invariably benefit from earlier detection. 展开更多
