The value of color Doppler ultrasound in the detection of macular diseases in age-related cataract patients / 中华眼底病杂志

ABSTRACT

Objective To observe the application value with color Doppler flow imaging (CDFI) in the detection ofmacular diseases in senile cataract.Methods A cross-sectional descriptive study.From December 1 to December 30,2017,720 senile cataract patients (1380 eyes) diagnosed in Beijing Tongren Eye Center were included in this study.There were 330 males (629 eyes) and 390 females (751 eyes),with the mean age of 70.35 ± 19.05 years.There were 716 right eyes and 664 left eyes,with the visual acuity 0.05-0.8.The fundus of all the patients can be observed.All patients were examined by OCT using Cirrus HD-Model 5000 produced by German Carl Zeiss company and CDFI using MyLab90 color Doppler ultrasound system produced by ESAOTE S.P.A.Comparing the detection rate of macular lesions between the two methods by using X2 test.Using statistical methods to evaluate diagnostic tests,a crosstabulation was made to compare the consistency of frequency-domain OCT and CDFI in the diagnosis of macular lesions.Logistic regression analysis of correlation between detection of CDFI macular lesions and central foveal thickness (CFT),average thickness (AT),with or without macular anterior membrane,retinal folds,retinal cystoid edema,hard exudation,macular hole or lamellar macular hole,superficial detachment of neuroepithelium,detachment of pigment epithelium,vitreous macular traction.Results Two hundreds and thirty-nine eyes (17.3％) showed macular disease by OCT,and 161 eyes (11.7％) showed the abnormal echo in the macular region by CDFI.The detection rate of the macular disease between two methods were statistically significant (χ2=851.661,P＜ 0.001),however,the consistency was well (r=0.766,P=0.000).Logistic analysis showed that the detection rate of macular lesions was related to retinal folds,cysts in retina and CFT (r=1.396,1.041,0.12;P＜0.01).Conclusion CDFI can effectively detect macular lesions that affect the visual prognosis of senile cataract patients.
