| 7 | Changes on optical coherence tomography angiography and fluorescein angiography in eyes with neovascular age-related macular degeneration显示文摘AIM:lo evaluate the changes on optical coherence tomography angiography(OCTA) and fluorescein angiography(FA) and their correlation in neovascular agerelated macular degeneration(nAMD) before and after intravitreal aflibercept injections(IAIs).METHODS:In 43 treatment-na?ve patients with nAMD,choroidal neovascularization(CNV) in OCTA were morphologically and quantitatively analyzed before and after IAIs to determine whether they are correlated with leakage on FA or not.By combining CNV in OCTA and leakage in FA,lesions were characterized as three types:L+C+(with both CNV and leakage),L-C+(with CNV but without leakage),or L+C-lesion(with leakage outside CNV).RESULTS:Before IAI,while 27 eyes had L+C+lesion only,16 eyes had both L+C+and L-C+lesions simultaneously.Tiny capillaries and anastomosis in CNV were more developed in L+C+lesion,at 86.0% and58.1%,respectively,relative to 9.3% and 9.3% in L-C+lesions(P<0.001).After IAIs in 33 eyes,tiny capillaries and anastomosis were decreased in the lesions with cessation of leakage on FA(P<0.001 and P=0.001,respectively).In quantitative analysis,neovascularization length and numbers of junctions and endpoints were also significantly decreased.CONCLUSION:Leakage on FA is associated with CNV morphology in OCTA and remained so after IAls.Therefore,by carefully assessing the morphological and quantitative changes of CNV in OCTA before and after treatment,activity of nAMD is expected even though CNV on OCTA is not completely matched with fluorescein leakage. | So Min Ahn Mihyun Choi Cheolmin Yun Seong-Woo Kim Jaeryung Oh | 2022 | International Journal of Ophthalmology(English edition)2022，15，11： | 0 |
