| Popis: | AIM: To evaluate the changes on optical coherence tomography angiography (OCTA) and fluorescein angiography (FA) and their correlation in neovascular age-related macular degeneration (nAMD) before and after intravitreal aflibercept injections (IAIs). METHODS: In 43 treatment-naïve 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% and 58.1%, respectively, relative to 9.3% and 9.3% in L-C+ lesions (P |
