Abstract Background: The current study aimed to evaluate the efficacy of intravitreal aflibercept injections as the primary treatment for subfoveal/juxtafoveal myopic choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA) to detect the changes in shape, size, and flow area pertaining to CNV, with a minimum duration of follow-up of one year. Methods: In the present study, 21 treatment-naive eyes of 21 patients with subfoveal/juxtafoveal myopic CNV received primary intravitreal aflibercept injections and were under follow-up for a minimum duration of 12 months. Among the 21 patients, 12 underwent OCTA to evaluate the changes in central foveal thickness, selected CNV area, and flow area. Results: The mean best-corrected visual acuity (BCVA) pertaining to all the patients significantly improved from the baseline value of 0.7 to 0.3 logMAR after treatment for 12 months (P = 0.001). However, the improvements in the median BCVA after treatment for three and twelve months were not statistically significant in the younger group (< 50 years), compared to the older group (≥ 50 years). A single aflibercept injection resolved the CNV in 47.6% (10/21) of the patients. The younger group displayed greater improvement in the median central foveal thickness, compared to the older group. OCTA revealed interlacing or disorganized patterns at the level of the outer retinal layer in 12 among the 21 subjects with myopic CNV. After three months of treatment, both the groups displayed a decrease in the size of the selected CNV area and flow area. The interlacing group displayed a trend towards better anatomical improvements. Conclusion: Intravitreal aflibercept injection provides long-term improvement in visual acuity in patients with myopic CNV. A single aflibercept injection was observed to resolve myopic CNV in approximately half of the patients. The interlacing group displayed greater resolution of the selected CNV area and flow area after aflibercept injection. Trial registration: Before data collection, written informed consent was obtained from each participant, whose identity information was protected by encryption and conversion to a non-identifiable format and removing data links. This study was approved by the Institutional Review Board of Kaohsiung Veterans General Hospital (KSVGH21-CT1-17).

<strong>Introduction:</strong> Choroidal neovascularization secondary to pathological myopia is one of the leading causes of irreversible central vision loss in younger patients. The purposes of our study is to evaluate the long-term results of antiangiogenic treatment, with ranibizumab and/or bevacizumab, in myopic choroidal neovascularization and define the predictive factors for visual and anatomic outcomes.<br /><strong>Material and Methods:</strong> In this study were included 84 eyes from 81 patients with myopic choroidal neovascularization. Eighty-four (100%) eyes accomplish 12 months of follow-up, 67 (79.8%) 24 months, 54 (64.3%) 36 months, 29 (34.5%) 48 months, and 15 (16.7%) 60 months. We retrieved data related to best corrected visual acuity measured with ETDRS chart, foveal center thickness on optical coherence tomography and fluorescein angiographic findings, before and after treatment.<br />Results: The best corrected visual acuity and foveal center thickness improvements were statistically significant for all follow-up times (p &lt; 0.05). Mean baseline best corrected visual acuity was 43.7 ± 20.1 letters and mean baseline foveal center thickness was 304.8 ± 127.9μm. Mean best corrected visual acuity was 55.6 ± 18.5, 52.1 ± 22.3, 52.1 ± 22.6, 50.3 ± 23.8 and 47.8 ± 24.5 for 12, 24, 36, 48 and 60 months of treatment, respectively. Mean foveal center thickness was 209.7 ± 86.2, 190.6 ± 76.1, 174.7 ± 60.6, 189.8 ± 96.7 and 159.4 ± 73.3 for the same follow-up times. Baseline best corrected visual acuity was the only predictive factor for better visual outcome (p &lt; 0.001).<br /><strong>Discussion/Conclusion:</strong> Intravitreal anti-VEGF injections in patients with myopic choroidal neovascularization yielded a significant and sustained functional and anatomic improvement. Randomized long-term clinical trials are needed to determine the sustained efficacy of these drugs.
