Objective To observe the efficacy of intravitreal injection of aflibercept (IVA) in the treatment of exudative age-related macular degeneration (wAMD) combined with RPE detachment (PED).Methods A retrospective case study. From June 2018 to June 2019, 32 eyes (overall group) of 27 wAMD patients with PED were included in the study. All eyes were treated with IVA. The initial loading dose was 2.0 mg, which was injected once a month for 2 consecutive months and and then use a PRN regimen after evaluation. According to the maximum height of PED (PEDH) 2 months after treatment, the overall group was divided into the response group and the partial response group, with 20 (62.50%) and 12 (37.50%) eyes respectively. The response group: PEDH decreased by ≥25% compared with before treatment. The partial response: PEDH decreased by ＜25%. The macular fovea was scanned with the 3D-OCT 2000 instrument from Topcon (Japan). PEDH, PED area (PEDA), PED volume (PEDV), and macular foveal retinal thickness (CMT) were measured. There was no significant difference in BCVA, CMT, PEDH, PEDA, and PEDV of the eyes in the response group and the partial response group (t=－0.791, －0.488, －0.900, －1.130, －0.400; P=0.435, 0.630, 0.380, 0.270, 0.690). The changes of BCVA, PEDH, PEDA, PEDV, CMT in each group were observed before treatment and 1, 2, 4, and 6 months after treatment. The comparison of BCVA and PED-related indicators and CMT before and after treatment were performed by repeated measures analysis of variance.Results Compared with before treatment, the BCVA, CMT, PEDH, PEDA and PEDV of the eyes in the overall group, the response group, and the partial response group were obviously improved after treatment. Among them, there were statistically significant differences in all indicators of the overall group and the response group (F_BCVA=5.871, 3.798; P=0.001, 0.019. F_CMT=24.526, 14.109; P=0.000, 0.001. F_PEDH=12.569, 12.091; P=0.000, 0.000. F_PEDA=7.534, 6.286; P=0.000, 0.000. F_PEDV=5.139, 4.104; P=0.004, 0.014); there was no statistically significant difference in PED-related indicators in the partial response group (F_PEDH=3.210, P=0.054; F_PEDA=1.913, P=0.183; F_PEDV=3.500, P=0.051), the difference between BCVA and CMT was statistically significant (F_BCVA=3.033, P=0.027; F_CMT=11.140, P=0.001). Two months after treatment, the eye number of PEDH reduction rate ＜25%, 25%-＜50%, 50%-＜75%, and ≥75% were 12 (37.50%), 8 (25.00%), 9 (28.13%), and 3 (9.38%) in the overall group, respectively. And PED in one eye (3.13%) was completely eliminated. Six months after treatment, the proportion was 13 (40.23%), 5 (15.63%), 7 (21.88%) and 7 (21.88%), respectively, among which 4 eyes (12.50%) with PED were completely resolved.Conclusions Aflibercept treatment of wAMD combined with PED can restore its anatomical indicators and improve visual function of patients in a short time; the efficacy of PED in the PRN stage is related to the efficacy of the loading dose stage.
