All patients received 3 initial loading intravitreal injections every 4 weeks, followed by a TAE protocol. The primary outcome was decimal best-corrected visual acuity (BCVA) at year 3.Results: Overall, mean decimal BCVA increased significantly from 0.44 (SD; 0.35) at baseline to 0.59 (SD; 0.31) at the final visit (p˂0.001). At year 3, mean decimal BCVA in the PDT-treated group compared to the naive group was statistically different, 0.48 (SD; 0.29) vs 0.71 (SD; 0.31), respectively (p=0.04). Overall, complete resolution of fluid was noted in 73% at 3 years. Complete resolution of fluid in the PDT-treated group and the naive group was 56% and 89% (p=0.01), respectively. The total mean number of aflibercept injections was 18.0 (SD; 5.6). Mean number of injections was 20.1 (SD; 5.3) in the PDT-treated group and 15.9 (SD; 5.8) in the naive group (p=0.03).Conclusion: Intravitreal aflibercept using a TAE regimen improved visual and anatomical outcomes of patients with type 1 CNV secondary to chronic CSC in long-term follow-up. Naive patients had a better visual outcome and a higher incidence of complete fluid resolution than PDT-treated patients.Keywords: chronic central serous chorioretinopathy, choroidal neovascularization, anti-vascular endothelial growth factor, aflibercept, treat-and-extend regimen |
