Efficacy and Safety of Intravitreal Aflibercept Injection for Subacute Central Serous Chorioretinopathy

"2mg intravitreal Aflibercept(Eylea) injection at baseline, at 1 month, and at 2 month.~At 3 month, 4 month, 5 month, and 6 month, PRN treatment of aflibercept injection or half-fluence photodynamic therapy may be done, if one of following conditions is fulfilled.~The PRN treatment method was decided by investigator's discretion.~Of patient who had persistent intra- or subretina fluid on SD-OCT~1. Central subfield thickness is not decreased to more than 50 micrometer compared with baseline central subfield thickness~2. Best-corrected ETDRS letter score dose not increased more than 5 letters than baseline (because of the persistent CSC).~3. Central subfield thickness is thicker than the previous exam~4. BCVA letter score is worse than the previous exam (because of the persistent CSC)"
