Initial macular SD-OCT (a) of a 43-year-old female diagnosed with idiopathic retinal vasculitis, revealing CME with a CFT of 493 μm (b) and a BCVA of 20/20. After four years of combined systemic immunosuppressive/biologic therapy and three sustained-release 700mm dexamethasone phosphate intravitreal implantations, CME (c) with a CFT of 607 μm (d) and a BCVA of 20/30 persist. The white arrowheads identify the integrity of EPIS and IZ retinal layers in both crossline SD-OCT images. SD-OCT spectral-domain optical coherence tomography, CME cystoid macular edema, CFT central foveal thickness, BCVA best corrected visual acuity, EPIS ellipsoid portion of inner segments, IZ interdigitating zone
