A patient with diabetic macular edema who underwent intravitreal triamcinolone injection. (A) Fundus photograph. (B) Optical coherence tomography (OCT) image. There is an intraretinal cyst with hyperreflective foci. (C) OCT image with optical coherence tomography angiography (OCTA) signal of the intraretinal cyst. (D) OCT image before treatment of an intraretinal cyst 0.07 mm2 in size. (E) OCT image one month after intravitreal triamcinolone injection; the largest intraretinal cyst remains and is 0.09 mm2 in size. Small intraretinal cysts without OCTA signal have disappeared. (F) OCTA image including inner nuclear layer (INL) with suspended scattering particles in motion (SSPiM) before treatment (arrow). (G) OCTA image including outer nuclear layer (ONL) before treatment without SSPiM. (H) OCTA image including INL after treatment with decreased SSPiM (arrow). (I) OCTA image including ONL after treatment without SSPiM.
