A patient with diabetic macular edema who underwent intravitreal triamcinolone injection. (A) Fundus photograph. (B) Optical coherence tomography (OCT) image. There are several intraretinal cysts. (C) OCT image with optical coherence tomography angiography (OCTA) signal. The largest intraretinal cyst (arrow) has OCTA signal, while other intraretinal cysts do not have OCTA signal (arrowhead). (D) OCT image before treatment; the largest intraretinal cyst is 0.04 mm2 in size. (E) OCT image one month after intravitreal triamcinolone injection; the largest intraretinal cyst size is 0.02 mm2, a reduction of 48.14%. (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) without SSPiM before treatment. (H) OCTA image including INL with decreased SSPiM after treatment (arrow). (I) OCTA image including ONL without SSPiM after treatment.
