a, b OCT images of both eyes of the patient. OCT at the initial visit showed a fluid accumulating between the neurosensory retina and RPE. In addition, membranous structure and cystoid spaces were found in the left eye; c, d One week after glucocorticoid treatment, the fluid was resorbed, the inflammatory interval faded, the subretinal fluid in the macular area of the left eye was resorbed, some hyperreflective signals were visible in the outer retina, and similar retinal changes were also seen in the right eye; e, f OCT showed absorption of subretinal fluid and inflammatory deposits in the macular area of the left eye, disruption of the outer retinal strips, thinning of the outer nuclear layer, the outer plexiform layer appeared to be directly connected to the outer membrane and RPE layer, absence of the myoid band, ellipsoid band and outer photoreceptor segments, similar outer retinal lesions, also seen in the temporal side of the right eye, at 18-month follow-up visit; g, h OCT showed further reorganization and normalization of the outer retinal structures, whose outer nuclear layer had regained its normal hyporeflectivity, with partial reappearance of the ellipsoid band outer segmental membrane disc light band at the fovea, and ongoing reorganization at the connection with the RPE; the ellipsoid band was still missing in the temporal side of the right eye, but the outer retinal layer at the lesion was being reorganized, at 28-month follow-up visit
