a, b SD-OCT images on day −1. Day −1 indicates the day before the initiation of systemic steroid therapy. SD-OCT images of both eyes showing serous retinal detachment with a subretinal septum and an intraretinal compartmentalized cystic space. The compartmentalized intraretinal space was observed to contain two hyperreflective membranous layers (white arrow). In the left eye, PED was observed (red arrow). c, d On day 1, SD-OCT revealed that the subretinal fluid began to decrease. Disruption of the hyperreflective membranous layers in the intraretinal spaces (orange arrow) was observed. Day 1 indicates the first day after initiation of systemic steroid therapy. e, f On day 3, the amount of subretinal fluid almost disappeared, but the IS/OS line remained disorganized in the affected area. Day 3 indicates the third day after initiation of systemic steroid therapy.
