Figure 2: Spectral-domain optical coherence tomography (SD-OCT) scans passing through the lesions are shown. In the scan just below the fovea (a), there is presence of an intraretinal cystoid space (CS) at the involving the center of the macula. The CS consists of fluid of heterogenous reflectivity. A scan below this area shows accumulation of intraretinal fluid with membranous/amorphous hyper-reflective material (b). Magnified image of panel A is depicted in panel c, and magnified image of b is shown in d. The external limiting membrane (ELM) is seen coursing anterior to the CS. The hypo-reflective myoid zone (MZ) has split, forming a bacillary layer detachment (BLD). The ellipsoid zone (EZ) shows irregularity, and the floor of the cystoid space contains the remnant photoreceptor segments (d; asterisk). The outer segments (OS), interdigitation zone (IZ) remain adherent to the retinal pigment epithelium-Bruch's membrane (RPE-BrM). The choroidal granuloma appears as a homogenous lobulated area of hyporeflectivity in the stroma (CG). The OCT B-scan passing further inferiorly (e) shows the inferior limit of the CS (white arrowhead)
