case_images: A second OCT scan showed a fluid bulge below the fovea in the left eye and a disordered, uneven signal in the right macular region with significant fluid accumulation underneath ( Figure 2 ).
case_images: Binocular macular optical coherence tomography scanning through the (A) right and (B) left eyes showing a subretinal lesion of the right eye with elevated pigment epithelium and neuroepithelium in the macular region and mild cystic macular edema in the left eye.
