case_images: Fluorescein angiography revealed non-specific signs, with only a window defect caused by retinal pigment epithelium (RPE) atrophy (Fig. 1).
case_images: Optical coherence tomography of the macular area revealed no definite abnormal findings.

case_images: Optical coherence tomography also revealed non-specific finding in the fovea (Fig. 2).
case_images: The multifocal electroretinogram demonstrated foveal suppression in both eyes (A,B). A central scotoma was noted on central 10-2 threshold visual field testing (C,D). MD=mean deviation; PSD=pattern standard deviation.

case_images: Multifocal ERG showed decreased amplitude in the central ring one in both eyes (Fig. 3A and 3B). The Humphrey perimeter (Humphrey Instruments Inc., San Leandro, CA, USA) static visual field with central 10-2 threshold test revealed a central scotoma (Fig. 3C and 3D).
case_images: Visual evoked potential (VEP) revealed P100 delay in both eyes.
